BRAND^® HandyStep^® touch is the first electronic repeating pipette with touchscreen operation and automatic tip ejection. Features a smartphone inspired user interface with a touchscreen for efficient access to functions in a simple swipe. Important information is always in view, and integrated help functions are just a tap away.  HandyStep® is lightweight, wellbalanced, and provides a convenient control layout for smooth dispensing and one-handed volume selection

In conjunction with BRAND® PD-Tip™ ll Precision Dispenser Tips, the HandyStep® offers nearly sixty different volume settings with accuracy, precision, and dependability. The open design allows use of third party tips—no more being locked into a sole source. The tip ejection system allows tip removal without handling.

Available with or without Inductive Charging Stand.

Features:

• Three pipetting modes: Pipette, Multi-Dispense, and Auto-Dispense
• Easy touchscreen operation with a color-coded display and important information easily accessed
• Simple tip ejection – fully electronic tip ejection reduces the risk of contamination
• Favorites function – save complex processes to avoid repetitive programming of frequently used procedures
• Automatically recognizes tip size of BRAND^® PD-Tip^® II and is also compatible with tips
  from other manufacturers
• Improved aspiration and dispensing speed control
• Optional induction charging stand – USB cable provided with pipette

HandyStep Touch S Includes these additional features:

• Sequential Dispensing Mode – Dispense up to 10 different volumes
• Multi-Aspirating Mode – Consecutive aspiration of the same or different volumes
• Titration Mode – Save the last titration result
• Switch between select modes with a filled tip – pipetting settings are saved
