Frequently Asked Questions
Are refurbished pipettes accurate?
Yes. Every certified refurbished pipette is gravimetrically calibrated to ISO 8655 against NIST-traceable weights and ships with a traceable calibration certificate. It performs identically to a new instrument.
What warranty do refurbished pipettes carry?
A 90-day warranty against defects in materials and workmanship on every certified refurbished instrument, plus 30-day returns on unused items.
How much do you save versus buying new?
Typically 40–60% off the price of a new equivalent, while meeting the same ISO 8655 accuracy specification.
Does each pipette come with a calibration certificate?
Yes — every refurbished pipette ships with its own calibration certificate showing measured accuracy and precision across its volume range against a traceable balance.
What are sterility-extended (EXP) pipette tips?
New, factory-sealed tips that are past their printed sterility date, sold with a manufacturer extension letter at a deep discount. They are ideal for teaching labs and general dispensing; for GMP, clinical or cell-culture work we recommend in-date sterile tips.
How do I know which pipette tips fit my pipette?
Use our tip compatibility finder, which matches every mount system (universal, Rainin LTS, epT.I.P.S., Sartorius Optifit, Thermo FinnTip and more) to in-stock tips by volume.
Do you accept purchase orders and provide a W-9 or COI?
Yes. We are procurement-ready and accept purchase orders (PO) and provide a W-9 and certificate of insurance (COI) on request.
How fast do orders ship?
In-stock items dispatch within 1–2 business days via UPS, with free shipping on orders over $500. You can also use your own carrier account.
Which pipette brands do you carry?
Rainin, Eppendorf, Gilson, Sartorius, Thermo Fisher, Oxford and more — across pipettes, tips and consumables.
