Polystyrene tissue culture flasks with multi-use reclosable liquid-tight lid.

• Surface activated, uniform flat growth surface
• Crystal clear transparency
• Geometry of the neck reduces risk of media slop over
• Complete access to flask chamber from above
• Stable and slip-free stacking of multiple flasks

Flasks are available only with filter screw caps. If a vented screw cap is used, a build-up of more than 0,03 bar inside the flask could press open the lid.
