Our new range of flasks, available with filtered or vented caps, is the result of intensive cooperation between user experts and top development specialists.

Great importance has been attached to the tissue culture properties of the flask, the accessibility of the flask's interior, and the cap closure.


The New 300cm² Flask Offers The Largest TC Growth Surface Available!

TC Properties

The most important requirement of a tissue culture flask is an even surface refinement in the growth zone. This 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.

Accessibility

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.

Vented Caps

When the vented screw cap is tightened to the end position, the closed flask is liquid and gas tight. By simply unscrewing the cap one quarter of a turn, the flask is in the "VENT" position, with the inside of the flask being aerated through a defined gap opening. This guarantee that the gas exchange with the environment and the possible risk of contamination are kept to a minimum. In addition, the special flat thread profile of the caps stops excess tightening and thus allows the caps to be re-used multiple times.
vented cap vented cap vented cap The "Vent" marking on the screw cap indicates defined aeration. The clicked-in venting position is clearly seen by means of a slightly raised rectangle found on the highest point on the cap. When the cap is turned through 90° the flask closes and is gas-tight.

Filtered Caps

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 / 3.7cm² / 13.5psi), the gas exchange properties of the filtered flasks are comparable to that of the standard cap flasks.

Beneficial Features of the TPP Vented & Filtered Cap Flasks

  • Unique body shape with a wider neck allows easy cell retrieval and absolutely NO dead corners.
  • White-printed graduations are easy to read and include marking area.
  • Impeccable optical clarity for microscope observation.
  • Safe, stable stacking of flasks.
  • Flasks are made from high-grade, low-toxin polystyrene.
  • Screw caps are made from polyethylene.
  • Flasks are packaged in easy "peel-off" wrapping and each bag has a protective barrier to prevent scratching.
  • Package contents are guaranteed sterile by gamma irradiation.
  • Flasks are individually leak tested and each batch is quality controlled for sterility and cell growth.

TPP Vented Cap

If the screw cap is tightened to its mechanical end position, the flask is closed and both liquid & gas tight. By unscrewing the cap one quarter of a turn, it is in the " VENT " position. An audible click lets you know when you have reached it.

TPP Filtered Cap

The TPP yellow filter cap has its membranes welded to a rigid inside cap cavity, which offers free gas exchange without gas flow restriction and assures perfect membrane integrity when submitted to cap screwing tension.
