GETTING STARTED
2.6 Using Osmocoll HNL Serum Control
26
Osmocoll
®
HNL (SS-039) is a processed, stabilized bovine serum
control, which is useful in a quality assurance program for the Vapro
osmometer. See Appendix B for more information.
For optimum results, always adhere to the following guidelines:
•
Upon arrival in your laboratory, refrigerate Osmocoll HNL.
Under refrigeration, the serum will remain stable until the
labeled expiration date.
•
Once opened, the product has a maximum stable life of 5 days,
if kept refrigerated and tightly capped, however the solution
must be at room temperature before running in the
osmometer.
Instructions
1
Run a sample of Osmocoll HNL control.
2
If the measured osmolality falls outside of the range listed on
the package labeling (each Osmocoll lot is assayed for osmo-
lality), you should suspect the calibration of the instrument.
Recalibrate the instrument using freshly opened Optimol
ampule standards. See Section 3.5 for instructions.
CAUTION!
Never calibrate the Vapro osmometer using Osmocoll HNL control solution.
