Used Dispensers/Pipettes/Micropipettes in Rhode Island, USA

12

Overview

Dispensers, pipettes and micropipettes are precision liquid-handling tools used across biotech and life-science labs for accurate volume transfer from microliters to milliliters. They include single- and multi-channel air-displacement pipettes, positive-displacement models and repeat dispensers. Key selection factors are volume range, accuracy/precision, tip compatibility, ergonomics and calibration traceability. They’re essential for PCR, cell culture, assay setup and QC where repeatable, contamination-free transfers matter.

FAQ

What should I check when buying a used micropipette?

Verify calibration records, inspect piston and seals for wear, test accuracy across the volume range, confirm tip brand compatibility, and check for visible damage or sticky action. Prefer units with recent calibration certificates.

How should micropipettes be shipped to avoid damage or contamination?

Ship clean and decontaminated, remove tips and secure plungers, pack in foam or molded supports to prevent shocks, include calibration certificates and spare o-rings, and note any temperature-sensitive components for controlled transport.

What maintenance and calibration schedule is recommended?

Perform routine checks weekly (seal integrity, smooth plunger action) and user-level cleaning monthly. Professional calibration every 3–12 months depending on use and criticality. Replace worn tips, o-rings and lubricate per manufacturer guidelines.
