Brush, Paint, for Chalkboard, 50-60mm (Product Code: SLE/CS/020) is a flat paint brush sized for recoating chalkboards, giving an even application and a smooth finish so the repainted surface writes cleanly. Its head is 50-60mm wide, a practical width for board panels, slates and wall-mounted writing areas. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of the classroom and lab equipment accessories India's schools order for board upkeep.

Specifications

Typical Use

Load only the front third of the bristles, wipe the excess on the rim of the tin, and draw the brush across the board in long, parallel strokes from one edge to the other. Finish each section with light strokes in the same direction so brush marks level out, and work the paint carefully around the edges and corners of the panel. The 50-60mm width covers a large board quickly while still being narrow enough for slates and frame edges.

Clean the brush immediately after use with the cleaning method printed on the paint label, reshape the bristles and let it dry hanging or lying flat so they stay straight for the next job. Schools carrying out a classroom or school lab renovation in India usually keep a few brushes with the paint stock so boards can be refreshed during each long holiday.

Blackboard, Double-sided, 1160 x 760 mm (Product Code: SLE/CS/021) is a frameless chalkboard panel with a writing surface on both faces, made from highly pressed insulite-type fibre board and finished in black blackboard paint on both sides and all four edges. Two eyelets along the long side let it hang from a wall hook, a tree or a stand and be turned round to use the second face, so it works indoors and outdoors. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and suits a new classroom or a school laboratory setup in India where an extra, movable board is needed.

Specifications

Typical Use

Schools without fixed wall boards hang the panel on two hooks or pegs using its eyelets, while those with a permanent board use it as a second writing space for group work, a notice board for the day's homework, or an outdoor board for lessons held under a shelter. Teachers can prepare one face before class — a map outline, a table or a set of questions — and simply turn the board round when it is needed.

Both white slate pencil and chalk write well on the textured paint, and the surface wipes clean with a dry cloth for daily use or a damp cloth for a deeper clean. Let a wet-cleaned board dry before writing on it again. As part of a complete lab setup for schools in India, a panel at the demonstration bench gives teachers somewhere to write readings and results without crossing the room.

Manufacturer

Jain Scientific Equipments Private Limited produces this chalkboard in Ambala, Haryana, and markets it under its ScienceLab trading name to schools, education programmes and distributors in India and international markets. For more about who we are, see the company profile.

Chalk, White (Product Code: SLE/CS/022) is everyday extruded classroom chalk for writing on chalkboards and slates, packed 100 sticks to a box — 90 white for general writing and 10 yellow for headings, key words and emphasis. Each cylindrical stick is about 80mm long and 10mm in diameter, and the non-toxic mix is based on calcium carbonate with talcum powder and bentonite. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a lab consumables supplier in India that also provides the boards and dusters it is used with.

Specifications

Typical Use

Teachers write lesson notes and working in white and switch to a yellow stick to underline the answer, the formula to remember or the day's homework, so key points stand out from across the room. Pupils use the same chalk on slates for letters, sums and quick sketches. To limit breakage, hold the stick near the writing end at a low angle and snap long sticks in half for small hands; keep boxes in a dry cupboard, as chalk absorbs moisture and becomes harder to write with when damp.

Because a single box serves a class for a period of regular use, schools usually order by the carton at the start of term and hand out boxes to each room, keeping a reserve to replenish individual students. Chalk is a routine line item in school supply and school science lab tenders in India, and the estimated 1.5kg box weight helps storekeepers plan shelf space and transport.

Supplier

This chalk is supplied by ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana, which pairs everyday classroom consumables with the teaching equipment it manufactures for schools in India and international markets. Our company profile explains more about the company.

Chalk, Assorted Colors (Product Code: SLE/CS/023) is a box of 100 coloured chalk sticks in 10 different colours, with no white included, for drawing diagrams, maps, charts and labelled sketches on chalkboards and slates. Each non-toxic calcium carbonate stick is cylindrical and extruded, approximately 80mm long and 10mm in diameter. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, one of the school science lab equipment suppliers in India that also stocks everyday classroom consumables.

Specifications

Typical Use

Colour helps pupils separate the parts of a diagram: green for plant tissue and blue for water in a transport diagram, red and blue for arteries and veins, different colours for each side of a triangle or each bar of a chart. Drawing a cell, a flower or the water cycle in several colours turns a quick board sketch into a useful biology teaching aid in India's classrooms, especially where printed charts are not available for every topic. Geography teachers use brown, green and blue for landforms, vegetation and rivers on outline maps.

