15 mL PP Centrifuge Tubes

Features of TPP Tissue Culture Flask with re-closable Lid 115 / 150 cm2:

• Multi-use re-closable liquid-tight lid
• Complete access to flask chamber from above
• Safe, stable, slip-free stacking of multiple flasks
• Optionally available with barriers with additional safety zone

It is important that only filter screw caps are employed. An internal pressure of more than 0.03 bar (0,00043 psi) in the flask without pressure equalization might raise the lid and result in leakage.

Features of TPP Tissue Culture Flask with peel-off Foil 25 - 300 cm2:

• 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

• 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.
