The PP-550DS offers 96 channel high performance pipetting that is ideal for low-volume or high-volume multichannel microplate pipetting and for serial dilution applications. Two models are available: The PP-550DS for working with higher volumes and the PP-550DS-L for low volumes. The microprocessor-controlled pipetting mechanism provides accurate and precise pipetting of microliter volumes of samples into 96 or 384-well microplates. The high-speed pipetting system provides short processing times by delivering liquids through up to 96 channels simultaneously with precise volume control.

The Personal Pipettor (PP) is a popular series of affordable liquid handling systems with the versatility and reliability required for today’s demanding laboratory environment. The PP series offers the majority of automated features that many laboratories need at a reasonable price, making it possible for each technician to truly have their own “personal” pipettor.

The PP-550DS is a truly affordable automated pipettor that utilizes the same technology found in all Apricot pipettors in a small-footprint single station version. The PP-550DS series use Apricot Designs’ unique head design which employs high-precision manufacturing to produce reasonably-priced heads that are independent of the pipetting mechanism. The operator can load and unload pipetting heads in a manner of seconds, allowing simple and easy set-up for the task at hand. The PP-550DS can be manually indexed if necessary for accessing 384-well plates.

Features

• Flexible design for for liquid transfers and pipetting operations for 96 and 384-well microplates and can also
  be used for serial dilutions by row or column (using manual indexing).
• 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.
• Economical and simple 1-position deck provides low capital investment and smallest footprint.
• Easily controlled through simple front-panel buttons; requires minimal operator training and no external computer is required.
• Small footprint conserves bench space and fits easily into suitably-sized hoods.

Options

• PP-550DS-L model: Low-volume version with 125 ul pipetting channels for optimal pipetting as low as 0.5 ul.
• PP-550DS model: High-volume version with 550 ul pipetting channels for up to 550 ul pipetting.
• Fixed tip heads with 8, 12 and 96 channels.
• Disposable tip heads with 8, 12 or 96 channels for Apricot 550 tips or Biomek® FX tips.
• Tip washing system with recirculating pump.
• Optional manual indexer for 384 microplates or serial dilutions.

Applications

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