Fixed Volume Pipette

The TopPette Single‑Channel Fixed Volume Pipette is a high‑performance manual mechanical pipette engineered for accuracy, reproducibility, and operator comfort in clinical diagnostics, molecular biology, and pharmaceutical research where the same volume is repeatedly transferred. Available in a wide range of fixed volumes from 1 µL to 10 mL, this pipette eliminates the risk of accidental volume adjustment, making it ideal for high‑throughput repetitive tasks, blood bank procedures, and quality control workflows.

Every TopPette fixed volume pipette is calibrated according to ISO 8655 and supplied with an individual calibration certificate, delivering exceptional accuracy (e.g., systematic error as low as ±0.5% at mid‑range volumes) and precision (CV as low as ±0.2% at higher volumes). The fixed volume design has fewer moving parts than adjustable pipettes, resulting in greater long‑term reliability and calibration stability. The lower assembly on select models is fully autoclavable at 121 °C for 20 minutes, ensuring sterility 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 permanently visible volume marking for immediate identification. The universal tip cone works with most standard pipette tips, and the smooth plunger action allows fast, fatigue‑free operation.

For the clinical laboratory scientist and medical technologist performing repetitive pipetting tasks such as adding the same reagent to hundreds of samples, preparing standard curves, or aliquoting patient specimens, the TopPette fixed volume pipette delivers the accuracy, consistency, and simplicity required for reliable diagnostic results. For the patient, the elimination of volume adjustment errors ensures that every sample receives the exact same treatment, supporting reproducible, reliable diagnostics with fewer repeat tests and faster turnaround times.
