1. Bag is the ultimate sampling bag solution based on Keofitt s renowned high guality and ultra hygienic sampling valve design The Keofitt Aseptic Sampling Bag protects the sample against airborne contamination while extracting the sample during transportation and storage The standard operating procedure involves steaming the sampling valve with the Keofitt Aseptic Sampling Bag connected in order to sterilize the sampling valve and the connection between the sampling valve and the Keofitt Aseptic Sampling Bag The 3 way valve is designed to seal off sample and ensure sterility even after valve closure The valve sealing part is never in contact with non sterile area 3 The valve is closed and the sample is 1 Valve is steam sterilized 2 Sample is taken sealed and sterile y i ip ip During sampling the sealing area is never in contact with non sterile areas The Keofitt Aseptic Sampling Bag with tri clamp connector is a universal sampling bag system that can be used with all small and medium sized Keofitt sampling valves as well as all other sampling valves that have a tri clamp connector outlet O MPORTANT Mini Tri Clamp and O ring for connection are not included Please purchase Item 900074 and 900075 separately The Keofitt Aseptic Sampling Bag is used in2. a wide range of industries such as breweries dairies and the pharmaceutical and biotechnological industries CM e During sterilization with steam the system will become hot and emits steam care should be taken when handling the system Use protection goggles and gloves KEOFITT USER MANUAL PAGE 7 ASEPTIC SAMPLING BAG FUNCTION The Keofitt Aseptic Sampling Bag is designed for extracting one single product sample The design as a single use Aseptic Sampling Bag greatly reduces the risk of sample contamination occurring due to insufficient sterilization of the sample container The Keofitt Aseptic Sampling Bag is available in 3 different sizes 500 ml 1000 ml and 2000 ml It is important to choose the adequate Aseptic Sampling Bag size in order not to overfill the bag O aura e An overfilled or over pressurized Aseptic Sampling Bag may result in material burst Pay attention to sampling process at all times STERILIZATION Sterilization is carried out by supplying steam through the sampling valve Steam flushes through the hose piece and through the 3 way valve The Keofitt Aseptic Sampling Bag is based on the Keofitt steam sterilizable sampling valve design According to a test carried out by DB Lab in Denmark steam sterilizing the connection to the Aseptic Sampling Bag becomes effective after just 1 minute s supply of steam at a pressure of 2 bar a 1 bar g 121 C ODimporranm e Sterilization takes place with 3 way va
