Applications and Experiments for the Screw Cap Erlenmeyer Flask
A screw-cap Erlenmeyer flask is chosen when a solution or medium must be mixed and then kept closed, whether on the shelf, in transit or through autoclaving of the cap. The sloping walls allow swirling without spills, making it useful borosilicate laboratory glassware in India for college and research benches.
- B.Sc. microbiology and biotechnology: preparing and storing culture media and buffers.
- Chemistry practicals: keeping standard solutions closed between titration sessions.
- Research and quality labs: holding samples securely during storage and transport.
Loosen the cap before autoclaving so steam can vent, and let the flask cool before tightening it again.

Frequently Asked Questions
Can the screw cap be autoclaved?
Yes. The polyethylene screw cap is autoclavable, and a PTFE liner is fitted inside it. Keep the cap loose during the cycle so pressure does not build up in the flask.
Which capacities are available?
Five sizes are listed: 50 and 100 ml with thread size 25, and 250, 500 and 1000 ml with thread size 32. Diameters run from 51 mm to 131 mm.
What glass is the flask made from?
It is made from heat-resistant borosilicate glass, which handles heating and ordinary laboratory temperature changes better than soda-lime glass.
Who supplies this flask?
The flask is supplied by Science Lab Supplies from Ambala, India, for single orders, laboratory stock and tender quantities.
