Xitech air samplers are designed to take un compromised air samples. The vacuum box design allows for the sample to go directly into a Tedlar bag without coming into contact with the pump. Tubing can be changed out for every sample so you don't have to worry about cross contamination. A Hi Vacuum box that pulls up to 22 inches of mercury is perfect for those tough sites. There is even a box for taking USEPA TO-17 Method samples.
