Screw cap, for tissue culture flask, 2-position, without filter

Product Description

The quick-release cap is particularly user-friendly because only a 1/3 turn is needed to close or open it.

When several cell culture flasks are being processed in parallel, the caps are often simply placed on the neck of the flask.

To prevent accidental self-closing of the easily turned quick-release caps, a ‘stop’ has been built into the thread.

When closing, this ‘stop’ can be felt as slight resistance.

The two-position screw cap (without filter) enables gas-tight sealing of the flasks in the closed position,

whilst, in the ventilation position, the cells can be cultivated with consistent gas exchange (arrows point up and down).

A recognisable click confirms that the cap has been secured in the ventilation position and will not fall off.

A gap in the ribbing, together with arrows on the cap, allow for a simple haptic and visual check of the closure position

when working and when in the incubator. There is no need for laborious manual checking of stacked flasks in the incubator

to ensure the caps are in the right position.
