Flask Erlenmeyer with Screw Cap
Product Code : LSK-LF-10417
Flask Erlenmeyer with Screw Cap (SKU LSK-LF-10417) is a conical flask in heat-resistant borosilicate glass, closed by an autoclavable polyethylene screw cap with a PTFE liner. It comes in five sizes from 50 to 1000 ml. It suits chemistry, microbiology and biotechnology benches where solutions and media are prepared, stored and carried. Colleges, universities, training institutes, tender contractors and distributors can order it through Science Lab Supplies, with every quotation drawn up in Ambala, India.
Specifications
The table lists every size, thread and diameter of the screw-cap Erlenmeyer flask. In short, it keeps the familiar conical shape with a threaded neck in place of a plain rim: the 50 and 100 ml sizes carry thread size 25, the larger three thread size 32, and the PTFE liner sits between cap and rim.

Applications and Experiments for the Screw Cap Erlenmeyer Flask
A screw-cap Erlenmeyer flask suits work where 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, with the caps sterilised in a Hand Wheel Vertical Pulse Vacuum Autoclave.
- Chemistry practicals: keeping standard solutions closed between titration sessions with a Borosilicate Glass Burette 50ml.
- 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.
Standard Scope of Supply
Each flask is supplied with its polyethylene screw cap and PTFE liner, in the capacity you order: 50, 100, 250, 500 or 1000 ml. Mixed sizes can be combined on one order, and the quotation lists the quantity of each capacity together with its thread size.
Packing, MOQ and Lead Time
Tell us the capacities and numbers you need, from a few flasks for a research group to a stock for a teaching lab, and the quotation will state packing, delivery time and price for that order. Other flasks and glassware can be added so everything arrives together.
With an Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. A mixed-size flask order can be sent as a message from the contact page or built up in the enquiry cart, and the lab tender page explains how tender documents are handled.
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?
There are five sizes: 50 and 100 ml with thread size 25, and 250, 500 and 1000 ml with thread size 32. Diameters run from 51 mm for the smallest to 131 mm for the 1000 ml flask.
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?
Orders are quoted from Ambala, India, by Science Lab Supplies, whether you need one flask, a stock of mixed capacities for a teaching lab, or a tender quantity with other glassware.
