MAGNETIC STIRRER / HOT PLATE THERMOSTAT CONTROL

Magnetic Stirrer & Hot Plate combination with 'Thermostat' temperature control. Plain, rectangular, high temperature alloy top plate 200x180mm.

Front panel provides the user with mains switch, Thermostat heat control from 50 to 320deg.C. and speed control for stirring.

NOTE: For general boiling of water etc. to overcome heat losses, it is necessary for the plate to achieve maximum temperature of about 450degC, therefore the 'Simmerstat' control model is recommended for this purpose.

MAGNETIC STIRRER / HOT PLATE SIMMERSTAT CONTROL

Magnetic Stirrer & Hot Plate combination with 'Simmerstat' temperature control. 

Front panel provides the user with mains switch, heat control and speed control for stirring. Plain, rectangular, high temperature alloy top plate 200x180mm.

MAGNETIC STIRRER / HOT PLATE SIMMERSTAT W/PTFE

Magnetic Stirrer & Hot Plate combination with 'Simmerstat' temperature control. 

Front panel provides the user with mains switch, heat control and speed control for stirring. Rectangular, high temperature alloy top plate 200x180mm with PTFE (Teflon) coating to resist corrosion and for easy cleaning.

MAGNETIC STIRRER VARIABLE SPEED EPOXY COATED TOP PLATE

Magnetic Stirrer, with electronic speed control from approx.150 to 1500 RPM. Strong magnet stirs effectively up to the viscosity of glycerine.

Rectangular plate, 200x180mm, is epoxy coated to resist corrosion. Front panel provides user with the mains on/off switch and speed control.

MAGNETIC STIRRER VAR.SPEED PTFE COATED TOP PLATE

Magnetic Stirrer, with electronic speed control from approx.150 to 1500 RPM. Strong magnet stirs effectively up to the viscosity of glycerine.

Rectangular alloy plate, 200x180mm, is PTFE (Teflon) coated to resist corrosion and for easy cleaning. Front panel provides user with the mains on/off switch and speed control.

This model is now IECs standard "Large" model Van De Graaff. The 250mm diameter ball is a good size and is in proportion with all the rest of the instrument's construction.

This model now uses an insulation tube to protect the belt, and the pulleys, the belt and the combs are accessible for inspection, cleaning or adjustment at both the top and bottom ends of the tube. The belt is a long lasting Silicone rubber and both performance and reliability is excellent.

The whole instrument can easily be dismantled down to the components to reduce size for transport.  The drive unit can be removed easily for return should repair be required.

NOTE:  IEC no longer makes the smaller model with the 200mm diameter ball.

WATER BATH FOR USE WITH IEC HOT PLATE (BATH ONLY)

A useful Water Bath that is powered by an IEC Hot Plate. Two test tube stands can fit so biological work is low cost and convenient. The ends of the bath slide down to rest on the work bench for a stable support but also slide up to provide the smallest size for storage. The bath can be used also as a dry oven.

A Thermostat Control (CH4240-101) fits to the edge of the bath to control the Hot Plate so the water temperature is held constant. This control is purchased separately.    

For an approximate temperature control,  the careful adjustment of the heat regulator of the Hot Plate can keep the water bath reasonably steady but not as regulated and accurate as the Thermostat unit.
