APEX(+) Flat Screw Cap with O-Ring, compatible with green insert (1000 pieces)

These colourful caps feature a deep inner lip designed to fit snugly against the inner wall of the tube. This prevents the contents from coming into contact with the seal or threads, reducing the risk of sample contamination. Made from polypropylene, the same material as the tubes, both caps and tubes expand and contract at the same rate in response to temperature changes (e.g., during 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 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 placed for easy sample identification. The cap inserts are also available in various colours; you can choose between blue, green, purple, orange, red, white, or yellow. This means a wide variety 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.
