Tube Caps & Mats

The LVL screw caps incorporate a patented 2-phase TPE compression enabing an optimal leak-tightness. The double-phase sealing is a particularly innovative feature. While closing, the first contact between the lateral edge of the tube and screw cap guarantees the seal against liquids (liquid sealing), the contact of the screw connection with the upper end of the tube edge minimises the ingress and leakage of gases (vapour sealing).

Caps can be removed manually (see our single and multi-tube decapper/pickers) or using an automated decapper/picking system. Caps are offered in three different formats: pre-screwed on tube, in a cap rack (SBS 96/48) or loose in a bag. LVL offers more than 12 different cap colours, which can also be mixed column by column (pictured above) for larger quantities.

Externally Threaded Caps

• Lower profile for better space efficiency
• Double start thread iwth 180° maximum rotation
• Reduced risk of cross-contamination
• Best option for long-term sample storage

Internally Threaded Caps

• Patented TPE compression with permanently injected ring
• Cap cannot be overtightened 
• Taller profile of cap useful for manual handling

Push Cap 96 Mats

Designed for use exclusively with the LVL 2D racked tube system, push or septum caps are a cheaper alternative to screw caps. They are usually used if storage is limited to a few years, the storage temperature does not fall below -80°C and the samples only have to be stored and not shipped. Through the - also automated - pressing of the caps and the subsequent removal of the foil, the 96 tubes are closed individually at the same time. Also available as single row and column stripes.
