Product Description
For cell culture, SARSTEDT offers flasks with a growth area of 25cm2, 75 cm2 and 175 cm2.
All cell culture flasks are made of high-grade crystal-clear polystyrene which is processed into
a flat growth surface that is ideal for microscopic observation. All cell culture flasks are tested
and certified according to the “TC Tested” quality seal.
The flask geometry has the following distinguishing characteristics:
- All corners accessible with serological pipettes and cell scrapers.
- Large labelling fields on both sides on the neck, together with printed white scaling on one side a
nd engraved scaling on the other, to facilitate work.
- High stability of the flasks, reducing the risk of contamination. In addition, the stacking edge that has been applied
to the flask allows flasks to be stored securely on top of one another.
- The optimised sloping neck of the flask and the anti-drip edge allow the medium
to be tilted easily whilst at the same time reducing the risk of contamination due to spillage.
- The lot no and expiry date are printed on each flask and permit easy traceability after removal from the packaging.
- All SARSTEDT cell culture flasks are available with three different growth surfaces and can be clearly identified from the coloured lids:
Red = adherent cells,
Yellow = difficult, adherent cells,
Green = suspension cells.
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 ribbed quick-release cap is available in two designs:
-The filter cap has a membrane with a pore size of 0.2 µm, ensuring consistent, sterile gas exchange.
At the same time, the hydrophobic properties of the filter minimise the risk of contamination.
-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.
The cell culture flasks are packed in a bag with a re-sealable mini-grip,
which is closed with a temper-evident seal until it is opened for the first time.
