Frequently Asked Questions
What is the difference between the GHS-550HS and GHS-550HSP models?
Both heat to 550°C with a 7×7 in glass-ceramic plate. The HSP adds PID closed-loop control and an RS232 port for tighter temperature accuracy and data output, while the HS provides standard digital heating and stirring.
Which models operate on 220–240V?
The UK/EU variants (GHS-550HSP-UK-EU, GHS-550HS-UK-EU, GHS-380HS-UK-EU) run on 200–240V 50/60Hz. The remaining SKUs are configured for 100–120V 50/60Hz.
What top plate material is used?
The 550°C units feature a chemical-resistant glass-ceramic plate, while the 380°C GHS-380HS uses a ceramic-coated top plate. Both resist common aqueous reagents and alcohols.
Are these sold individually?
Yes. Each SKU is sold as one unit (1/each) at the per-pack price listed above. Tiered pricing applies to multi-unit institutional orders.
