Volatile Solvent Pipette

The StepMate Stepper is a slim, lightweight manual repeating pipette that transforms tedious multi-dispensing tasks into fast, accurate, single-handed operations. Engineered on the positive displacement principle, this instrument excels where air-displacement pipettes fail — handling high viscosity fluids such as glycerol and Tween, high density solutions, and volatile solvents with exceptional precision and accuracy. Available in a single-channel configuration covering a volume range from 10 μL to 5 mL, this pipette provides the versatility required for high-throughput and routine laboratory workflows across clinical diagnostics, molecular biology, and pharmaceutical quality control.

Every StepMate Stepper is factory calibrated according to ISO 8655 standards, delivering outstanding systematic error as low as ±0.2% and random error (CV) as low as ≤0.2% at higher volumes. The instrument accepts seven sizes of disposable polypropylene dispenser syringes from 0.5 mL to 50 mL, offering up to 48 dispensing steps from a single fill. The entire unit is fully autoclavable at 121°C for 20 minutes without disassembly, ensuring sterility for aseptic applications in cell culture and microbiology.

Key ergonomic features include a lightweight body weighing only 0.5 kg, a smooth filling slide bar, an ambidextrous grip for right-handed or left-handed use, and a volume locking system to prevent accidental setting changes. A durable tip stop lever secures syringes firmly in place, and the five-position dial allows quick selection of step volumes without calculation.

For the clinical laboratory scientist and molecular biologist, the StepMate Stepper delivers the accuracy, reproducibility, and ergonomic comfort required for high-throughput ELISA, PCR master mix distribution, and clinical chemistry reagent preparation. For the patient, consistent, error-free repeat dispensing ensures that diagnostic results are reproducible and reliable, directly supporting timely and effective clinical decision making.
