VVP Technology

Award-winning Volume Verified Pipetting (VVP) technology represents the very latest in air-based 8, 24 & 96 multi-channel pipetting.

Highly sensitive in-line flow sensors integrated into each and every channel translates to unique pipetting competencies.

Independent Volumes on All Channels

• Superior flexibility for 96 & 24-channel automated liquid handling.
• Expands pipetting workflow efficiency by several-fold over traditional tools.
• Perform plate normalizations, serial dilutions & other common routines in record time.

Direct Volumetric Measurement of Each & Every Transfer

• Ultimate pipetting confidence with real-time volume verification.
• Removes the guesswork from automated liquid handling once-and-for-all.
• Any liquid, at any volume…with zero liquid class development.

Live Pipetting Diagnostics & Error Recovery

• New levels of process security with continuous QC monitoring of all channels.
• More robust workflows with advanced user-defined recovery for ‘on-the-fly’ corrections.
• Final validation data report captures all pipetting data.

How VVP Works

VVP air-based pipetting tools perform all aspirate and dispense functions via precise control of vacuum and positive pressure, respectively.

A silicon chip-based MEMS micro-sensor assembly incorporated into each liquid channel measures the pressure differential across a known constriction. Volumetric flow rate is a linear function of this pressure differential, allowing for instantaneous calculation of the actual volume of liquid entering or leaving each tip.

By monitoring and adjusting to volumetric flow in real-time, all pipetting processes can be controlled and finely tuned for any liquid, automatically accommodating for temperature and viscosity differences.
