StepMate Stepper

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.

TopPette 8-Channel Adjustable Manual Pipette

The TopPette 8‑Channel Adjustable Manual Pipette is a high‑performance multichannel pipette engineered for accuracy, reproducibility, and operator comfort in high‑throughput clinical diagnostics, molecular biology, and pharmaceutical research. Available in four volume ranges from 0.5 µL to 300 µL, this 8‑channel pipette allows simultaneous transfer of liquids across an entire row of a 96‑well microplate, reducing pipetting steps by up to 88% compared to single‑channel pipettes.
Every TopPette multichannel pipette is calibrated according to ISO 8655 and supplied with an individual calibration certificate, delivering exceptional accuracy (e.g., systematic error as low as ±2.4% at 10 µL) and precision (CV as low as ±1.6% at the same volume). The 9 mm channel spacing is perfectly compatible with standard 96‑well plates, deep‑well blocks, and tube strips. The lower housing on select models is autoclavable at 121 °C for 20 minutes, allowing routine decontamination for aseptic applications in cell culture and microbiology.
Key ergonomic features include a lightweight body, a low‑force plunger, a relaxed finger hook, and a staggered tip ejector that reduces ejection force by up to 50% compared to traditional designs, all designed to reduce user fatigue and the risk of repetitive strain injury (RSI). A large digital display provides unambiguous volume confirmation, and the volume locking mechanism prevents accidental setting changes during operation.
For the clinical laboratory scientist and molecular biologist, the TopPette 8‑channel pipette delivers the throughput, accuracy, and ergonomic comfort required for high‑volume ELISA, qPCR master mix distribution, clinical chemistry sample transfer, and drug discovery screening. For the patient, consistent, error‑free multichannel processing ensures that diagnostic results are reproducible and reliable, with faster turnaround times that directly support timely clinical decision making.
