150ml Borosilicate Glass Conical Laboratory Flask

150ml Borosilicate Glass Conical Laboratory Flask – Narrow Neck

The 150ml Borosilicate Glass Conical Laboratory Flask from Labglass is a narrow neck Conical (Erlenmeyer) flask for everyday mixing, heating and culture work in the laboratory. This borosilicate conical flask gives you a durable, heat resistant vessel with clear white graduations for quick volume checks.

Manufactured from high quality borosilicate 3.3 glass, the flask offers low thermal expansion and very good chemical resistance, so it is suitable for repeated heating and cooling cycles in teaching, QC and research labs. The conical shape promotes efficient swirling and mixing, whilst the narrow neck helps reduce splashes and supports the use of stoppers or cotton wool plugs. Uniform wall thickness improves mechanical strength and heat distribution during use over burners, hotplates or in water baths. White enamel graduations at 25mL intervals indicate approximate volume, helping you set up reactions or media batches with confidence. The reinforced rim provides improved impact strength at the mouth, and the flask is autoclavable at 121 °C for sterile work.

Practical Applications
– Preparing and mixing culture media, buffer solutions and reagents
– Carrying out titrations, extractions and general reaction set ups
– Swirling and incubating microbiological or cell culture liquids with closures or plugs
– Use in teaching laboratories for volumetric exercises and demonstration work
– Holding samples or fractions during analytical and QC workflows
