Probe: Air-saturated water •Reagent water at 20 C shaken/aerated to saturate •Maximum DO at 20 C ~ 9.00 mg/L •Meter result shouldn’t vary greatly from the saturation point •Correct for pressure and/or altitude differences
Product Description. Control Standard Endotoxin (CSE) is a widely used standard for endotoxin testing. It is a purified extract of E. coliO113:H10, the same strain used for the United States Pharmacopeia and the European Pharmacopeia reference standard endotoxin (RSE). CSE
Charles River has developed and optimized a range of quantitative and qualitative LAL reagent water formulations that provides increased sensitivity, greater linearity, and superior interference resistance. Our LAL testing instruments and reagents are licensed by the FDA for product release, and all of our accessory products are certified for the appropriate LAL testing requirements.
Pyrotell multi-test vials may be reconstituted with LAL Reagent Water (LRW), Pyrosol® buffer or Glucashield® buffer. Glucashield (1→3)-ß-D-glucan inhibiting buffer is used to render the assay endotoxin specific. Pyrotell lysate is
These cod test vials are comprised of automated technologies that offer precise analysis and details on the outcome of a test phase. These cod test vials are equipped with hydraulics for conducting compression tests and come with distinct power capacities.
