Class A Volumetric Flask 1000 mL

This pair of Class A volumetric flasks delivers 1000 mL capacity with a 0.40 mL tolerance for precise analytical work. Each flask stands 320 mm tall with a canted neck and glass stopper sized 19/17. Clear borosilicate glass construction supports autoclaving and general laboratory use.

Capacity and headroom for 1 L volumes

The 1000 mL (33.8 fl oz) capacity suits standard solution preparation and dilution series up to one litre. Class A tolerance of 0.40 mL ensures reliability for volumetric analysis. The narrow mouth and canted neck aid controlled pouring, while the included glass stoppers seal securely for storage or mixing.

Replaces lower-grade or single flasks

Laboratories using Class B glassware or single flasks gain improved accuracy and workflow redundancy with this matched pair. The upgrade is worthwhile when traceable volumetric precision is required for quality control or method validation. Not suited for applications needing graduated readings along the neck or sterile-out-of-box vessels.

Questions about this item

Will the 19/17 glass stopper fit the existing narrow-neck flasks on our shelf?

The 19/17 stopper is sized for the canted neck on these Class A flasks; other narrow-neck flasks use different joint sizes, so the stopper will not interchange.

How do I confirm the 0.40 mL tolerance is being met after autoclaving?

Fill the flask to the 1000 mL mark with distilled water at 20 °C and weigh it; the mass should correspond to 1000 mL ± 0.40 mL.

Does the PK2 pack include two 19/17 glass stoppers or must they be ordered separately?

Each flask ships with its own 19/17 glass stopper, so the PK2 contains two stoppers and nothing else needs to be purchased for basic use.
