Advantages of the tissue culture flask with the peel-off foil:
Available in all sizes: 25 - 300 cm2
Large pinched flap for a firm grip
Foil is peeled off before access to the cultivation chamber
Strong welding of peel-off foil
Multilayer foil material
Stacking ring offers stable and slip-free stapling of several flasks
Optionally available with barrier
This flask cannot be re-closed after the foil has been peeled-off.
The foil is welded securely to the polystyrene carrier.
It is important to use only filter screw caps. An internal pressure of more than 0.03 bar (0,00043 psi) in the flask without pressure equalization might raise the foil and result in leakage.
