The instrument now offers an unparalleled set of features and benefits to users of bulk reagent dispensers.The Preddator was originally designed as part of the scientists’ brief for a new reagent dispenser that could overcome 3 key issues:

  • Reduce tip blocking and improve assay data
  • Reduce the long-term costs of consumables
  • Reduce assay volumes, without compromising on accuracy and precision

  • Simple fluid pathway – Reduces dead volumes (~65ul) and tip blockages , Auto-clean function ,Reduces tip blockages, Dispensing from 10nl volumes, Miniaturises assays
  • Precise and consistent dispensing (0.7% CV at 500nl) – Improves assay data (independently verified)
  • Drop-on-drop capability – Repeatable dispensing positioning, to within 20um
  • Dynamic fluid range –Capably handles DMSO, proteins, crystallography, oils, matrigels, surfactants, cells and beads
  • Limitless patterns – Dispenses into 96-, 384-, 1536- and 3456-well microplates, evaporation wells, non-standard plates, microarrays and slides
  • Fast – Fills a 1536-well plate in under 10 seconds (on-the-fly)
  • Flexible – Suitable for a wide range of applications, handling up to 4 different reagents simultaneously
  • Small footprint – Ideal for today’s laboratories (footprint of just 750 square cm)
  • Low on-going running costs – Simple low volume fluid pathway, easy to maintain and clean
  • Open platform – Ideal for integration into a robotic platform

 

Preddator – The art of precision reagent dispensing.

From viscous reagent handling and cell dispensing to HTS.

The Preddator’s unique versatility and reliable performance makes it ideal for a wide variety of applications including:

  • Viscous reagent handling or HTS to Cell dispensing Assay development
  • Protein crystallography
  • Filling from a CSV file
  • PCR
  • Viscous reagent handling
  • Cell dispensing
  • Back filling
  • Dilutions
  • High throughput screening (HTS)
  • High content screening
  • Drop-on-drop dispensing
  • Stem cell research
  • MALDI spotting

Fast cleaning of the dispensing valves. For reliable nano volume fluid dispensing

 

Nano volume fluid dispenser

Features include:

  • Rapid cleaning of the Preddator’s high precision dispensing valves
  • Reduces the chance of clogging on the dispense the valves
  • The trough includes four holes for the dispensing valves to enter for cleaning
  • High performance air-blade drying technology
  • Sensors to alert the user when more rinse solution is required, or when the waste fluid capture bottle is full

The video above shows the precision in which the Preddator can perform low volume dispensing. The video shows the Preddator spotting out nine aliquots within each well of a 384 well plate and was done to highlight the incredible precision attainable by the system.

The Preddator is shown dispensing from one of four channels in step by step mode across a 384 well plate. an ideal option for cell dispensing and or multiple reagent dispencing
