Inner surface is treated to create a negatively charged hydrophilic surface ideal for consistent cell attachment. Growth surfaces are flat and free from striation to maximize usable growth area and transparency.
Flasks have canted necks to offer excellent pipet and cell scraper access.
Plug seal caps provide a closed system or can allow gas exchange with a one-quarter turn. Vent caps allow gas exchange and minimize the risk of contamination using a 0.22 µm hydrophobic membrane filter.
Engraved graduations on two sides and ridges for easy stacking.
All flasks are sterile (gamma irradiated) and are packaged in easy-to-open, sterile bags that have a re-sealable zip closure. RNase-free, DNase-free, DNA-free and non-pyrogenic. Lot numbers are printed on all bags.
Manufactured in accordance with ISO 9001:2000 quality management systems in a class 100,000 cleanroom.
CELLTREAT™ products include a comprehensive quality certificate with every case of product. The certificate includes the part number, lot number, sterility assurance level and dosage, endotoxin/pyrogen-free assurance, non-cytotoxicity assurance and RNase/DNase-free assurance.
