Appendix 2 - Seawater vacuum line (vessel mark-up).pdf

This document appears to be an appendix related to a federal solicitation for a custom-designed borosilicate vacuum extraction line. The key details are:

The National Institute of Standards and Technology (NIST) Chemical Sciences Division is seeking to procure a custom-designed borosilicate vacuum extraction line to enable researchers to acidify seawater samples, extract and purify the carbon dioxide, and collect the purified gas samples. The vacuum line will be modeled after a system used at the Scripps Institution of Oceanography. The contractor shall provide scientific glass blowing services to fabricate the vacuum extraction line, which consists of four modular units on the front side and a mirrored rear vacuum line. The line must include an acidification module, gas purification traps, and a sample collection module with pressure gauges and diffusion pumps. Preliminary schematics of the required components are provided in the appendices. The solicitation number is 1333ND24QNB130376, and the opportunity is being issued by the Department of Commerce National Institute of Standards and Technology.
