Gilson VERITY Syringe Pumps

The Gilson VERITY Syringe Pumps are designed to deliver precise and reliable liquid transfers across a range of workflows, including HPLC, SPE, and general laboratory applications. Suitable for both small- and large-volume repetitive dispensing, these pumps integrate with VERITY liquid handling systems to support accurate sample transfers, dilutions, reagent additions, and mixing steps.

VERITY syringe pumps are available in single syringe, dual syringe, and dual syringe with tee configurations. They are designed for integration with VERITY GX-series liquid handlers and the 233 Sample Changer, enabling expanded automation within existing laboratory workflows.

  • VERITY 4020 Single Syringe Pump – Configured with a user-selectable small- or large-capacity syringe and a valve for directing liquid from a reservoir or probe. Designed for straightforward, single-channel liquid transfer applications.
  • VERITY 4120 Dual Syringe Pump with Tee – Features two user-selectable syringes (left syringe capacity greater than or equal to the right), one valve for directing liquid from a reservoir or probe on the left channel, and a tee connection on the right for combined or split flow paths.
  • VERITY 4220 Dual Syringe Pump – Supports up to two independently selectable syringes, which may be the same or different capacities. Two valves enable liquid direction from reservoirs or up to two probes. When paired in duplicate with a GX-series liquid handler, up to four independent fluid paths can be controlled, supporting higher-throughput, parallel sample processing.

Features

  • Multiple Configuration Options – Available in single, dual, and dual with tee formats to suit different applications
  • High-Precision Liquid Transfer – Supports accurate, repetitive dispensing across a broad range of application volumes
  • Flexible Syringe Options – Compatible with syringe capacities of 100 μL, 250 μL, 500 μL, 1 mL, 5 mL, 10 mL, and 25 mL
  • Wide System Compatibility – Designed for seamless integration with Gilson liquid handling platforms
