The ergonomic and optimized design aloow relaxed long series pipetting quickly and with high precision. In conjunction with the positive displacement PD-tips the instrument gives you as many as 49 repetitive dispensings steps from a single aspiration.
It is ideal for routine or research applications in diagnostics, microbiology, molecular biology, biochemistry, immunology, environmental analysis and many more.
- for serial pipetting of volumes between 2 µl and 5 ml. A close-tolerance stepping mechanism allows the HandyStep® S repetitive pipette to offer precise repetition of the selected volume. With up to 49 dispensing steps from each aspiration, it is ideal for making aliquots of stock liquids.
- the instrument works on the positive displacement principle, making it suitable for routine dispensing, as well as for difficult liquids. Viscous, high density or high vapor pressure liquids can be dispensed while maintaining accuracy and precision.
- double-sided volume table on the back side for quick adjustments
- clear stroke indicator
- over-handed volume adjustment for right-handed and left-handed operators, even with gloves
- ergonomic finger loop to keep the hand relaxed
- separate tip ejector for contact-free ejection
- suitable for PD-Tips from BRAND® and compatible dispenser tips from other manufacturers
- DE-M-compliant according to German Measurement and Calibration Regulation
- with serial number and performance certificate
