So your lab techs are running a cell viability assay, they need to aliquot 4.7ml of media into eight wells in a row, and last thing they need is a pipette that seizes up halfway through or bleeds serum past the graduation marks like a cheap pen.

We've run these GPPS pipettes through gamma sterilization at 25kGy give or take, and the resulting COA shows zero DNase/RNase activity bioburden below detection right off the line — though if you're doing something like PCR workflow where any trace enzyme shutdown is catastrophic, we'll toss in an extra SGS lot test (adds roughly 3 days to lead time) but most buyers just trust the standard COA.

5L cases ship packed inside double-wall cardboard with foam nest inserts, we do individual blister-wrap for sterile singles and bulk packs of 50 for non-sterile runs, but the MOQ for OEM customiztion like color-coded tops or longer barrel is 10,000 units per size and that's pretty standard for any Chinese tooling change.
2-year replacement warranty but no, you can't swap out a single cracked pipette from a burned batch without us seeing photos of the lot number — that's just how all gamma products work and the real risk isn't breakage anyway it's teh filter plug staying dry inside a wet package which we actually check on every outbound pallet.

Payment is 30% deposit with the balance before shipment, T/T or L/C at sight, but if your PO is over $50k we can do Net 30 after the first order clears; shipping time form Shanghai to Los Angeles is usually 22 days or so assuming Customs doesn't hold the ISO certs (keep your 9001 and FDA docs ready when the broker asks).
MOQ depends on the size and customization level—typically around 10,000 pieces for standard sizes like 1ml or 10ml. We can adjust based on your specific needs, just reach out with your requirements.
Lead time is usually 15-25 working days after order confirmation and deposit, depending on quantity and customization. We'll give you a precise timeline once we know your specs.
Yes, we can provide CE, ISO 9001, SGS, RoHS, and FDA documents upon request, including batch-specific test reports. Just let us know which ones you need.
Yes, the graduations are permanent and printed on both sides with color-coding for each size, so they're clear and easy to read from any angle. The color varies by volume to help you grab the right pipette quickly.
Absolutely, we accept OEM customization for packaging—like adding your logo or using specific box sizes. The pipettes are individually wrapped by default, but we can tailor it to your needs, with MOQ applying.
