he Ultra-Furn Laboratory Muffle Furnace range is designed with the exacting requirements of the laboratory environment in mind.  State of the art control systems ensure consistent and reliable results.  Our tried and tested heating element and refractory designs offer prolonged service life, the LM range is attractively presented in a lightweight air-cooled cabinet finished in a durable epoxy powder coat which blends into any laboratory environment.

Maximum Temperature:                     1200ºC

Maximum Continues Temperature:    1150ºC

GENERAL DESCRIPTION

The chamber is manufactured from a 98% Alumina material and is supported by lightweight low thermal mass ceramic brick.  The bricks are machined to carry spiral elements of Kanthal A1 material. 

The chamber is equipped with a chimney for the removal of any undesirable gaseous contaminants.

For ashing applications, preheated air can be passed through the chamber and extracted through a large stainless steel chimney. (Optional extra)

The removable “hot box” is mounted in a lightweight steel cabinet designed to use convected air to provide a cool outer skin.  In the interests of the operator, the door moves on a parallel link system and an internal spring counter balance system ensures ease of movement. 

The entire cabinet is subjected to a seven-stage zinc phosphate anti-corrosion treatment and then a durable epoxy powder coat is applied.

INSTRUMENTATION

Standard instrumentation consists of a digital set, digital indicate, dual display P.I.D. temperature controller with power limiting facility and the capacity to auto tune P.I.D values to the characteristics of your process. This in turn signals a solid state, zero voltage-switching relay, causing minimal interference with other electronic equipment.

Platinum rhodium thermocouples.

A completely independent over temperature circuit protects the unit from over firing.  The unit is supplied in manual reset, which allows the unit to be operated unattended. 

A door switch isolates the elements in the interests of operator safety.

Various optional extras are available on request.

The E (economy) range of Muffle furnaces have been designed without compromising any of the essential features associated with reliability and prolonged service life.  The ruggedly constructed steel frame will endure the trials of a workshop environment, yet is equally suited to a laboratory bench top.

Maximum temperature:                      1200ºC

Maximum continuous temperature:    1150ºC

GENERAL DESCRIPTION

The chamber is manufactured from a 98% Alumina material and is supported by lightweight low thermal mass ceramic brick. The bricks are machined to carry spiral elements of Kanthal A1 material. The chamber is equipped with a chimney for the removal of any undesirable gaseous / volatile contaminants.

For ashing applications, preheated air can be passed through the chamber and extracted through a large stainless steel chimney. (Optional extra)

In the interests of operator safety the door moves on a parallel link system up and over, keeping the hot face away from the operator, the door handle doubling as the external counterweight.

The entire cabinet is subjected to a seven-stage zinc phosphate anti corrosion treatment and then a durable epoxy powder coat is applied.
