Description
On each CELLSPIN stirring platform up to four spinner flasks
can be employed independently of their size. The CELLSPIN
spinner flasks are available in four different sizes – 100 ml,
250 ml, 500 ml and 1000 ml – to match individual needs of
cultivation scale. Using the conversion kit for impeller-type
flasks, the individual stirring positions of the stirring unit can
easily be adapted for use with other spinner flasks.
An optimised culture protocol is a key factor for successful
cultivation of cells. CELLSPIN allows you to precisely set parameters
such as stirring speed, pause intervals and pendular
angels for inversion of the rotation direction. The speed ranges
from 5 to 75 rpm and can be adjusted in steps of 2.5 rpm (5-40
rpm) or in steps of 5 rpm (40-75 rpm).
The CELLSPIN spinner flasks are designed to provide a
high surface to volume ratio ensuring improved oxygenation
over standard designs. The unique stirring mechanism of the
CELLSPIN spinner flasks relies on two glass pendula which
guarantee low shear forces while maintaining optimum mixing.
As most cells are very sensitive to overheating, the stirring
platform design prevents any release and transfer of heat to
the cell suspension. Owing to these specific measures aimed
at gentle cell cultivation, high yield expression from even the
most sensitive cell lines is possible.
