D-vac mini tubes are available with color coded caps for easy identification according to CLSI coding recommendations. The d-vac mini tubes are made of plastic and contain additive in varying concentrations.
Additive choice depends on the analytical test method tested. The manufacturer of the test reagents and/or instrument on which the test is performed, provides these specifications. The mini tubes are also available as 13×75, which is easier centrifuge.
