CELLTREAT Suspension Culture flasks are manufactured under the most stringent conditions and include a 100% integrity test to assure the reliability with your tissue and cell culture work. Class 100,000 clean room, USP class VI virgin polystyrene, and ISO 9001:2000 quality management systems all contribute to the consistent tissue and cell culture performance of our products. Suspension culture flasks are non-treated. Surfaces are flat and free from striation to provide improved transparency.

Flasks are available in four different sizes; 25ml (12.5cm²), 50ml (25cm²), 250ml (75cm²) and 600ml (182cm²). Flasks are provided with vent caps that contain a 0.22 µm filter to allow gas exchange and minimize the risk of cross contamination.

Innovative angled neck design offers excellent pipet access. Flasks include engraved graduations on two sides and ridges for easy stacking.

All flasks are packaged in easy opening sterile re-sealable (zip closure) bags with the lot number printed on each bag.
