USE AND FUNCTION 

BM  15  and  BM  30  Water  Baths  are  designed  to  be  used  in  bacterial  culturing,  cell  culture, 
coagulation  tests,  coliform  determination,  enzyme  reactions  and  other  general  and  special 
applications. 

The BM Series provide temperatures between 5°C above the ambient temperature and 99.9 °C 
and keeps the temperature stable within the given tolerances. 

BM  Series  have  circulation  function.  The  circulation  pump  and  etched  foil  heaters  which  are 
placed at the outer sides of the tank provide absolutely homogenous temperature distribution 
in the tank. They offer excellent temperature control of liquid producing a uniform and stable 
heating environment for the applications. 

The baths has a microprocessor control system. The heating is based on PID controlled system. 
There are two digital displays for heating function. One of them is temperature display the other 
is timer which can be programmed up to 99.9 hours and including HOLD position. 

All  components  which  are  in  contact  with the  liquid  are  made  of high  grade  stainless  steel  to 
resist corrosion. The tank is insulated with glass wool for operating homogenous temperature 
distribution. 

The BM Series Water Baths are manufactured according to the following standards:  
EN 61010-1, EN 61000-6-3, EN 50419. 
 
This device is in compliance with WEEE Regulation. 
 
If mentioned warnings in this manual are not considered, NÜVE will not be responsible from 
their results.
