Frequently Asked Questions (Water Bath Sourcing Guide)
Q1: What is the maximum operating temperature of Qiwei thermostatic water baths?
Our standard thermostatic water baths operate from ambient temperature up to 100°C with an accuracy of $\pm 0.1^\circ C$. For higher temperature requirements up to 300°C, we recommend our High-Temperature Oil Baths.
Q2: Do Qiwei water baths feature dry-run protection?
Yes! All digital water baths are equipped with automatic low-water level and dry-run cut-off protection, immediately shutting off heating elements to prevent damage if water evaporates below safe thresholds.
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.
