Proline Plus Single-Channel Variable Volume Mechanical Pipettors

Proline® Plus is Sartorius's durable mechanical pipette for everyday manual pipetting, with nine adjustable models from 0.3 µL to 10 mL.

How to Choose

• Pick by volume: choose the model whose range covers the volumes you pipette most. Accuracy is best in the upper part of the range.
• Match the tips by colour: the push-button colour tells you which Optifit tips to use: grey for 0.3–3 and 1–10 µL, yellow for 2–20, 5–50, 10–100 and 20–200 µL, blue for 100–1,000 µL, green for 500–5,000 µL and red for 1–10 mL.
• Always the same volume?: Proline Plus fixed-volume pipettes are preset, so there's nothing to set wrong.
• Filling plates or equipping a bench?: see the 8- and 12-channel models and the Proline Plus multipacks.

Sartorius now specifies the 3 µL and 10 µL models from 10% of their maximum volume (0.3 µL and 1 µL), in line with ISO 8655. Older listings may show 0.1–3 µL and 0.5–10 µL for the same pipettes.

Reading the Comparison Table

• Volume Range: the smallest and largest volume the pipette can be set to (1,000 µL = 1 mL)
• Increments: the smallest step you can change the volume by
• Accuracy: how close the average delivered volume is to the set volume, at the maximum volume; lower is better
• Precision: how closely repeated deliveries match each other, at the maximum volume; lower is better
• Colour-code tip-tray: the push-button colour, matching the tray colour of its Optifit tips

Accuracy and precision are Sartorius's ISO 8655 limits, measured with Optifit non-sterile tips.

Key Features

• Comfortable: light pipetting forces and an ergonomic finger support reduce strain during long pipetting series
• Thermal insulation: internal components are insulated so hand warmth doesn't affect results
• Easy care: fully autoclavable without taking it apart; only three parts to clean
• Easy calibration: re-adjust with the tool supplied, e.g. for viscous liquids
• Durable: high chemical and UV resistance, built for heavy everyday use
• Volume setting: click-stop adjustment and a large, easy-to-read display

In the Box

• Proline® Plus mechanical pipette and adjustment tool
• 12 Safe-Cone filters and tweezers (not with the 0.3–3 µL and 1–10 µL models)
• Quality control certificate and quick start guide

Tips, Filters and Documents

Each pipette's Safe-Cone filter and compatible Optifit tips are listed under Parts and Accessories; the filter size for each model is also on its product page. Safe-Cone filters keep liquid and aerosols out of the pipette: use them with non-filter tips, and replace them regularly and after any over-aspiration. The operating instructions are under Documentation.
