4

The SAIEISE WD30 Series Erlenmeyer Flasks are heavy-duty, screw-cap laboratory flasks designed for secure handling of liquids during mixing, storage, extraction, and sample preparation.

Manufactured from thickened borosilicate glass, these conical flasks offer excellent resistance to heat and chemicals while the integrated GL-thread polypropylene cap provides a tight seal for transport or short-term storage. The flasks are supplied without graduations, making them ideal for applications where clarity, durability, and containment matter more than volumetric accuracy.

Suitable for research laboratories, analytical work, sample handling, and general wet chemistry.
