The plated model is listed with a clearing rod and a stated maximum diameter, and the thick-pipe model with a heavier handle; ask JLab if your choice depends on a detail that none of the listings gives.
What Is a Brass Cork Borer Used For?
Many practical set-ups need a glass tube, thermometer or delivery tube to pass through a sealed cork or rubber stopper — for example the gas-preparation and simple distillation apparatus used in school chemistry practicals. A cork borer cuts that hole cleanly so the tube fits snugly and the seal holds. Pick a borer slightly smaller than the outside diameter of the tube, wet the cutting edge with water or glycerine when boring rubber, rest the stopper on a wooden block and bore from its narrow end with a steady twisting motion rather than pushing straight down. Keep the edges sharp with a cork borer sharpener and wipe the tubes dry after use. It is a small but frequently used item in any chemistry lab equipment list for schools in India and abroad.
What to Specify When Ordering
- Set size — 6, 8 or 12 borers; ask for the diameters in each set if you need to match particular tubing and stoppers.
- Quantity — the minimum order is 10 units (sets); schools often plan one set per prep room plus one for each practical group.
- Corks and sharpener — add rubber corks and a cork borer sharpener to the same enquiry so the borers can be used and maintained from day one.
Frequently Asked Questions
What is a cork borer used for?
It cuts neat, uniform holes in corks and rubber stoppers so that glass tubes can be inserted for laboratory set-ups. This listing is a set of brass-tube borers rather than a single borer.
Which set sizes can I order, and what diameters do they cover?
You can order sets of 6, 8 or 12 borers. The listing does not state the diameter of each borer, so ask JLab to confirm the sizes in your chosen set before ordering if they must match particular tubing or stoppers.
How do I choose the right borer for a glass tube?
Use a borer slightly smaller than the outside diameter of the tube. The cork or rubber closes in a little after boring, so the stopper grips the tube and seals around it.
Are corks, stoppers or a sharpener included?
No. This listing covers the borer set only. Rubber corks with and without holes and a cork borer sharpener are separate items, linked below, and can be added to the same enquiry.
Who manufactures this cork borer set?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a school and college laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. These cork borers come from JLab’s own works, not from a trading house, so schools, colleges, dealers and importers buy them factory-direct; every set is visually inspected before it is packed, and repeat orders are handled by the manufacturer itself. JLab exports worldwide and ships to buyers in every region — for example Belgium in Western Europe, Kyrgyzstan in Central Asia, Bolivia in South America, Japan in East Asia and Sierra Leone in West Africa. Institutions buying through tenders can find details on the JLab lab tenders page.
Corks, Stoppers and Borer Care
- Cork Borer Sharpener — a brass cone with a hinged steel blade for restoring the cutting edge of cork borers.
- Rubber Corks (without Holes) — solid rubber stoppers that can be bored to suit your tubing.
- Rubber Corks (with One Hole) — ready-bored stoppers for a single glass tube or thermometer.
- Rubber Corks (with Two Holes) — stoppers bored twice, for example for a thistle funnel and a delivery tube.
