Osmometer Model 3300 User’s Guide
Sample handling
The sampling system kit supplied with your Model 3300 contains a spe-
cial sampler and a starter supply of disposable sample cells and cham-
ber cleaners. Each kit contains re-order information.
Be sure to replace the sampler plunger with each new test kit (500 sam-
ples). For instructions on this procedure, see
“ Sample plunger replace-
ment and verification
”
in Chapter 4.
The Model 3300 measures the osmolality of a sample inside the
sample cell while on the pipette. This feature requires sample
cells specially designed to match both the sampler and the
Model 3300. Do not use any other sample-handling system
with your Model 3300 osmometer, and do not use the Model
3300 sampling system with any other laboratory procedure.
Standards & controls
Advanced Instruments offers and recommends the use of specific stan-
dards and controls with your Model 3300 osmometer. Each type may be
used to assess a different aspect of your instrument’s performance. For
information on obtaining these standards and controls, contact
Advanced Instruments or an authorized representative.
Clinitrol 290 Reference Solution (Part No. 3MA029)
We recommend that you run samples of Clinitrol 290 Reference
Solution daily to check your instrument operation and confirm your cal-
ibration. You should also run the Clinitrol 290 Reference Solution when
you receive erratic results. Doing so will allow you to verify proper
operation or recognize and diagnose problems promptly.
Protinol (Part No. 3MA028)
Advanced Protinol protein-based controls, at 240, 280 and 320 mOsm
(±5 mOsm), provide control values that closely bracket those of most
serum samples. These controls are formulated to mimic the freezing
characteristics of actual serum samples, and they can be used to verify
