When handling this biologically sensitive material, the plasma is taken from the donor and stored before being pumped to centrifuge to achieve the target fraction of cell material
A noteworthy application for Verderlab tube pumps is their use in
the preparation of bone marrow cells.
When handling this
biologically sensitive cell material, the plasma is taken from
the donor and stored in sterile plastic bags before being pumped
into a centrifuge to achieve the target fraction of cell
During this process the highly sensitive cellular
tissue must be kept sterile and transported in such a way that
the volume is not altered and the cell structure suffers no
mechanical damage from the pumping action.
Verderlab CD and SR
pumps were selected for this application specifically because of
their pulsation free pumping action.
Since the pump capacities
can be controlled and regulated electronically, the bone marrow
cells are not subject to damage when transferred to the
Thanks to their dual pump heads, Verderlab CD tube
pumps are also being used very successfully in other areas of the
pharmaceutical industry, for example in the preparation of plasma
The process of injecting the plasma protein into the
continuous working separators utilises a pulsation free mode of
action, thus creating sensitive, reproducible and registered
Verderlab CD pumps have a secondary rotor which
operates at an identical speed with fewer rollers, but which can
deliver a higher flow range - a small vacuum is created
The centrifugal process is enhanced significantly
through the suction of the centrifugal action.
processes are designed to operate with an RS 232 connection, in
