Octet SPR Borosilicate Glass Vials. Manufactured using heat and chemical resistant borosilicate glass Octet SPR vials help you reduce your need for single-use plastics whilst small dead volumes help minimize the need to prepare excess sample. 0.9 mL vials are suitable for assays involving multiple replicates of single samples and 2.0 mL vials suitable for assays involving a larger number of replicates. Can be used in conjunction with Octet SF3 Sample & Reagent Racks where sample evaporation is minimized via a reusable septa.
