List of materials for oxygen isotope extraction line for carbonates

Below is a complete list of equipment for constructing, using, and maintaining a ten-line vacuum extraction system. The addresses, telephone numbers, and some web sites of companies from which we purchased our equipment are at the bottom of the list. We provide this list solely to inform the reader of what we purchased and are using in our laboratory. We are not endorsing these companies, products, or guaranteeing prices. Also, we suggest you budget extra money (maybe $1,000 or more) to cover miscellaneous expenses that are not included above or to cover cost increases. (Some of the glass parts need to be joined together by a professional glassblower. The stainless steel tanks with ball joints were custom made and involved welding of stainless steel.)
