Stoppers

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.

Properties:

• Endotoxin-free
• Free of detectable DNase, RNase, human DNA
• All sterile lids are non-cytotoxic

With seal from TPE.

PP Cap (Pilferproof) 28 neck finish, with approx. 19.4mm inner mouth.

Made of ethylene propylene diene monomer rubber.

Autoclavable to 140 °C (steam).

Hexagon stoppers for NS connections.

Manufactured from borosilicate glass 3.3 which is resistant to heat and almost all chemicals. They meet the highest quality standards according to DIN 12252. Lower closed end of stopper features a "drip-tip" to ensure adhered liquid is returned to the flask. Hexagonal flat head prevents the stopper from rolling and allows stopper to be stood on end preventing contamination of the ground surface.

• Made from high quality polyethylene
• Ribbed plugs with 2 sealing ribs for very tight sealing
• Easy handling with a high, ribbed grip
• Easy to open by tilting ("one-hand operation")
