HOTPLATES

 


SEM Hotplates are suitable for all routine laboratory applications. They are rugged and durable and are available in a range of sizes and types designed for temperature uniformly over the whole top surface. The bodies are of mild steel, coated with white enamel or of stainless steel supported with rubber feet.

Cast iron top units are controlled with energy regulators, maximum 500°C. Aluminium top units are thermostatically controlled up to 300°C - Teflon "Silverstone" coated 280°C. Solid state instruments can be fitted for finer temperature control. Stainless steel surrounds can be supplied for sand bath heating.

A separate controller is supplied for the larger model 206 Cast iron top hotplate or for any other model when used in extremely corrosive environments. Special acid resistant element leads and 316 stainless steel is used on the heavy acid range of hotplates.

SEM heat controller can be used on any heating apparatus.

HC1 to 10 amps at 240V.
HC15 TO 15 amps at 240V.

*All hotplate specifications can be altered to meet customer requirements.

HEAVY ACID RANGE HOTPLATES

SEM Heavy Acid Range Hotplates are suitable for extremely corrosive environments. This range of hotplates covers a variety of sizes in cast iron and aluminium on request.

The hotplate bodies are constructed entirely from heavy gauge 316 stainless steel and element connections are fully sealed.

Single phase hotplates are supplied with a 10 amp or 15 amp heat control box of cast aluminium construction. This can be free standing on rubber supports or fixed to a wall via mounting lugs.

Three phase hotplates are supplied with a robust switching unit housed in a powder coated heavy gauge steel box and a single phase cord to power the energy regulator and three pole relay.

Teflon coated aluminium or austenitic iron hotplates are available in most sizes and digital PID control with removable temperature probe is an option on any hotplate.

*Specials made to customers requirements.
