HandyStep® S

The HandyStep® S repetitive pipette combines the application advantages of the positive displacement principle with easy operation, robust design and an attractive price-to-performance ratio.
Thanks to the positive displacement principle, the HandyStep® S is often the easy solution for liquids that are difficult to pipette. This includes highly viscous or wetting media, high density media, foaming media such as detergents or highly volatile liquids.
Its balanced weight distribution and the practical ergonomic positioning of operating elements makes work more efficient, even when pipetting long series. The ergonomic finger rest relieves strain on the hand, the positioning of the dispensing lever is easy on the thumb, and the stroke can be set with one hand, even while wearing gloves. Tips can be ejected with the press of a button, without having to touch the tips, making tip ejection contamination free.
The HandyStep® S repetitive pipette works with the original BRAND PD-Tips //. Tips from many other manufacturers can also be used, providing maximum flexibility. The simple, robust design and purely mechanical, battery-free operation make the HandyStep® S a reliable lab partner.
