About this file

This document is an appendix listing chemical inventory for the Sabana Field Research Station's sample handling and processing room as of April 23, 2026. It details chemicals used in laboratory operations with their specifications, quantities, storage locations, and safety documentation references.

The inventory includes hydrochloric acid in multiple concentrations and forms (12.1N, 2N, 0.5M, 10%, and Trace Metal grade), totaling approximately 31,000 milliliters across glass bottles, plastic carboys, and Nalgene polypropylene containers. Additional chemicals documented are isopropanol (70% solution), potassium sulfate, ammonium fluoride, potassium chloride, and pH buffer solutions. All chemicals are stored in designated cabinets below fume hoods or in flammable cabinets, with container types specified and state of matter noted as liquid for all listed items. Safety Data Sheet (SDS) locations are provided via Fisher Scientific and Cole-Palmer supplier links for regulatory compliance and personnel safety reference.
