Rubber Cork for Hypsometer
Rubber Cork for Hypsometer (Product Code: SCL-304/050) is a red rubber bung used to seal the thermometer and tube openings of a hypsometer during thermometry experiments in physics laboratories. Lab staff order it as a spare when the original bungs harden, crack or go missing, and it is offered as an assorted lot. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, from its range of physics instruments for schools and colleges.

What Is the Rubber Cork for Hypsometer Used For?
A hypsometer depends on tight bungs: one holds the thermometer under test in the lid tubule and another seals the manometric tube in its side tubulure. If a bung is cracked or loose, steam escapes and both the pressure check and the fixed-point reading lose their meaning. These rubber corks replace worn or lost bungs so the apparatus can go straight back into use.
When a hole is needed, bore it with a sharp cork borer of the right size. Wet the thermometer with a little water or glycerine, hold it close to the cork with a cloth and ease it through with a gentle twist; never force glass through a tight hole. Keep spare corks away from heat and oil, which make rubber harden or swell.
What to Specify When Ordering
- The openings the corks must fit: the lid tubule for the thermometer, the manometric tube neck, or both
- The number of corks needed per hypsometer and per lab
- Whether a complete Hypsometer or other physics apparatus should be quoted in the same order
Supplier
Jain Scientific Equipments Private Limited trades as ScienceLab and supplies these rubber corks from Ambala, Haryana, as spares for the physics apparatus it offers schools and colleges. Ordering corks together with the hypsometer keeps a thermometry set complete, and the same enquiry can cover other consumables. Company details are on the ScienceLab company profile.

Frequently Asked Questions
What is the Rubber Cork for Hypsometer made of?
The Rubber Cork for Hypsometer is made of red rubber. Rubber grips the glass of a thermometer or tube firmly and seals the opening against steam, which suits the conditions inside a hypsometer during a boiling-point check.
Is the Rubber Cork for Hypsometer one fixed size?
No, the Rubber Cork for Hypsometer is offered as an assorted lot rather than one fixed size. Tell us which hypsometer openings the corks must fit when you enquire, and the assortment for your order will be confirmed in the quotation.
Does the Rubber Cork for Hypsometer come with holes?
Hole details for the Rubber Cork for Hypsometer are not listed, so please confirm them through the ScienceLab contact page. Labs that bore their own holes should use a sharp cork borer matched to the thermometer so the fit stays steam-tight.
How do I fit a thermometer into the rubber cork safely?
Wet the thermometer with water or glycerine, hold it near the Rubber Cork for Hypsometer with a cloth and ease it through with a gentle twisting motion. Never push hard on glass, because a snapped thermometer can cause deep cuts.
Who supplies the Rubber Cork for Hypsometer?
The Rubber Cork for Hypsometer is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges and dealers in India and international markets, alongside the hypsometer and other physics lab apparatus.
What does a quotation for the rubber corks need?
A quotation for the Rubber Cork for Hypsometer needs the product code SCL-304/050, the number of corks, the openings they must fit and the delivery location. Add any hypsometers or other spares to the same enquiry to have them quoted together.
