A quartz material / glass-encased, spiral-shaped, electrical heating coil with a large surface, which is mounted in a quartz material reflector shell with a handle, allows liquids to be heated indirectly by infrared radiation. This is used for the fast, economical evaporation or concentration of liquids. Due to this principle, only the surface of the liquid is heated very strongly, as the thermal radiation is absorbed even after shallow penetration, thus enabling gentle, uniform evaporation.In contrast to boiling evaporation, there is no loss of substance due to splashes from a moving boiling surface. Since surface evaporators are made exclusively from the material fused quartz / glass, it is possible to use the advantages of the material, such as good IR permeability, heat and heat change resistance, lowest electrical conductivity, exceptionally high chemical purity and resistance as a material. It complies with EC Directive 89/336 / EEC and EC Directive 73/23 / EEC.

Immersion heater for laboratory and electroplating technology Advantages: Maximum energy utilization through infrared radiation - the cladding tube is infrared permeable; through heat conduction - the cladding tube made of quartz glass enables particularly good heat transfer. Temperature resistance Since quartz glass has practically no thermal expansion, such immersion heaters are particularly resistant to heat changes. Acid resistance Quartz glass immersion heaters are almost resistant to acids except phosphoric acid above 300 ° C and hydrofluoric acid. They are therefore particularly suitable for the direct heating of chemicals in the laboratory and electroplating technology. electric security The cladding tube made of quartz glass is an excellent electrical insulator - safe contact protection; optimal electrical safety through earthing of the interior. In compliance with EC Directive 89/336 / EEC and EC Directive 73/23 / EEC.
