The TPS-24 offers 24 channel high performance pipetting that is ideal for serial dilution applications and for multichannel microplate pipetting. The microprocessor-controlled pipetting mechanism provides accurate and precise pipetting of microliter or sub-microliter volumes of samples into 96, 384, or 1536-well microplates. The high-speed pipetting system provides short processing times by delivering liquids through 8, 12, 16 or 24 channels simultaneously with precise volume control.

The Total Pipetting Solution (TPS) represents a new generation of affordable liquid handling systems with the versatility and reliability required for today’s demanding laboratory environment. With the innovative Externally Sealed Pipette (ESP) tips, the TPS pipetting system surpasses its competition in terms of applications diversity and reliability. This powerful pipettor has a compact size that easily fits on laboratory benches and also can be placed in suitable laboratory hoods.

The TPS-24 uses Apricot Designs’ unique head design which employs high-precision manufacturing to produce reasonably-priced heads that are independent of the pipetting mechanism. The TPS-24 electronically loads and unloads pipetting heads in a manner of seconds, allowing simple and easy set-up for the task at hand. The TPS-24 will automatically index the pipetting head if necessary for accessing 384-well or 1526-well plates. When disposable tip heads are used, the TPS-24 will automatically load the required number of tips for the programmed operation.

Features

• Flexible design for serial dilutions by row or column and can also be used for liquid transfers and pipetting operations for 96, 384, and 1536-well microplates.
• Uses the unique easy-change head system from Apricot Designs, allowing the user to build a diverse head library with a reasonable investment. The heads are interchangeable with other Apricot pipettors.
• The 6-position deck is user-configurable for portrait or landscape orientation to allow serial dilutions by row or column.
• Automatic disposable tip loading and unloading. The disposable tip loading location is accessible by robotics for expanded capacity.
• Intuitive graphical user interface via serial interface control.
• Small footprint conserves bench space and fits easily into suitably-sized hoods.

Options

• Fixed tip heads with 8, 12, 16 and 24 channels.
• Disposable tip heads with 16 or 24 channels for Apricot ESP tips or Biomek® FX tips for 12 channels (TPS-24 automatically loads the correct number of tips for portrait operations).
• Tip washing system with recirculating pump.

Applications

• Serial dilution (by row or column)
• Plate replication
• Plate reformatting
• Reagent addition
• Compound addition
  

Automation

The open deck design makes it easy to use robotics to supply labware and disposable tips to the TPS-24. It
can be integrated as part of an automation workcell by combining it with laboratory automation software
and robotics from Apricot’s sister company Biosero,
Inc.
