Internal Links: Combine with our General Laboratory Equipment, Heating Baths & Oil Circulators, and Electrochemical Instruments for complete turnkey laboratory setup.

Frequently Asked Questions (Hot Plate Sourcing Guide)

Q1: What is the difference between ceramic top hot plates and stainless steel hot plates?

Ceramic top plates offer exceptional resistance to strong acids and organic solvents, superior scratch resistance, and higher maximum temperatures (up to 550°C) with fast thermal response. Stainless steel plates provide robust mechanical impact resistance and uniform heat distribution for general non-corrosive heating up to 380°C.

Q2: Do Qiwei hot plates support external temperature sensors?

Yes! Our digital hot plates support connecting an external Pt1000 temperature probe that can be immersed directly into the liquid sample, enabling direct precision sample temperature feedback control ($\pm 0.5^\circ C$).

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.