Keep a colour key in one corner of the board so the meaning of each colour stays consistent through the lesson. Store the box closed and dry, and hand out a few sticks per group rather than the whole box to reduce breakage. For everyday writing, pair this box with white chalk.

Supplier

Coloured chalk is one of the classroom consumables supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company behind the ScienceLab brand, together with the boards and teaching aids it produces for schools in India and international markets.

Drying Rack Glass & Plastic Ware (Product Code: SLE/CL/54) is an upright, plastic-coated wire rack on which freshly washed beakers, flasks, cylinders, bottles and plastic containers are inverted to drain and air-dry beside the sink. It suits wash-up areas in clinical, school and college laboratories, where it is often ordered together with new glassware from a single lab glassware supplier in India. The rack is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

After washing and a final rinse, turn each vessel mouth-down on the rack so that water runs out rather than collecting inside, and hang narrow-necked items such as volumetric flasks and measuring cylinders so they cannot tip over. The plastic coating keeps bare metal away from the glass, which reduces knocks and scratches while wet items are being handled, and it is equally suitable for polypropylene beakers, bottles and sample containers.

Stand the rack on a draining board next to the sink, or fix it to the wall above the sink when bench space is short; water then drips straight into the basin. Keep heavier glassware on the lower part of the rack for stability. Schools and diagnostic labs that buy from a lab plastic ware supplier in India often pair this rack with a wash bottle of distilled water so that the final rinse leaves no mineral spots as the items dry.

Manufacturer

ScienceLab is the brand under which Jain Scientific Equipments Private Limited, based in Ambala, Haryana, makes wash-room, bench and teaching equipment for laboratories. Visit our company profile for background on the business and its product range.

Related Clinical Laboratory Equipment

Items that belong to the same wash-and-dry routine:

• Brush Test Tube — scrubs the inside of tubes and narrow vessels before they go on the rack.
• Wash Bottle LDPE with Narrow Mouth — directs a final rinse of distilled water over cleaned labware.
• Beaker Plastic — everyday plastic beakers that are dried on this rack between uses.
• Cylinder Measuring Plastic — tall measuring cylinders that drain fully when hung upside down.
• Slide Drying Rack — a separate rack for drying stained microscope slides.

See the full Clinical Laboratory category for more labware and bench accessories.

Frequently Asked Questions

What size is the rack?
Approximately 36 x 16 x 65 cm (width x depth x height). Measure the wall or draining area first if space is tight, and contact us if you need exact dimensions for a drawing.

Can it be fixed to a wall?
Yes. It can be used free-standing or wall mounted. Please check with us whether wall fixings are supplied or should be sourced locally for your wall type.

Why is the wire plastic-coated?
The coating separates the metal frame from the glass and plastic items, cushioning contact while wet labware is loaded and unloaded.

Is it suitable for plastic items as well as glass?
Yes. It is described for drying both glass and plastic ware, so beakers, bottles and containers of either material can share the same rack.

Can microscope slides be dried on it?
Slides are better handled in a dedicated slide rack that holds them upright on their edges; this rack is intended for vessels.

Do you ship multiple racks for several lab rooms or overseas?
Yes. We quote for single units, multi-room school orders across India and export consignments to international markets. Send the quantity and destination via our contact page.

A4 Paper, Assorted Colors (Product Code: SLE/CS/025) is a pack of heavyweight coloured paper trimmed to A4 size for art, craft, display and project work in primary and secondary classrooms. Each pack holds 100 sheets of 180 GSM paper in four assorted pastel shades, giving teachers enough colour variety for group activities without opening several different packs. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which also works as a school lab equipment supplier in India for institutions that want classroom materials and science apparatus from one source.

Specifications

Typical Use

Teachers use this paper for making flashcards, cover pages for practical records, labelled diagrams, classroom charts and science-fair display boards. Because the sheets are heavier than everyday writing paper, they hold a fold well, which suits paper models, pop-up cards, simple nets of 3D shapes and folded booklets. The four pastel shades are handy for colour-coding student groups, sorting topics on a notice board, or giving each team in a project its own colour.

For best results, write on the sheets with dark markers or pencils, which stand out clearly against pastel tones. Return unused sheets to the resealable bag and keep the pack flat in a dry cupboard so the edges stay square and the paper does not curl or absorb moisture. Schools ordering other consumables at the same time can add this pack to an enquiry with a lab consumables supplier in India such as ScienceLab to simplify purchasing.

