Sampling Valve

Sampling Valves are very essential elements of process especially in the pharmaceutical production and biotechnological processes. GMTPTEC Valves for sampling are available in different sizes and models. We offer valves with welding flange, Tri-Clamp-, Ingold- or further other connections. A sampling position is easily to retrofit, since you can obtain all necessary components from us in a ready-to-use condition and directly attach them. 


Sampling Valve – Models

  1. Septal Sampling
    This simple type of Sampling Valve is built like a Tri-Clamp closure cap and is made of 316L stainless steel. Within the cap is a built-in silicone membrane, which works as a septum. Little holes in the metallic surface of the cap make it possible for a syringe needle to pierce through the silicone and take a sample out of the pipe or container.
  2. Membrane Valve
    These Sampling Valves contain in the standardized form two or three connections. If the valve needs to be steam-sterilized in a closed condition, they need three connections. The shape like a V is typical for those valves. The outgoing ports are ports for the supply and drainage of the superheated steam or alcohol of the sterilization process. These connections will later also be used for the actual sampling.


Sampling Valve – Fields of applications

Sampling is in beverage, pharmaceutical or also biotechnological productions in nearly every step necessary to examine the media. Alcohol level, cell growth, sterility testing, filtration testing and many other tests are reasons for various Sampling Valves within the production of fluids. At GMPTEC you always find a suitable solution for your process and if necessary, also a suitable Sampling Bag or Manifolds.
