KD Scientific introduced its UltraSpense 2000 that eliminates edge effects and delivers more viable cells uniformly to 384 well microplates when compared to conventional peristaltic dispensers. The net result is that the accuracy of seeding is much improved, leading to more reliable results. By simply recovering the perimeter row of a 384 well plate, a 25% gain in usable assays is achieved with CHO, Hek293 and Cos-7 cells.
UltraSpense 2000 solves many problems experienced with peristaltic dispensers with a specially designed coated manifold that uniformly distributes material to all 8 tips. This is combined with a proprietary pumping algorithm that overcomes the natural tendency for fluids to accumulate on the outside of the manifold tips.
