This listing suits buyers who want one flask of each common shape for a student set. If borosilicate glass, other capacities or a specific neck size matter, the dedicated round-bottom, flat-bottom and conical flask listings give those details.
What Are These Flasks Used For?
The flat-bottomed flask stands on the bench by itself, so it is used for holding and warming liquids and for gas-preparation set-ups in which a thistle funnel and a delivery tube pass through a two-hole cork, as in the preparation of gases in class 10 science. The round-bottomed flask heats evenly and spreads stress around its curved wall, which makes it the standard vessel for boiling, distillation and reflux; it needs a clamp, ring or flask stand to stay upright. The conical (Erlenmeyer) flask narrows towards the neck, so its contents can be swirled during a titration without spilling; it is also used for dissolving solids and preparing culture media. Its graduations show approximate volume only, so measure exact volumes with a pipette, burette or measuring cylinder.
Heat flasks on a wire gauze or in a water bath rather than in a bare flame, never heat a stoppered flask, and let hot glass cool slowly. Because the glass type is not stated here, confirm it with JLab if the flasks will be heated strongly; borosilicate glass handles heating and temperature change much better than soda glass.
What to Specify When Ordering
- Shape and capacity — 250 ml flat bottom, 250 ml round bottom, or 500 ml or 1000 ml graduated conical, with the number of each.
- Glass type — state if you need borosilicate glass.
- Quantity — the minimum order is 10 units; allow spares for breakage.
- Fittings — add rubber corks, a flask stand or clamps to the same enquiry.
Frequently Asked Questions
Which flasks are covered by this listing?
A 250 ml flat-bottomed flask, a 250 ml round-bottomed flask and graduated conical flasks of 500 ml and 1000 ml. Order each shape and size by quantity.
What glass are the flasks made of?
The listing does not state the glass type or neck size. Ask JLab when you enquire; borosilicate round-bottom, flat-bottom and conical flasks are also listed separately.
Are the conical flask graduations accurate?
They are approximate guides for filling. Use a pipette, burette or measuring cylinder when an exact volume is needed.
Why choose a round-bottomed flask?
Its curved wall heats evenly and spreads stress, so it suits boiling, distillation and reflux. It does not stand on its own, so support it with a clamp, ring or flask stand.
Are stoppers included?
Stoppers are not part of this listing. Rubber corks with and without holes are separate items and can be added to the same enquiry.
What details are needed for an export quotation?
The shapes and quantities, destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs, and the tender reference if there is one.
Who manufactures these flasks?
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 laboratory glassware and science apparatus in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The flasks are produced at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy direct from the maker, every flask is inspected visually before dispatch, and repeat orders are handled by the manufacturer. JLab is registered under MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise) and holds Importer-Exporter Code 3317504552.
