VITREX Capillary tubes
micro-haematocrit tubes are quality products that
conform to international standard ISO 12772.
The tubes are supplied fire polished
at the colour-coded end, which we recommend should
be sealed with VITREX Sigillum Wax. Fire polishing
reduces wear on the centrifuge seals. Supplied with
colour-coding on the packaging and on the tubes in:
heparinisation (red colour)
heparinisation (green colour)
heparinisation (orange colour).
Each heparinised tube contains at
least 4 IU heparin as prescribed by the Standard.
The tubes are available in two types
of packaging: Dispenser vials of 100 tubes each for
hygienic and easy handling; and economy cardboard
boxes, which reduce transport and handling costs.
Special requirements regarding marking, dimensions
or impregnation can be met.
The Sigillum Wax plate has 2x24
numbered positions per pair, which makes it easy to
seal and transport samples. Each pair can be forced
apart and used separately. The even wax layer
ensures uniform sealing
