Globe Scientific Diamond® APEX™ fixed-volume pipettors combine a lightweight, ergonomic design with a magnet-assisted piston for consistent plunger movement. Available in 14 fixed volumes from 2.5 µL to 10,000 µL, these single-channel laboratory pipettors support workflows that repeatedly require the same transfer volume.

A low-force spring and seal design helps reduce pipetting effort, while a silicone shock absorber cushions the tip ejection mechanism. A PVDF tip cone and corrosion-resistant alloy tip ejector support durability during everyday laboratory use.

Why Choose Diamond APEX Fixed-Volume Pipettors?

• Simplify repeated transfers: Each model delivers one specified volume without requiring volume adjustment between transfers.
• Support consistent operation: A magnet-assisted piston provides consistent movement through the first and second stops for aspiration, dispensing, and touch off.
• Reduce handling fatigue: A lightweight, ergonomic body, low-force plunger, and shock-absorbing tip ejector help improve comfort during repetitive pipetting.
• Choose durable construction: The PVDF tip cone resists corrosion and shock, while the alloy tip ejector provides corrosion resistance.
• Identify models easily: Color-coded plungers help distinguish pipettor volumes.
• 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.
