Hach Company Ozone Test Kit, Model OZ-2
This compact and low cost ozone test kit utilizes an easy to use color disc method. Simply grab a sample, add powder and compare sample color to the color wheel to arrive on an accurate measurement.
Hach Company Dissolved Oxygen Test Kit, Model OX-2P
Low dissolved oxygen levels in surface water systems usually indicate serious pollution. Adequate amounts are crucial for fish life, but conversely, DO must be excluded from boiler feed water to prevent corrosion. This test kit utilizes drop count titration and contains 100 tests.Method / Chemistry: Drop count t
Sigma Aldrich Fine Chemicals Biosciences Certified Vial Kit Low Ads
Supelcos new Low Adsorption (LA) vials are manufactured using a process that decreases the number of hydroxyl groups on the vials glass surface significantly reducing surface activity while improving analytical quantitation and minimizing pH shifts in the sample. This same process also removes unwanted surface metals such as sodium and boron that can contaminate samples and interfere with trace analysis. Unlike other methods used to decrease vial surface activity the elimination of surface activity in LA vials is integral to the manufacturing process and is not a chemical surface treatment.These vials and closures are designed engineered and manufactured for optimum performance in HPLC GC/MS and LC/MS applications. All of the parts of the vial system (vial cap and septum) can come into contact with the sample and are critical to the outcome of the analysis. We recommend using LA vials with MSQ polypropylene cap/PTfE silicone septa. This cap and septa combination was purposely d
