Volumetric Flask, Class A

Volumetric Flask, Class A from PX Scientific Goods, manufactured in Type I Class A borosilicate 3.3 glass and supplied for routine laboratory and light industrial use. Uniform wall thickness and a low coefficient of expansion (3.3 × 10⁻⁶ K⁻¹) allow direct heating and rapid cooling without crazing.

Available in 3 options: 50 mL, 250 mL, 1000 mL. Each item is inspected before dispatch and packed to survive normal carrier handling. Dimensional and volumetric figures conform to ISO 3585 / ASTM E438 Type I Class A; where a tolerance class is stated it applies to the item as supplied, at 20 °C.

Care and handling

Autoclavable at 121 °C. Hand wash or use a laboratory-grade glassware detergent; avoid abrasive scouring, which creates nucleation sites and shortens service life.
