96-Channel Liquid Handling Workstation - ToronLH™ 96 Series
ToronLH™ 96 Series Automated 96-Channel Pipetting Workstation
The ToronLH™ 96 Series 96-channel liquid handling workstation fills, transfers, mixes, and dilutes an entire 96-well plate in one pipetting stroke. Molecular biology, immunoassay, and cell culture labs use it in place of repetitive manual multichannel pipetting. Swappable 96-channel heads cover 1 µL to 1000 µL, and the system also pipettes 8 channels at a time. A moving plate table carries plates under the fixed head, so each transfer stays aligned. Operators build and run protocols from an Android tablet over a cable or Bluetooth.
Four models match different throughput and volume needs. The ToronLH™ 96A2 and 96A4 hold 2 or 4 plate positions and accept the 20 µL and 200 µL heads. The 96B2 and 96B4 add support for a 1000 µL head for larger transfers. The four-position models also unlock an advanced software mode for longer, multi-plate protocols. Custom 3-position or 6-position layouts are available on request.
The two-position models measure only 475 mm wide, small enough for a biosafety cabinet, clean bench, or fume hood. Bluetooth control lets operators run protocols with the cabinet sash closed. Pipetting heads swap by hand in a few steps with no tools or service visit. Each head stores its calibration data on a QR code, which the tablet scans when the head goes in. The instrument then identifies the head type automatically.

- Emergency Stop Button: halts motion at once for operator safety
Theory and Method
The ToronLH™ 96 Series uses air displacement pipetting, the same principle as a handheld air-cushion pipette. Each of the 96 channels has a piston inside a cylinder, with a tip pressed onto the end. When the piston rises, it lowers the air pressure in the tip and draws liquid in. When the piston falls, the air cushion pushes the liquid back out. Because the air gap separates the piston from the sample, liquid never touches the mechanism.
All 96 pistons move together on a single drive, so every well receives the same volume at the same moment. Precision depends on how finely the drive controls piston travel, which allows minimum steps of 0.1 µL on the 20 µL head. Liquids with different viscosity or surface tension behave differently in an air cushion. Adjustable aspirate and dispense speeds compensate for these differences. Reverse pipetting draws an extra volume and leaves it behind, which improves accuracy for viscous or foaming liquids.
The software combines these basic moves into higher-level functions. Mixing aspirates and dispenses repeatedly in the same well to blend sample and reagent evenly. Serial dilution moves a fixed volume across successive rows or plates to build a dilution series. Stepper pipetting draws once and dispenses several equal aliquots. Program linkage chains steps across plate positions into complete multi-step protocols.
