Analytical Specialties Inc. has been in the distribution business of supplying analytical laboratory supplies as the successor company to The Anspec Company, Inc. Saran Gas Sampling bags have been made for over 30 years as a cost effective alternative to the other sampling bag films. We added several other films to provide a complete sampling bag choice for our customers. In addition to manufacturing standard size bags we specialize in making custom designed bags for your specific needs. All of our sampling bags are made individually & tested to ensure leak free sampling bags. Analytical Specialties offers more fitting choices than other sampling bag suppliers. We offer specially developed patented on-off septum fitting manufactured in Kynar and Polypropylene, our stainless steel on-off zero headspace fitting and our flush mount 800 series fitting. In addition we offer any fitting readily purchased in the marketplace, such as, Halkey Roberts on-off, Jaco Union & Teflon septum fittings.
