Diamond® APEX™ Pipettors - Adjustable Volume

Globe Scientific Diamond® APEX™ adjustable-volume pipettors combine a lightweight, ergonomic design with a magnet-assisted piston for consistent plunger movement. These single-channel laboratory pipettors are available in nine volume ranges, from 0.1–2.5 µL to 1,000–10,000 µL, supporting individual sample transfers across a wide range of liquid-handling workflows.

A low-force plunger and shock-absorbing tip ejection mechanism help reduce fatigue during repetitive pipetting. Precise volume adjustment, an easy-to-read display, and a volume-locking mechanism help you set and maintain your selected transfer volume.

Why Choose Diamond APEX Adjustable-Volume Pipettors?

  • Support consistent pipetting: A magnet-assisted piston provides consistent movement through the first and second stops for aspiration, dispensing, and touch off.
  • Reduce pipetting effort: A low-force spring and seal design, ergonomic body, and silicone shock absorber in the tip ejector help improve handling comfort.
  • Maintain your selected volume: The locking mechanism helps prevent accidental volume changes.
  • Identify settings easily: A large display window shows the volume setpoint, while color-coded plungers help distinguish models.
  • Choose durable construction: A PVDF tip cone resists corrosion and shock, and a corrosion-resistant alloy tip ejector supports durability.
  • Simplify routine care: Fully autoclavable and UV resistant. Follow the product instructions for cleaning, autoclaving, and maintenance.
  • Select with confidence: Calibrated in an ISO 17025 accredited facility and supplied with a 3-year warranty.
