Tacta Multi-Channel Variable Volume Mechanical Pipettors

Tacta® multichannel pipettes bring Sartorius's premium mechanical design to microplate work, filling a whole column or row of wells in one stroke.

How to Choose

• 8 or 12 channels: on a standard 96-well plate, an 8-channel pipette fills one column (8 wells) and a 12-channel pipette fills one row (12 wells).
• Pick by volume: both versions come in 0.5–10 µL, 10–100 µL and 30–300 µL. Choose the range that covers your working volume; accuracy is best in its upper part.
• Match the tips by colour: grey for 0.5–10 µL, yellow for 10–100 µL and orange for 30–300 µL, matching the Optifit tip tray colour.
• Need single-channel too?: see the Tacta single-channel pipettes, or the Tacta 3+1-Pack, which pairs three single-channel pipettes with a 30–300 µL 8-channel.

Reading the Comparison Table

• No. of Channels: 8 or 12 tips filled at once
• Volume range: the smallest and largest volume the pipette can be set to, in µL (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 volume you set, at the pipette's 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 colour of the pipette's push button, which matches 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: the handle and finger hook let the pipette rest lightly in your hand, and low plunger forces reduce the risk of strain injury
• Optilock: locks the volume so it can't be changed by accident
• Optiload: spring-loaded tip cone seats tips with little force and seals them reliably
• Optiject: soft, controlled tip ejection
• Four-digit display: large and easy to read when setting a volume
• Easy care: fully autoclavable without taking it apart (121 °C, 20 min)
• Calibration adjustment: re-adjust for viscous liquids or other non-standard conditions

In the Box

• Tacta® multichannel pipette
• 12 Safe-Cone filters (not included with the 0.5–10 µL models)
• 4 identification tags, adjustment tool, quality control certificate and quick start guide

Tips, Filters and Documents

Compatible Optifit tips are listed under Parts and Accessories, and the Tacta datasheet and operating instructions are under Documentation. Safe-Cone filters keep liquid and aerosols out of the pipette: use them with non-filter tips (never with filter tips) and replace them daily or after any over-aspiration.
