Size (O.D. x Length): 16 x 100mm. Round bottom culture tubes feature a phenolic cap which fabricated from special formula resistant to effects of temperature and steam in autoclaving. Deep-form 15-415 GPI threaded phenolic caps facilitate handling and sealing after autoclaving. Caps have a glued-in, white rubber liner.

CHEMetrics' leakproof reagent vials contain premeasured solutions of sulfuric acid and potassium dichromate. To perform the COD determination, the analyst simply removes the Teflon-lined screw cap from the vial, adds sample to the vial, and replaces the cap. The vial is then heated for two hours at 150°C in a standard digestor block.
