Caps for Storage Tubes

Push Caps or Screw Caps


NBS Scientific offers through its partner Micronic a wide range of caps for sample tubes, in different colors, sizes and with an external or internal thread. All caps are characterized by strong resistance to harmful chemicals, are made of special materials for long-term sample storage, or have O-rings for safe storage at ultra-low temperatures. All our screw caps are plastic caps for tubes.

We offer screw caps, but also push caps, in the materials EVA and TPE. The first (Ethyl Vinyl Acetate) is, due to its material, very suitable for long-term sample storage, and the second has the main feature that it can be pierced, without losing the integrity of the seal. Furthermore, manufacturers apply all kinds of innovations to their caps for sample tubes, including a space-saving format (low profile) that allows you to save up to 33% of freezer space.


All caps for sample tubes are compatible with the most common sampling/automation systems, and are known to preserve your sample for a very long time, without any deterioration. All plastic tube caps and push caps are manufactured in a clean room, and are free of DNase, RNase and pyrogens. You are therefore assured of a quality product.
