Buchi K-350 and K-355 Distillation Units

E8-84 

   

The K-350 and K-355 are efficient and versatile laboratory distillation units which can be used for a variety of laboratory applications 
including Nitrogen, protein, alcohol, Sulphur dioxide, volatile acids and Phenol determination. The K-350 is an easy to use unit for 
classical Kjeldhal applications whilst the K-355 is more versatile and allows a variety of steam distillation options including methods 
which require a reduced steam output.
Key features include:

 



Compact standalone unit

 



Integrated timer

 



High performance steam generator

Buchi K-360 Advanced KjelFlex Distillation Unit

E8-84 

   

The advanced BUCHI KjelFlex K-360 is a modular and flexible Kjeldhal system. For classic nitrogen and protein determination such as Kjeldahl, 
TKN and Devarda in accordance with the official methods (§64 LFGB, AOAC, EPA, ISO, DIN). But can also be used for the determination of 
alcohol, sulphur dioxide, volatile acids, formaldehyde and phenols. The modular nature means that the KjelFlex K-360 can be expanded from a 
simple distillation unit to a semi-automated analysis system by combining with a titrator.
Key features and benefits of the K-360 system:

 



Automatic emptying of the sample tube after distillation

 



All internal and external components are easily accessed from the  
front - all glassware can be seen.

 



Automatic dosing of boric acid, sodium hydroxide and water

 



Acid-resistant pump for non-Kjeldahl applications available as an option
