CELLTREAT Tissue 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. The tissue culture surface treatment used for CELLTREAT products provides a negatively charged hydrophilic surface and results in a consistent cell attachment surface. Growth surfaces are flat and free from striation to maximize usable growth area and transparency.

Flasks are available in four different sizes; 12.5cm², 25cm², 75cm² and 182cm². Two different cap styles are available. Plug seal caps can provide a closed system or allow gas exchange with a one quarter turn of the cap. Vent caps contain a 0.22 µm filter to allow gas exchange and minimize the risk of cross contamination.

Innovative angled neck design offers excellent pipet and cell scraper 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.

CELLTREAT Scientific Products include a comprehensive "Quality Certificate" with every case of product. The CELLTREAT "Quality Certificate" includes the Part Number, Lot Number, Sterility Assurance Level and Dosage, Endotoxin/Pyrogen Free Assurance, Non-Cytotoxicity Assurance and RNase/DNase Free Assurance.
