Description
Conical Flask With Stopper 150ml Pyrex
Introduction
The Pyrex Conical Flask Stopper 150ml stands as one of the most trusted pieces of laboratory glassware for scientists, students, and researchers across Bangladesh. Pyrex manufactures this flask from premium Type 1 borosilicate glass, which delivers outstanding resistance to heat, chemicals, and thermal shock. The precision-ground glass stopper seals the flask completely, protecting contents from contamination and evaporation during storage or transit. Whether you work in a university chemistry lab, a pharmaceutical facility, or an industrial quality control unit, this flask meets your daily needs with consistent accuracy and durability.
Product description
Pyrex engineers this 150ml conical flask with a flat, stable base and a tapered conical body that supports safe swirling during mixing and titration. The narrow neck reduces splashing and makes pouring precise and controlled. Users find the smooth interior surface easy to clean, which prevents cross-contamination between experiments. The flask accepts standard laboratory clamps, ring stands, and hot plate setups without any modification.
The included glass stopper fits the flask’s NS 24/29 ground glass joint with a snug, airtight connection. Researchers store reactive reagents, volatile solvents, and biological cultures safely inside without risking spillage or vapour loss. Unlike rubber or silicone stoppers, this glass stopper does not absorb or react with chemical contents, maintaining sample integrity over long storage periods.

We package each flask in protective foam-lined cartons and ship quickly to Dhaka, Chittagong, Sylhet, Rajshahi, and all major districts.
