Choose this listing when you want a stirring-type mercury thermometer or a white-backed red spirit thermometer and can confirm the scale with JLab. If you need a range that is already fully specified, the general-purpose mercury thermometer and the environmentally safe liquid thermometer give theirs on their own pages.
What Are Laboratory Thermometers Used For?
Glass thermometers measure the temperature of water baths, solutions and reaction mixtures. In class 9 science they are used to find the melting point of ice and the boiling point of water and to plot heating and cooling curves; in class 10 they show whether a reaction gives out or takes in heat; and in college labs they follow calorimetry and rate experiments. The coloured back strip behind the bore makes the thin liquid thread easier to read against the scale.
For a correct reading, keep the bulb fully in the liquid without touching the wall or bottom of the vessel, wait until the reading is steady, and read at eye level. A stirring thermometer is meant to be moved through the liquid while it is read, but it is still glass, so stir gently. The red spirit version contains no mercury, which matters because many countries and schools restrict mercury-filled instruments; if a mercury thermometer breaks, keep students away and follow your school’s mercury spill procedure.
What to Specify When Ordering
- Type — mercury-filled stirring thermometer (yellow back) or red spirit thermometer (white back), and how many of each.
- Scale — the temperature range, graduation and overall length you need, so JLab can confirm the matching size.
- Quantity — the minimum order is 10 units; allow spares, as thermometers are often broken in student practicals.
- Clamps — add a thermometer clamp if the thermometer must be held in a stand.
Frequently Asked Questions
Which thermometers does this listing include?
A yellow-backed, mercury-filled stirring thermometer listed in two sizes, and a white-backed thermometer filled with red spirit.
What temperature range and length are they?
The listing prints the sizes as 10x50x300 mm, 10x100x300 mm and 10x110x305 mm, with the range and length run together. Because the figures cannot be read with certainty, state the range, graduation and length you need and JLab will confirm the match before quoting.
Should I choose mercury or red spirit?
Choose red spirit where mercury is restricted or where breakages are likely, as it contains no mercury. Mercury thermometers are still chosen by some labs; check your local rules first.
What does “stirring” mean here?
It is a stirring-type thermometer, meant to be moved through a liquid while the temperature is read, as in calorimetry. Stir gently all the same, because the stem and bulb are glass.
Is a thermometer clamp included?
No. The thermometers are sold individually; the thermometer clamp is a separate item that can be added to the same enquiry.
What should an export enquiry include?
The type and quantity of each thermometer, the scale you need, the destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling instructions, and a tender reference if there is one.
Who manufactures these thermometers?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes them at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of school and college lab instruments in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. These thermometers leave JLab’s own works rather than a trader’s warehouse, so schools, colleges, dealers and importers buy them factory-direct, each one is visually inspected before dispatch, and repeat orders are handled by the manufacturer. The company holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise) and Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example South Africa in Southern Africa, Brazil in South America, Afghanistan in South Asia, Poland in Eastern Europe and Kazakhstan in Central Asia. Tender information is on the JLab lab tenders page.
