Product Code : SCL-CL-11897
Metal File for Rubber Stoppers (SKU SCL-CL-11897) is a tool with a convenient handle and six removable heads, sized from 3 mm to 20 mm, for working the holes in rubber stoppers. It suits preparation rooms that fit stoppers for delivery tubes, thermometers and gas-preparation set-ups in school, college and technician-training labs. Science Lab Supplies, working from Ambala in India, can quote the file for schools, colleges, tender contractors and distributors.
Specifications
Each row of the table below covers one fact about this six-head stopper file. In short, a single handle takes six interchangeable heads from 3 mm to 20 mm, so one tool can be matched to small and large holes in rubber stoppers, and it is built for durable, repeated use in a laboratory.

Applications and Experiments for the Rubber Stopper File
A rubber stopper file lets a technician shape or enlarge the hole in a stopper so that a glass tube, thermometer or funnel stem fits snugly and the joint does not leak. It supports the glassware set-ups found in CBSE/NCERT chemistry practicals, B.Sc. chemistry labs and laboratory-technician training.
- Class 10 chemistry: fitting delivery tubes for preparing and collecting gases, for example with the Simple Gas Preparation Kit.
- Class 11–12 practicals: sizing a stopper hole for one of the Laboratory Thermometers in boiling-point work.
- Distillation set-ups: matching stopper holes to the flask and condenser of the Apparatus for Distilling Liquids.
- Lab preparation: refreshing worn or uneven holes so stoppers can be reused.
Choose the head closest to the required diameter, work the hole gradually and test the fit often, because rubber cannot be put back once removed. Wetting the glass before pushing it through the finished hole helps it slide in safely.
Standard Scope of Supply
Each Metal File for Rubber Stoppers comes as one handle with six removable heads in sizes from 3 mm to 20 mm, matching the table above. Rubber stoppers, glass tubing and thermometers can be added to the same quotation if the preparation room needs them as well.
Packing, MOQ and Lead Time
Order one file for the preparation room or several for a college with many benches; the quotation you receive lists packing, delivery time and price for that exact quantity. Stoppers in matching sizes can be added so the lab receives tools and consumables together.
With an Importer-Exporter Code in place, Science Lab Supplies is able to ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. If the file is part of a wider preparation-room order, describe it on the contact page, gather every item in the enquiry cart, or turn to the lab tender page when a formal bid is involved.
Frequently Asked Questions
How many heads come with the file?
Six. The removable heads cover sizes from 3 mm to 20 mm, so the same handle can serve narrow thermometer holes and wider openings for glass tubes or funnel stems.
Can the file be used on stoppers other than rubber?
It is made for rubber stoppers. If you need to work cork or another material, ask through the contact page before ordering so the quotation can confirm what suits it.
Who provides the Metal File for Rubber Stoppers?
Buyers obtain it from Science Lab Supplies in Ambala, India, where it sits in the chemistry lab equipment in India range and can be priced as a single tool or in quantity for schools, colleges and distributors.
Is the file meant for occasional or regular use?
It is suitable for repeated use, with high durability, a long life and a convenient handle, so it can serve routine stopper preparation over many terms.
