APEX(+) Flat Screw Cap with O-Ring, compatible with purple inserts (1000 pcs.)

These colourful caps feature a deep internal lip that fits snugly against the inner wall of the tube. This prevents the contents from coming into contact with the seal or the threads, reducing the risk of sample contamination. As they are manufactured from polypropylene, the same material as the tubes, both the caps and tubes will expand and contract at the same rate in response to temperature changes (e.g. freezing or thawing), minimizing the possibility of leakage. Furthermore, they have been tested together for 95 kPa compliance, making them suitable for sample transport under UN3373 regulations when combined with appropriate secondary (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 fitted for easy sample identification. The cap inserts are also available in a variety of colours, you can choose between blue, green, purple, orange, red, white or yellow. This means a wide selection 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 from RNase, DNase, DNA and pyrogens.
