What Are Rubber Stoppers Used For?
A solid stopper closes a test tube or flask so that its contents can be shaken, stored for a while or kept from spilling. A one-hole stopper carries a single glass tube or a thermometer, and a two-hole stopper takes two tubes at once — for example a thistle funnel and a delivery tube in a gas-preparation flask.
Frequently Asked Questions
Will these stoppers fit plastic test tubes?
Yes. They suit glass or plastic test tubes as well as Erlenmeyer flasks; give the tube or flask size you use so that the right stopper size is quoted.
Can a cork borer be quoted with the stoppers?
Yes. Cork borers and other stoppers are separate catalogue items, linked below, and can be added to the same enquiry.
What should an export enquiry include?
The quantity of each hole option and size, the destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling needs, and the tender reference for tender purchases.
Who manufactures these rubber stoppers?
JLab produces them in Ambala, Haryana, and quotes for them directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a chemistry lab equipment and consumables manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The stoppers come from its own works rather than a trader, so schools, colleges, dealers and importers buy them factory-direct. JLab exports worldwide and ships to buyers in every region — for example Latvia in Northern Europe, South Korea in East Asia, Zambia in East Africa, Trinidad and Tobago in Central America and the Caribbean, and the UAE in the Middle East.
Cork Borers and Other Stoppers
- Cork Borer (Brass) — brass-tube borers for cutting clean holes in corks and rubber stoppers.
- Silicon Rubber Cork — silicone rubber stopper suitable for autoclaving.
