Droppers with Rubber Bulb Manufacturer,Supplier and Exporter in India

Droppers with Rubber Bulb (Product Code: SCL-677/085) are glass dropper assemblies that draw up and release liquid a drop at a time when the rubber bulb is squeezed and released. The dropper is made of borosilicate glass, and the assembly is fine ribbed, child-resistant and fitted with a tamper-evident seal, which helps keep stored reagents secure and shows whether a container has been opened. Chemistry and biology teachers rely on them for dispensing small amounts of indicators, stains and test reagents where pouring would be too coarse. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

A dropper is the simplest way to add an exact number of drops: two or three drops of phenolphthalein or methyl orange into a titration flask, a drop of universal indicator solution on a glazed tile for a quick pH check, or a single drop of stain onto a slide in a biology practical. In qualitative analysis, students add a test reagent drop by drop and watch for the first sign of a precipitate or colour change, which a pouring bottle cannot control as finely.

Squeeze the bulb before dipping the tip into the liquid, then release slowly to fill. Keep the dropper pointing downwards once it holds liquid, because liquid that runs back into the bulb shortens the life of the rubber and can contaminate the next reagent. Use a separate dropper for each solution, rinse by drawing up and expelling distilled water a few times after use, and keep the rubber away from organic solvents and heat.

Frequently Asked Questions

What are the droppers made of?
The dropper is borosilicate glass and the bulb is rubber.

What does the 110 ml capacity refer to?
110 ml is the capacity listed for this item. If you need the dropper to match particular bottles, send their details through the contact page and we will confirm suitability before you order.

What do child-resistant and tamper-evident mean here?
The fine-ribbed assembly is designed to be child-resistant, and the tamper-evident seal shows whether it has been opened, which is useful for stored reagents.

Can one dropper be shared between reagents?
It is better not to. Use one dropper per solution to avoid cross-contamination, and rinse it thoroughly if it must be reused.

How do I look after the rubber bulb?
Keep liquid out of the bulb, avoid organic solvents and heat, and store the droppers in a cool, dry place.

Can you supply droppers in bulk for several labs or for export?
Yes. ScienceLab supplies institutions and dealers in India and international markets; tell us the quantity and destination.
