Rimmed borosilicate test tubes, 72 pack
These clear glass tubes measure 10 mm in diameter and 75 mm in height. Each tube holds 3 mL or .03 oz of liquid. The Type I borosilicate glass resists thermal shock and chemical attack. They are supplied without closures or graduations.
Simple to use in standard racks and holders
The smooth rim allows quick pouring and easy insertion into common 10 mm tube racks. Without a screw cap or snap lid there is no threading to cross or gasket to lose. Autoclaving is straightforward because no plastic parts are present. Breakage is the main risk if tubes are dropped or knocked together.
3 mL capacity suits small-volume work
The nominal 3 mL volume handles typical aliquots for centrifugation, liquid handling and general lab procedures. Headroom above the liquid is limited, so vigorous mixing or boiling can cause spillover. Larger sample volumes will require a different tube size.

Questions about this item
How can I confirm the borosilicate glass tubes are performing correctly after autoclaving?
After autoclaving, inspect each tube for cracks or cloudiness; clear, intact Type I borosilicate glass with a 10 mm diameter and 75 mm height indicates it withstood the cycle.
What does the pack of 72 include and what must I purchase separately?
The pack contains 72 clear, non-graduated test tubes with rims made of Type I borosilicate glass; closures are not included and must be bought separately.
Which capacity should I choose for liquid handling tasks needing roughly 3 mL per tube?
Each tube has a nominal capacity of 3 mL (0.03 oz), so this single listed size suits workflows requiring approximately that volume per tube.
