Micro-biological sampling valves for small volume samples
Widely used within the brewery, food, dairy and beverage industries, the Alfa Laval SB Micro Sample Port enables representative aseptic and microbiological samples to be taken in small volumes from tanks and pipework.
The Micro Sample Port is used to take aseptic and microbiological samples in small volumes from tanks and pipework.
The sampling is done by unscrewing the closing cap and inserting a 1 mm hypodermic needle through the rubber plug. Replacement of the rubber plug should only take place when the tank is empty and pressure has been released. It is done by unscrewing the press screw until it is released from the holder and the rubber plug is released. Then the press screw is remounted firmly.
Before sampling, the plug should be sterilized with alcohol. Since the inner part of the rubber plug sits flush with tankwall or pipework surface, this part is automatically cleaned during tank or pipework cleaning.
The Micro Sample Port is made in a simple, sanitary design and consists of a housing made as a socket for direct welding into tankwall or pipe-work, a rubber plug which is positioned by a press screw and a closing cap.
