APEX(+) Screw cap with O-ring, compatible with white insert (1000 pieces)
These colourful caps feature a deep inner lip that fits snugly against the inner wall of the tube. This prevents the contents from coming into contact with the seal or thread, reducing the risk of sample contamination. As they are made of polypropylene, the same material as the tubes, both the caps and tubes expand and contract at the same rate in response to temperature changes (e.g. during freezing or thawing), minimising the possibility of leaks. Furthermore, they have been tested together for 95kPa compliance, making them suitable for sample transport in accordance with UN3373 regulations when combined with suitable secondary packaging (e.g. Specisafe SH0100SS, SH0300SS and SH1300SS) and tertiary packaging (e.g. SH1000 or SH1200).
The top of the cap features a recess into which a colour-coded cap insert (CP3346 series) can be inserted for easy identification of samples. The cap inserts are also available in various colours; you can choose between blue, green, purple, orange, red, white or yellow. This means that a wide range of colour combinations can be generated to colour-code samples in the laboratory.
The caps are compatible with APEX plus and APEX White Label series tubes.
The caps are manufactured in a clean environment and are certified free of RNase, DNase, DNA and pyrogens.
