Quotation Request



In addition to fast or temperature controlled heating, a lot of applications also require liquids to be stirred. Using our laboratory stirrer SLR with heating, the process of mixing liquids can be selected from careful to intense, and the device can also be used for speedy heating up or controlled temperature adaptation.

*  Corrosion-resistant ceramic glass top plate
*  Excellent transmittance of the infrared light
*  The top plate can resist up to 700℃ thermal shocks
*  Hermetically sealed, corrosion-resistant, solid casing
* Fast heating and excellent temperature stability
*  External control by the connection of a Pt100 temperature sensor
*  Large LCD display for setting and monitoring of temperature and speed
*  A high-temperature indicator warns the user and prevents burning injuries
*  Compressed air connector optionally available for the use in aggressive environments
