CellTreat Flasks are "Dead-Zone Free".
The Dead-Zone (or the angled section design on competitve flasks) is not treated for cell attachment and growth. Dead-Zones, inturn, waste both expensive serum and antibodies. Our "Dead-Zone Free" CellTreat Flasks maximize on the scrap and retreival of cells, while reducing overall expenses.
CELLTREAT™ Cultureware is integrity tested to assure the highest quality, reliability and performance. A "Quality Certificate is provided with every product and specific to each lot number combining both compliance and assurance information to guarantee sterility (gamma irradiated) and freedom of pyrogens and non-cytotoxicity, RNase, DNase, and DNA. Products are produced from USP class VI virgin polystyrene to assure flat and striation-free surfaces to maximize growth and transparency. All CELLTREAT products are manufactured in Class 100,000 clean rooms and certified to be ISO 9001:2000. Surfaces of CELLTREAT cultureware are available with tissue culture surface treatment and without treatment. Tissue culture treatment creates a negatively charged hydrophilic surface that is ideal for consistent cell attachment. Untreated surfaces, used for suspension and hybridoma cultures, are hydrophobic and do not facilitate cell attachment.