Supplier

This paper pack is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades under the name ScienceLab. Alongside the science apparatus it manufactures, the company sources and packs everyday classroom materials so that schools can furnish a teaching room through a single order. Background on the business is available on the ScienceLab company profile.

Related Classroom Student Items

• Glue, Classroom Use, BOT-170ml — for sticking cut shapes, labels and layered designs
• Scissors, All Purpose, Sharp, 180mm — for cutting the sheets into shapes and strips
• Book, Drawing, A5, Plain, 96 pgs — for sketching a design before transferring it to coloured paper
• Clay, Modelling, Assorted Color — for combining paper backdrops with modelled figures in display projects

See the complete Classroom Student range for stationery, slates and teaching aids.

Frequently Asked Questions

How many sheets of each colour are in one pack?
There are 25 sheets of each of the four pastel colours, making 100 sheets in total.

How thick is the paper?
The paper is 180 GSM, which is noticeably heavier than exercise-book paper and better suited to folding, cutting and mounting.

Can the sheets go through a classroom printer?
That depends on the heaviest paper your printer accepts. Check the media weight rating in the printer manual; if you are unsure, contact us before ordering.

Can I request particular colours?
The standard pack comes in four assorted pastel colours. If your lesson plan needs specific shades, please mention it in your enquiry so we can confirm what is available.

How should the paper be stored?
Keep it sealed in its resealable bag, lying flat in a dry place away from direct sunlight to limit curling and fading.

Do you supply larger quantities for schools and projects?
Yes. We quote for institutional and programme quantities for India and international markets; include the number of packs and the delivery location in your request.

ESR Rack (Product Code: SLE/CL/55) is a complete set-up for measuring erythrocyte sedimentation rate: a stand that holds five graduated tubes still and upright while red blood cells settle through the plasma column. Haematology benches in hospitals and pathology labs, as well as paramedical and MLT training institutes buying lab equipment for college practicals in India, use it for this routine screening test. The set-up is produced in Ambala by Jain Scientific Equipments Pvt Ltd (ScienceLab).

Specifications

Typical Use

Well-mixed anticoagulated blood is drawn into a graduated tube up to the zero mark, and the tube is seated in the stand where the valve holds it without leaking. After the reading interval set by the laboratory's own procedure, the technician reads the height of the clear plasma layer above the settled red cells directly from the millimetre scale, and records it as the ESR for that sample. With five positions, a small batch of patients or a group of students can be tested side by side.

Accurate readings depend on setup: place the rack on a level, vibration-free bench away from direct sunlight, fans and heat sources, and make sure each tube stands truly vertical, since even a slight tilt speeds up sedimentation. Rinse reusable tubes promptly after use. Like other manual laboratory instruments in India's pathology labs, the ESR rack gives consistent results only when these simple precautions are followed.

Manufacturer

Jain Scientific Equipments Private Limited makes this ESR set-up in Ambala, Haryana, and sells it under its trading name ScienceLab to hospitals, pathology laboratories and medical training colleges. Details about the company are on our company profile page.

Related Clinical Laboratory Equipment

Items used before, during and after an ESR test:

• Tube ESR — graduated sedimentation tubes; confirm they match this rack before ordering spares.
• EDTA Vacuum Tube — collects anticoagulated venous blood for haematology testing.
• Blood Specimen Rotator — keeps collected samples evenly mixed until the tube is filled.
• Mechanical Timer 60min — times the sedimentation interval with an audible alert.
• Biohazard Bag — for safe disposal of used disposable tubes and blood-contaminated waste.

More haematology and sample-handling items are listed in our Clinical Laboratory category.

Frequently Asked Questions

How many ESR tests can run at the same time?
Five. The rack provides positions for 5 tubes, each held by its own valve.

Are the tubes part of the set?
The rack is described as a complete set-up with tubes graduated 0 to 200 mm and an internal diameter of 2.6 mm. Please confirm the number of tubes and any spares you need when you ask for a quotation.

Can I use other tubes in this rack?
Only appropriate ESR tubes should be used. The scale length and bore of the tube affect the result, so mismatched tubes can give readings that are not comparable.

Is the stand made of stainless steel or plastic?
It is offered in either stainless steel or plastic. State your preference on the enquiry and we will confirm availability.

Can the rack be used for other blood tests?
No. It is a specific product for the ESR technique only.

Can you provide a calibration certificate for the tubes?
Please discuss any documentation you require with us before ordering through the contact page; we will tell you what can be provided.
