Oxygen solenoid valves with fine filter in TOC analyzers
TOC analyzers are used to determine the content of total organic carbon (TOC) in liquid and solid samples. Kendrion oxygen valves are responsible for the precise dosing of the oxygen required for the analysis in TOC instruments.
Advantages
- Grease-free for analytical applications
- Fine filter to eliminate chips and particles
- Extremely durable and failsafe
Oscillating solenoids for particle analysis
Analytical sieve shakers are used for separation, fractioning, and particle size determination. Our controllable electromagnetic drive makes sure that the sieve can be adapted to any bulk material. By producing a 3D throwing motion, the product to be sieved moves equally over the whole sieving surface. It effects that the size of the particles will separate the mesh. Sharp fractions are obtainable even after very short sieving times.
Advantages
- High performance with a compact design
- Ideally minimized eddy current losses
- Universal installation options
