Simple Accuracy Checks
Voluette and PourRite Ampule Standards are designed to work directly with Standard Additions accuracy checks in Hach procedures and photometer software. Use the TenSette Pipet to add precise spikes of standard and check percent recovery, to confirm analytical system performance.
Minimize waste
Open a fresh standard ampule for each accuracy check. Each ampule contains enough standard for one set of standard additions.
Reliable results
Sealed ampules prevent accidental contamination or evaporation of standard solutions.
