QualiTru TruDraw aseptic milk sampling system

TruDraw is a single-use aseptic sampling system for liquid dairy products developed by QualiTru. It includes a disposable blue cap, a sterile 59 mL container and an attached sterile needle to draw a sample in, protecting against the risk of external contamination.

Aseptic sampling is of utmost importance in the dairy industry, where the income that farmers receive is directly linked to their products’ purity. Yet sampling is typically conducted by collecting raw milk from the top of a milk tanker with dippers, which is prone to contamination from the environment or dirty dippers.

TruDraw can be used for secure sample tracking of an individual container, which works with TruStream fittings and ports. Used in conjunction with QualiTru’s TruStream sanitary sampling ports, it can be drawn from the side or rear of a trailer, without having to climb on top of a tanker.

The system’s Single Samplers collect samples from QualiTru’s 12- and 7-channel sampling septa and provide a chain of custody process from sample collection to laboratory testing. Users simply twist the blue cap into alignment with the vial’s tab and hinge, then press down on the blue cap until it pierces through the vial’s lid.

After removing the needle’s safety cover, TruDraw is inserted into the sampling septum and product is drawn into the container. Once filled, the certified sampling person removes and discards the blue cap, with the sample aseptically sealed until the tamper-evident label is broken at the testing facility.
