The 21 x 26.5 x 27.5 mm size appears in the solid, one-hole and two-hole ranges, which makes it easy to match a closed stopper with a bored one for the same vessel. Choose the solid stopper when nothing has to pass through it.
What Is the Solid Rubber Stopper Used For?
A solid stopper simply closes a vessel: it stops a test tube spilling when it is shaken, keeps a prepared solution from evaporating or picking up dust between lessons, and seals a flask when an experiment needs a closed container. Because the stopper is tapered — narrower at the bottom than at the top — it wedges into the neck and seals as it is pushed in. To pick a size, the bottom diameter should be a little smaller than the inside of the neck and the top diameter larger than it. Rubber stoppers like these are used in school chemistry and biology practicals from middle school to class 12, and in college teaching labs.
What to Specify When Ordering
- Size — quote the bottom x top x length figures from the table for each size you need.
- Quantity of each size.
- One-hole or two-hole stoppers, or a cork borer — separate items that can be quoted on the same enquiry.
Frequently Asked Questions
How do I choose the right size?
Measure the inside of the tube or flask neck. The bottom figure of the stopper should be slightly smaller than that and the top figure larger, so the taper seals part-way in.
Does it have a hole for a glass tube or thermometer?
No, it is solid. JLab’s Rubber Stopper (one hole) and 2 Hole Rubber Stopper are the bored versions.
What information is needed for an export quotation?
The sizes and quantity of each, the destination country and port or city, your delivery terms (for example FOB or CIF), any packing or labelling needs and a tender reference if there is one.
Who manufactures the Solid Rubber Stopper?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory consumables and school science equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The stoppers are made at JLab’s own works rather than bought in from a trader, so schools, colleges, dealers and importers buy direct from the maker, and repeat orders in the same sizes come from the same manufacturer. JLab exports worldwide and ships to buyers in every region — Argentina in South America, Taiwan in East Asia, Austria in Western Europe, Tonga in Oceania and Malta in Southern Europe are some examples.
Bored Corks and Cork Tools
- Rubber Corks (with One Hole) — bored rubber stoppers that let a single glass tube or thermometer pass through, in packs of 100.
- Cork Borer (brass, with clearing rod) — plated brass cutting tubes for boring holes in corks and rubber stoppers.
Browse the General Lab Equipment range or the wider Laboratory Supplies section for more.
