Cell Culture Flask

Primo ®Cell Culture Flasks are available with 3 different growth areas: 25, 75 and 182 cm 2
Flasks are manufactured with 100% USP VI crystal class virgin polystyrene and high quality polyethylene to ensure optimal surface for your cells.

The production occurs in 100,000 grade clean-room environment under an ISO 9001/2008 Quality System.

Flask surface is flat and seamless to maximize the available growth area; the surface of the dishes is vacuum-plasma treated to create a negatively charged and hydrophilic surface; this treatment ensures a more even and consistent cell attachment together with optimal cell growth.

Two different cap styles, plug or filtered, can be used in both open and closed systems:
Plug Sealing Caps: Standard polyethylene caps can be used in closed systems, providing a liquid and gas sheer seal. Simply unscrewing the cap one quarter of a turn, the flask can also be used in open system cultures.

Vent Caps: Vented polyethylene caps contain a 0.22µm hydrophobic filter to allow gas exchange and minimize risk of cross-contamination.

Innovative angled neck design offer good pipette and cell scraper access
Upper triangular and wider base shape provides stability and a protruding ridge on the back side of the flask allows easy stacking.

There is a special area near the neck for easy marking, moreover both flask sides have engraved graduation.

All the Flasks are strictly tested for leakage.

Primo ®Cell Culture Flasks are sterilized by gamma radiation and certified non-pyrogenic
Packaged in durable zip resealable self-standing plastic bags allowing flasks to remain upright and reduce contamination.
