50ml Clear Borosilicate Glass Rimless Test Tube (Pk 50)

50ml Clear Borosilicate Glass Rimless Test Tube – 150x24mm

The 50mL clear borosilicate 3.3 rimless test tube is a large capacity, light-wall glass test tube for mixing, heating and storing bigger sample volumes in your lab. This 150 × 24mm borosilicate glass test tube provides you with strong, chemically resistant glassware that is easy to handle in standard racks and clamps.

Constructed from borosilicate glass 3.3 that meets key laboratory glass standards, the tube resists thermal shock and attack from most routine reagents. The light wall design promotes efficient heating in water baths, ovens or over a flame, whilst the smooth rimless top makes pouring and cleaning straightforward. Fire polished ends work well with rubber stoppers, cotton wool plugs or polypropylene test tube stoppers, so you can secure your samples during mixing, incubation or storage. Autoclavability at 121 °C allows you to sterilise the tube between uses, which is particularly useful in microbiology, cell culture and teaching environments.

Practical Applications
– Mixing and heating larger reaction volumes, culture media or buffer solutions
– Incubating biological or microbiological samples in 24mm tube racks with suitable closures
