Frequently Asked Questions (Sterilizer Sourcing Guide)

Q1: What safety mechanisms are built into Qiwei pressure steam sterilizers?

All Qiwei sterilizers feature multiple safety layers, including an automatic over-pressure relief valve, over-temperature thermal cutout, dry-burn prevention sensor, and a mechanical door safety interlock that prevents opening while the chamber remains under pressure.

Q2: Can Qiwei autoclaves sterilize liquid media as well as solid instruments?

Yes! Our automatic vertical and benchtop sterilizers feature dedicated liquid and solid sterilization programs with controlled slow exhaust settings to prevent media boiling over during depressurization.

Q3: Do you support OEM custom branding and wholesale distributor pricing?

Yes, as a factory-direct manufacturer, we offer complete OEM/ODM custom branding, customized UI panels, private label packaging, and tiered volume discounts for global laboratory equipment suppliers.
