Each sample vial is uniquely marked with a sample number. The vials containing the dehydrated sample must be stored as directed. The dehydrated Vitroid™ sample is stable for a time exceeding the study schedule. |
| Packaging: | Set contains 10 sterile screw cap vials each containing a Vitroid™ (a small disk containing the possible organisms) and 10 - 99mL bottles of phosphate buffer. (Please note, buffer solution may not be provided with your sample. If this causes any concern, please contact PT Service ptservice@milliporesigma. |
| Preparation Note: | Description • This sample set contains 10 vials each containing a dehydrated tablet containing possible organisms. Ten sterile 100 mL phosphate buffered hydrolyzing solutions are also provided. (Please note, buffer solution may not be provided with your sample. If this causes any concern, please contact PT Service ptservice@milliporesigma. • The sample is the colored disk. If the disk is lodged in the cap, drop entire cap into the hydration fluid. • Ensure the disk has dissolved completely (no color remains) and aseptically remove the cap prior to analysis. The hydrolyzing fluid may be stored at room temperatures. • The bacteria are provided in dehydrated form for enhanced stability. They must be re-hydrated prior to performing the tests. The vials holding the bacteria are sterile in the sealed box. Once the box is opened it is recommended hydration and analysis is started immediately. • Each disk contains a high concentration of bacteria. Before you begin, make certain that appropriate methods and media are being used. Label each dilution bottle with the sample number, the study number prior to hydrolyzing the samples. All of these numbers can be found on the vial labels. Make sure to use a permanent marker that is water insoluble. • Do not transfer any disks into hydrolyzing liquid prior to warming it. If you are using an enzyme substrate test follow manufacturer′s instructions. If the result is questionable at the end of the incubation period, you may incubate for an additional 4 hours or as provided in the method. • It is important that you report values for Enterococci.
