FEP 250mL Baggie, 7.5mil

I have been a fan of these teflon "baggies" from Welch Fluorocarbon for a very long time. We used them extensively at Entropy for air source sampling and I would not think of using any other weighing container here at Resolution Analytics. They allow us to consistently measure low weights of particulate matter while keeping our background weight close to negligible. They have a very high heat and chemical resistance property allowing us to utilize them for an extensive variety of samples. In addition to having a great product line, Welch Fluorocarbon also imparts a personal touch to their customer service which I value a great deal. J. Bruce Nemet QA Officer Resolution Analytics, Inc.
