Cell Culture Flask

Cell culture flasks are ideal vessels for long-term cell culture, large-scale cell expansion and contamination prevention in laboratories. They are manufactured from medical-grade polystyrene (PS) raw materials complying with USP Plastic Class VI standards. The non-treated surface is suitable for suspension cell culture. The TC-treated surface offers excellent hydrophilicity, ideal for adhesion and spreading of common cell lines.

◎ Angled neck design facilitates easy access for pipettes and cell scrapers.

◎ Frosted area near the neck allows convenient labeling, with clear volume graduations on both sides.

◎ Stackable design prevents slipping, saves incubator space and enables stable stacking.

◎ Multiple volume options available: 25mL, 50mL, 250mL, 600mL, 850mL. Supplied with both tight-seal caps

and filter vent caps.

◎ Vent cap (filter cap) equipped with a 0.22μm hydrophobic membrane, enabling efficient

gas exchange while blocking external microbial contamination.

◎ Product lot number is printed on each flask bottom and package for easy quality traceability.

◎ DNase/RNase-free, pyrogen-free, endotoxin-free, non-cytotoxic.

◎ Sterilized by EO or gamma irradiation, achieving a sterility assurance level of SAL=10-6.
