Precision lab glassware for analytical work

This pack supplies twelve Class A volumetric flasks made from clear borosilicate glass. Each unit delivers a certified 10 mL capacity with a tight 0.02 mL tolerance. The canted neck and included 10/13 glass stopper support accurate meniscus reading and secure sealing. The flasks are autoclavable and meet USP Type II specifications for demanding laboratory protocols.

Verify stopper fit and neck clearance

Confirm that your existing 10/13 stopper inventory matches the supplied ground-glass joints before ordering. Check that the 90 mm overall height clears any shelving, heating blocks or automated handler grips in your workflow. The narrow mouth design requires a suitable funnel or pipette tip for clean filling without spillage.

Thermal stability and cleaning profile

Borosilicate construction withstands repeated autoclave cycles without dimensional drift that would affect the Class A tolerance. Glass stoppers eliminate polymer degradation and avoid leaching during high-temperature sterilisation. The smooth, non-porous surface resists residue build-up and cleans quickly with standard laboratory detergents. No powered components are present, so the kit adds no electrical load or acoustic noise to the bench.

Questions about this item

What does the pack of 12 flasks include and what must be bought separately?

The pack contains 12 clear glass volumetric flasks, each supplied with a glass stopper. No additional closures or accessories are required for standard volumetric use.

When should I choose the 10 mL Class A flasks over other capacities?

Choose the 10 mL size when your protocol calls for preparing or diluting small, precise volumes with a 0.02 mL tolerance; larger capacities have different tolerances and are not interchangeable for this volume.

What does the 0.02 mL tolerance mean when I use the flask in the lab?

When filled to the calibration mark at the reference temperature, the actual volume will be within ±0.02 mL of 10 mL, meeting Class A accuracy for analytical work.
