1.2 Product Overview
These products are made with an excellent heat-resistant,
anti-corrosive aluminum casting body with a high quality
powder coating.
The ceramic coated and stainless steel top plate provides
excellent chemical resistance, especially against strong acids
or bases.
Unlike traditional hotplate/magnetic stirrers, these units have a
high precision speed control system. (from 60 to 1500rpm)
with a continuously smooth revolution pattern.
The technically advanced PCB board eliminates an electrical
overload and regulates energy distribution. The bearing type
motor maintains gentle revolution over the lifetime of the
equipment.

damaged top plate can shatter during use.
7. Do not use metal foil, metal containers,
sand baths or other insulating material on
the hot plate – This can cause damage to
the top plate and shock hazard can exist.
8. Do not remove or modify the grounded
power plug. Use only properly grounded
outlets to avoid shock hazard. The
instrument is not rated for use in
hazardous atmospheres.
9. Use caution when heating volatile samples;
top surface and element can reach the
“Flash Point Temperature”
of many
chemicals. These hot plates are not
explosion proof. Fire or explosion may
result. Unit contains components which
may ignite such materials.
10. Use appropriate hand and eye protection
