Sigma-Aldrich TPP tissue culture flasks. capacity 165 mL, Tissue Culture (TC)-treated surface, with cap (filtered), case of 36 ea. 36 ea

The inside surface treatment by TPP provides an optimal growth surface on the flask base for the most varied matrix-dependent tissue cultures. The untreated side and top inside surfaces reduce the amount of cell loss during the separation phases, because undesired tissue adhesion outside the growth zone is diminished.

The flask′s innovative shape is of such a design that devices inserted through the flask′s neck have optimal access to the entire base surface. This means that there are no "dead" corners that cannot be reached with pipettes or cell scrapers. This excellent accessibility is due to the large neck opening and the favorable angle of inclination. The angled neck also reduces the chance of accidental spills and permits "dribble-free" pouring.

The TPP filter cap has a welded membrane in the cap cavity to offer free gas exchange without gas flow alteration. For optimal flask breathing, all membranes are proportionally dimensioned to each cap size. The microporous hydrophobic membrane (cytotoxic free) itself is constructed of 2 layers of membrane material based on a white acrylic copolymer over nylon support. With an airflow rate of 4.5 (LPM /3.7 cm²/ 13.5 psi), the gas exchange properties of the filtered flasks are comparable to that of the standard cap flasks.

The TPP tissue culture flasks stand for high quality aspects.

For optimum tissue growth, the growth area is opto-mechanical treated. This enhances cell adhesion and cell growth.

The geometry of the neck guarantees total access of TPP pipettes, TPP scrappers and the TPP spatula.
