Vacuum Flask Manufacturer,Supplier and Exporter in India
Product Code : EL-LS-4987
Jlab Export is a leading Vacuum Flask Manufacturer,and suppliers in India
Vacuum Flask (code EL-LS-4987) is an insulated flask used in laboratories to keep stored liquids close to the temperature they had when they were poured in — hot substances stay hot and cold substances stay cold for a long time. It is part of JLab’s range of laboratory supplies and is useful wherever hot water, chilled water or ice has to be kept ready for an experiment. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is a Vacuum Flask Used For?
A vacuum flask has a vacuum between its inner and outer walls. With almost no air in that gap, heat can hardly pass across it by conduction or convection, so a hot liquid inside loses heat slowly and a cold one gains heat slowly. In the laboratory this keeps hot water, ice-cold water or crushed ice ready for experiments that need a liquid near a steady temperature, and it lets samples be carried between rooms without warming up or cooling down quickly. The flask is also the standard example used in school physics lessons on conduction, convection and radiation, so a working flask makes a useful classroom demonstration.
What to Specify When Ordering
- Capacity — state the capacity you need in your enquiry.
- Quantity — the minimum order is 10 units.
- Heat experiment items — laboratory thermometers, calorimeters and thermometer holders are separate catalogue items that can be quoted on the same enquiry.
Frequently Asked Questions
How does a vacuum flask keep liquids hot or cold?
The vacuum between its two walls greatly reduces heat flow by conduction and convection, so the temperature of the liquid inside changes only slowly.
Does it keep liquids at exactly the same temperature?
Not indefinitely. A vacuum flask slows heat transfer rather than stopping it, so hot substances stay hot and cold substances stay cold for a long time, but the contents still drift towards room temperature eventually.
What information is needed for an export quotation?
Please give the quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling requirements, and the tender reference if applicable.
Who manufactures this vacuum flask?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of laboratory supplies and teaching equipment, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. The vacuum flask is made at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy direct from the factory, every flask is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Honduras in Central America and the Caribbean, Nepal in South Asia, Brunei in Southeast Asia, Australia in Oceania and Chad in Central Africa. See the JLab lab tenders page for tender enquiries.
Thermometers and Heat Apparatus
- Laboratory Thermometer — a liquid-in-glass thermometer for laboratory use.
- Copper Calorimeter — a jointless copper calorimeter with an aluminium outer casing, for specific heat capacity experiments.
- Calorimeter — a metal calorimeter vessel for method-of-mixtures, latent-heat and cooling experiments.
