Micronic, Lelystad, the Netherlands, has launched the Novitain postanalytical capping system for the secure sealing of sample collection tubes after analytical tests have been conducted. The system includes the Capcluster-50, a 50-well storage rack, and the manual capper CV750. Novitain TPE push caps are suited for secure short-term sealing of 13 mm diameter sample collection tubes stored in a 50-well format. The Novitain Capcluster-50 retaining foil can be removed to leave each tube individually capped, in turn minimizing cross contamination. Each tube can be easily opened again using the tab attached to each cap without the need for additional tools. Compatible with automated preanalytical systems, the lightweight Novitain rack has an open well side design to ensure equal temperature for all sample collection tubes during cooled storage.
