Flask heater LNG-500



LNG-500 flask heater is designed for heating liquids in 500 ml round bottom flasks at temperatures up to 300°C.

A device used in various laboratories to heat solutions in round bottom flasks of appropriate capacity. In addition, the device is also included in laboratory equipment used to heat liquids to boiling point and transition to gaseous state. The heating chamber of the device is made of heat-resistant mica, the strength of which is reinforced by refractory elements. The surface of the working chamber is protected by environmentally friendly glass cloth. Metal body of the flask heater is covered by anticorrosive powder paint. The heating element is chromium threads. The chamber corresponds to the form of a round-bottom flask, which is located in a casing insulated from the body of the device. This design ensures minimal heat loss, economical use of energy, and eliminates the risk of burns during laboratory tests. Temperature values are accurately maintained due to the built-in electronic temperature controller (power input). During experiments it is possible to smoothly change the temperature of liquids, keeping the set parameters for a certain period of time. Safety of the device is provided by digital regulator - the device disconnects from power supply when temperature limit value is exceeded and starts working again when temperature mode is restored. The equipment operates with alternating current with frequency of 50 Hz and nominal voltage of 200 V (deviation in voltage values - not more than 10%).

The LNG-250 flask heater is designed for heating liquids in 250 ml round bottom flasks at temperatures up to 300°C.

Features of design:

The heating chamber is made of heat-resistant mica with pressed refractory heating elements.

Working surface is protected by fiberglass cloth.

The heating chamber is shaped exactly like a round-bottom flask and is housed in a casing thermally insulated from the outer casing.

This design minimizes heat loss and is characterized by high energy efficiency.

Very precise temperature control through proportional-integral thermostat with feedback to the thermocouple control

Infinitely variable temperature control
