Product Overview
VWR Signature EHP Adjustable Pipettor 89079-976 (1000–5000 µL) – Unused
This VWR Signature Ergonomic High-Performance (EHP) single-channel, variable-volume pipettor, catalog number 89079-976, covers a 1000–5000 µL range for manual laboratory liquid handling.
Designed for repeated milliliter-scale transfers, the EHP series focuses on mechanical precision and ergonomic design to reduce fatigue during long bench sessions. It is a tool built for steady, repeatable work rather than electronic automation.
Product Condition
Unused, new old stock. The pipettor has never been placed into service. The manufacturer’s box shows signs of handling from storage, while the instrument itself remains unused and clean.
Product Overview
The VWR Signature EHP pipettor is a manual, air-displacement instrument intended for higher-volume laboratory workflows. Volume is adjusted using a continuously adjustable micrometer mechanism with a locking ring to prevent drift. An extended finger rest, reduced-force plunger, and adjustable stainless steel tip ejector support controlled operation during extended use. This model is validated using ISO 8655 gravimetric methods under defined conditions.

Frequently Asked Questions
What is the volume range of this pipettor?
This model is adjustable from 1000 to 5000 microliters.
Is this an electronic pipette?
No. The Signature EHP series uses a fully manual, mechanical air-displacement design.
What tips should be used?
It is intended for use with compatible universal tips appropriate for the 1000–5000 µL range.
Does this pipettor require calibration?
Periodic calibration and verification are recommended for all precision pipettors, typically following ISO 8655 procedures.
Are there other part numbers for this same model?
This unit is identified by VWR catalog number 89079-976 and European part number 613-5266.
Is this unit unused?
Yes. This pipettor is unused new old stock and has not been placed into service.
Built for consistent milliliter-scale work without unnecessary complexity, this VWR pipettor is ready to return to the bench where controlled, repeatable handling still defines good lab practice.
