New Capping System Simplifies Storage of Blood and Urine Samples

A novel system for re-capping sample tubes permits secure storage of blood and urine specimens for several days in case additional tests need to be performed.

Blood and urine samples are usually collected in vacuum tubes before being sent to a central laboratory for analysis. Following analytical testing, the vacuum tubes require storage for several days in case additional or follow-up tests need to be performed. To simplify the sample retention process Micronic Europe BV (Lelystad, The Netherlands) has introduced a unique postanalytical capping solution for blood or urine sample collection tubes.


The system comprises the Novitain Manual Capper CV750 instrument and Novitain Capcluster-50 multi-caps. The Novitain TPE Push Caps that make up the Capcluster-50 were designed to seal 13-mm diameter sample-collection tubes in a 50-tube format. The caps are manufactured from a chemically resistant medical grade hydrophobic polymer to ensure stored sample integrity.

The Novitain Manual Capper CV750 is an easy-to-use, stand-alone instrument. To seal sample tubes, a Novitain Capcluster-50 sheet is placed on the rack of sample tubes, and the rack is inserted into the Novitain Manual Capper CV750 rack entrance. A simple forward/reverse action of the black handle evenly caps all 50 tubes in less than two seconds. Following the capping step, the Novitain Capcluster-50 retaining foil can be easily removed to leave each individual tube securely capped. The tubes can be opened again using the tab attached to each cap without the need for additional tools.
