Test Tube Rim Glass 18mm 150mm

This pack supplies 72 clear borosilicate glass test tubes with a rim, each 18 mm in body diameter and 150 mm in overall height. The tubes hold a nominal 25 mL (0.57 oz) and are autoclavable for repeated sterilisation. They are intended for general liquid handling and centrifugation tasks in laboratory settings.

Suits labs needing bulk disposable glassware

Technicians who require graduated markings or supplied closures should look elsewhere because these tubes are ungraduated and ship without caps. The absence of a maximum relative centrifugal force rating also means users must verify compatibility with their specific rotor speeds before centrifuging.

Pack of 72 changes workflow planning

The 72-piece quantity reduces reorder frequency for high-throughput environments such as teaching labs or routine QC stations. Borosilicate construction allows direct autoclaving, so tubes can be sterilised in batches without transferring to separate vessels.

Questions about this item

What diameter test-tube rack holes do I need for these 18 mm borosilicate tubes?

Choose a rack with 18 mm diameter holes so the 18 mm body of each tube sits securely without wobble.

Can I autoclave these clear glass tubes alongside older plastic tubes that are not autoclavable?

Only the borosilicate glass tubes are autoclavable; remove any non-autoclavable plastic tubes before running the cycle.

How do I confirm the 25 mL nominal capacity is accurate after autoclaving?

Fill a tube with 25 mL of water — the liquid should reach the expected level on the clear, ungraduated body.
