Feature:1. Mainly used for liquid heating in university laboratories, petrochemical, pharmaceutical, environmental protection and other industries.2. The laboratory thermostatic heating mantle is the most ideal heating equipment for laboratories and fine chemical devices.3. It uses hightemperature alkalifree glass fiber as an insulating material, seals the resistance wire in the insulating layer, and then weaves it into a hemispherical internal heater.4. It has the advantages of large heating area, fast heating, good heat preservation effect, no open flame, and not easy to touch glass machine.5. Rugged and durable, it adopts advanced nonelectronic electronic voltage regulating circuit, which has the advantages of long service life and large temperature range.Specification:Item Type: Heating MantleMaterial: Cold rolled steel, Alkali-free glass fiberUses: Electric heating jackets are mainly used for liquid heating in university laboratories, petrochemical, pharmaceutical, environmental protection and other industriesCapacity Specification: 250mLHeating Power: 180WTemperature Adjustment Range: Environment temperature ~ 350 (stepless temperature adjustment)Maximum Temperature: 380Working Time: Continuous.Package List:1 x Heating Mantle1 x Manual
