Built-in memory maintains the last used speed and time settings during a power
interruption.
The stirrer increases speed at a steady rate until the set-point is reached, if
the spin bar is too large or the liquid is too viscous, the stirrer may not reach its
set-point or become de-coupled from the units drive magnet. The set-point speed
needs to be reduced. The unit is designed to ramp slowly to assure that the spin
bar stays coupled.
* The model 2000/200L unit contains a larger spin bar with a center
pivoting ring. Ring may need to be replaced after eight (8) hours of use.
Contact your VWR representative for replacement spin bars or rings.
