Manual Single Channel Positive Displacement Pipetters

Positive displacement pipettes support accurate liquid handling for laboratories working with viscous, volatile, foaming, dense, hot, cold, infectious, or non-aqueous liquids where air displacement pipettes may be less suitable. John Morris Group supplies Gilson MICROMAN E and DISTRIMAN liquid handling options for Laboratory, Life Science and Diagnostics, and Food and Feed facilities requiring reliable small-volume dispensing.

This category includes Gilson MICROMAN E manual positive displacement pipettes in 1 to 10 µL, 3 to 25 µL, 20 to 50 µL, 10 to 100 µL, 50 to 250 µL, and 100 to 1000 µL ranges, plus a Gilson DISTRIMAN repetitive pipette for repeat dispensing workflows.

Positive Displacement Pipettes for Difficult Liquid Handling

Positive displacement pipettes use capillary piston technology to place the piston in direct contact with the liquid, helping laboratories handle challenging samples with greater control. This makes them suitable for liquid handling tasks involving oils, glycerol, blood, solvents, foaming liquids, dense liquids, volatile samples, infectious materials, and other liquids where evaporation, viscosity, or contamination risk can affect pipetting performance.

  • Product Type: Manual single channel positive displacement pipettes and mechanical repetitive pipetting options.
  • Brand Options: Includes Gilson MICROMAN E and Gilson DISTRIMAN products.
  • Volume Range: Visible MICROMAN E options cover 1 to 10 µL, 3 to 25 µL, 20 to 50 µL, 10 to 100 µL, 50 to 250 µL, and 100 to 1000 µL.
  • Technology: Capillary piston positive displacement design helps reduce the effect of liquid properties on volume accuracy.
  • Applications: Suitable for molecular biology, clinical research, food testing, pharmaceutical QA, analytical chemistry, environmental laboratories, and difficult liquid handling workflows.

Choosing Manual Single Channel Positive Displacement Pipetters

When selecting a positive displacement pipette, match the volume range, sample type, tip system, contamination risk, dispensing frequency, and operator comfort to the workflow. Gilson MICROMAN E models are suited to accurate manual pipetting of difficult liquids, while Gilson DISTRIMAN is useful where repeat dispensing is required across multiple tubes, plates, or sample containers.

Facilities building a broader liquid handling workflow may also compare Manual single channel air displacement pipetters, Electronic single channel pipetters, and Filter tip pipette tips to match pipette type, sample risk, and consumable requirements.
