This manual pipette pump is a handheld liquid transfer device designed for use with glass and plastic serological pipettes in laboratory environments. The pump supports aspiration and dispensing of liquid volumes ranging from 0.1mL to 100mL, with calibrated performance aligned to ISO 8655 standards. Constructed from chemical-resistant materials, it supports routine use in biochemistry, microbiology, clinical testing, and pharmaceutical quality control workflows. The design eliminates mouth pipetting practices, reducing operator exposure risk for commercial laboratories and industrial testing facilities.
The pump delivers volume accuracy of ±0.5% and repeatability of ≤0.2% CV across its operational volume range, measured according to ISO 8655-2 calibration protocols using distilled water at 20°C. These specifications apply when used with compatible graduated pipettes of corresponding volume class.
The main body weighs approximately 65g and incorporates a non-slip silicone grip surface. One-handed operation controls aspiration, dispensing, and blowout functions via separate lever mechanisms. A three-position speed adjustment knob modifies suction rate to match liquid viscosity, reducing splashing and bubble formation during pipetting.
Housing and internal structural components are fabricated from ABS polymer with PTFE piston seals and silicone gaskets. These materials resist contact with common laboratory reagents including dilute acids, bases, and organic solvents. The pump mechanism has completed 100,000 actuation cycles in fatigue testing under standard laboratory conditions.

The universal connector accepts three interchangeable rubber gaskets, enabling secure attachment to all standard glass and plastic pipettes with volumes of 0.1mL, 1mL, 5mL, 10mL, 25mL, 50mL, and 100mL. No additional adapters are required for switching between pipette sizes within a workflow.
The pump supports precise liquid transfer during DNA/RNA extraction, PCR master mix preparation, and protein purification procedures. Accurate reagent dispensing maintains reaction consistency for sequencing and protein analysis workflows in research and commercial testing laboratories.
Sterilizable detachable components and leak-resistant sealing support aseptic liquid handling for media preparation, cell seeding, and bacterial inoculation. The design prevents cross-contamination between culture batches in pharmaceutical and industrial microbiology facilities.
Clinical laboratories use the pump for sample pretreatment in biochemistry assays, immunoassays, and hematology testing. Consistent volume transfer supports reliable test data for diagnostic screening and patient sample processing.
Drug formulation laboratories and quality control departments utilize the pump for raw material sampling, standard solution preparation, and in vitro activity testing. The ISO 8655-aligned performance supports documentation requirements for regulated pharmaceutical operations.
Environmental monitoring and food testing laboratories apply the pump during sample preparation for water quality analysis, food additive measurement, and pesticide residue detection. Accurate pretreatment volumes support quantitative analysis of target analytes in industrial compliance testing.
Insert a compatible pipette into the universal connector and secure firmly. Select the appropriate speed gear for the liquid viscosity. Depress the suction lever gradually to draw liquid to the target volume, taking care to avoid introducing air bubbles into the pipette column.
Position the pipette tip against the inner wall of the receiving vessel. Press the dispense lever steadily to release liquid. For complete delivery, activate the blowout button to expel residual volume from the pipette tip. Remove the pipette after dispensing and wipe the connector surface before storage.
Detachable components may be autoclaved at 121°C and 0.1MPa following disassembly. The main pump body should not undergo full autoclave sterilization. Clean external surfaces with laboratory disinfectant between uses. Recalibration is recommended at six-month intervals for high-usage environments.
