Glass Filtering Flasks meet ASTM E-1406 Type II, Class 1 Specifications for Classification, Design, Capacity & Dimensions, and Markings.
These filtering flasks feature heavy-duty rims to reduce chipping, white, permanent graduations, and large marking squares. Made from high-quality borosilicate tubing with a low coefficient of expansion. Borosilicate tubing also provides uniform wall thickness resulting in the optimum balance between thermal shock resistance and mechanical strength.
Tubulation outside diameter is 10mm. Accuracy: ±5% of full capacity
