Cork Stoppers Manufacturer,Supplier and Exporter in India

Cork Stoppers (Product Code: SLE/CH/196) are brown, wood-material stoppers supplied in an assorted pack of 144, for closing test tubes, boiling tubes, bottles and flasks in the laboratory. Because the sizes are mixed, a single pack lets a teacher find a snug stopper for most of the glassware on the shelf, from a narrow test tube to the neck of a conical flask in school practicals across India. Corks are also easy to bore, so they are widely used to hold a thermometer or glass tube in place. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

In a lower-secondary classroom, corks close test tubes of seeds in germination investigations, seal boiling tubes of water when students compare heating and cooling, and stopper small bottles of dry solids. For apparatus building, a technician bores a cork with a sharp cork borer, pushes a thermometer or delivery tube through, and fits it into a flask to make a simple gas generator or a boiling point set-up. Having an assorted pack on hand means the right size is usually already in the drawer, and a split cork is one of the easiest lab consumables to swap out mid-lesson.

Pick a cork that enters about a third to half of its length into the neck before it grips. Wet the cork slightly before boring, bore from the narrow end, and ease glass through with a twisting motion while protecting your hand. Store corks in a dry container so they do not shrink or go mouldy.

Frequently Asked Questions

How many stoppers are in a pack?
Each pack contains 144 assorted cork stoppers.

Which sizes are included?
The pack is an assortment; the exact size mix is not listed here. If you need particular neck sizes, send them through the contact page and we will confirm what can be supplied.

Can holes be bored in them?
Yes. Corks bore easily with a sharp cork borer, which is why they are often used to mount thermometers and glass tubing.

When is a rubber stopper a better choice?
For airtight or vacuum joints, or where liquids would soak into the cork, a rubber stopper usually performs better. Corks suit general closures and easily bored fittings.

How should corks be stored?
In a closed, dry container away from heat, so they keep their shape and do not absorb moisture.

Do you supply larger quantities?
Yes. Tell us how many packs of 144 you need and the delivery location in India or abroad for a quotation.
