Block Heater, Round Bottom Flasks Manufacturer,Supplier and Exporter in India

Block Heater, Round Bottom Flasks (Product Code: SLE/LI/11) is a reaction block used to hold and heat a single 100 ml round bottom flask on a hotplate or magnetic stirrer in chemistry teaching and research laboratories. Organic chemistry students and technicians use it for reflux and warming work, where a round-bottomed flask cannot sit securely on a flat plate. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Round Bottom Flask Block Heater Used For?

A round-bottomed flask touches a flat hotplate at only a small point, so heating it directly is slow and uneven. The block heater surrounds the lower part of a 100 ml flask and carries heat from the plate into the glass, giving steadier warming for reflux, simple distillation, dissolving solids and small-scale reactions. Used on a hot plate magnetic stirrer, a stir bar can mix the flask contents while they heat.

Centre the block on the plate, seat the flask fully before heating and still clamp the neck to a stand — the block supports the flask but is not a substitute for a clamp. Raise the plate temperature gradually, and handle the block with heat-resistant gloves, since it stays hot for some time after the plate is switched off.

What to Specify When Ordering

• The number of blocks per laboratory — each block takes one 100 ml flask.
• The hotplate or magnetic stirrer model it will sit on, so plate size can be checked.
• Whether 100 ml round bottom flasks should be quoted with the blocks.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this block heater. The company makes it at its own licensed factory at Saha, Ambala, Haryana, and supplies it factory-direct to schools, colleges, institutions, dealers and importers instead of routing orders through a trader.

The company is a registered MSME (Udyam UDYAM-HR-01-0003714), and its export consignments move under Importer-Exporter Code AAECJ8618A issued by the DGFT. For repeat orders or replacement blocks, ask the manufacturer directly; company details are on our company profile.

Frequently Asked Questions

What size flask does the Block Heater, Round Bottom Flasks hold?
The Block Heater, Round Bottom Flasks holds one 100 ml round bottom flask. It is a single-flask reaction block, so laboratories that heat several flasks at the same time normally order one block for each hotplate position.

Can the block heater be used on a magnetic stirrer?
Yes. The Block Heater, Round Bottom Flasks is suitable for hotplates and magnetic stirrers. On a hotplate stirrer, a magnetic stir bar in the 100 ml flask can mix the contents while the block transfers heat to the glass.

Who manufactures the Block Heater, Round Bottom Flasks?
The Block Heater, Round Bottom Flasks is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations and repeat orders are handled directly by the manufacturer.

Does the block heater replace a clamp and stand?
No. The Block Heater, Round Bottom Flasks supports and heats the base of a 100 ml flask, but the flask neck should still be clamped to a retort stand, particularly when a condenser is fitted for reflux work.

Are round bottom flasks included with the block heater?
The listing for the Block Heater, Round Bottom Flasks covers the reaction block for one 100 ml flask. If you need flasks as well, add them to your enquiry and the block and glassware can be quoted together.
