 Polystyrene Lids

Greiner

Lids offer protection against contamination and evaporation during sample storage and cell cultivation. Four different polystyrene lids are available. High profile without condensation rings is mainly used for non TC-treated 96 well microplates. High profile with condensation rings is recommended for cell culture applications, since it ensures an optimum oxygen supply to cultivated cells due to improved gas exchange. Low profile lids contents are protected against evaporation and contamination, and the covered microplates can be easily gripped on the side in automated processes. Universal ultra low profile lids is compatible with a whole range of different microplates, provides the greatest possible protection against evaporation, and is also suitable for use in automated systems....

 Sealing cap assemblies Nalgene™, PP

Nalgene

 Tamper-evident screw caps, PP

DWK

Tamper-evident screw caps for Laboratory bottles with DIN thread. Temperature resistance: max. 140°C.
The integral plastic ring tears when the cap is first opened and is retained on the bottle neck. Therefore it can be clearly seen whether the bottle retains its original seal. After first untwisting, can be used as "normal" screw cap....

 Accessories to Cell Culture Flasks DURAN® TILT

DWK

The DURAN ® TILT Light Shield is a removable white silicone sleeve that covers 94% of the bottle surface. The sleeve blocks damaging ultraviolet light, protects the glass surface from damage, and facilitates safer handling.

The DURAN ® GL 56 Bottle Tags can be used for individual colour coding or for fixing the light shield to the bottle....

 Capping systems Matrix™ SepraSeal

Thermo

The Matrix™ SepraSeal sealing mats are suitable for securely sealing sample tubes with or without 2D code. For sample access, the caps can be removed with the practical cap removal tool (Cat.-No. 6.254 390, please order seperately) or pierced once. The pre-slit versions are suitable for multiple piercing. The self-sealing function of the pre-slitted elastomer maintains sample integrity....
