Proper Sensor Storage

We are often asked if any of our sensors require special storage. There are a few sensors that need to be stored properly in order to stay in good condition:

• Oxygen Gas Sensors should be stored upright. This is easily done by storing them in the bottle in which they were shipped.
• Dissolved Oxygen Probes should have the filling solution emptied and rinsed out, then stored dry.
• pH Sensors should be stored in the storage solution provided. Replacement solution can be made (10 g KCl in 100 mL pH 4 buffer solution) or purchased (order code PH-SS, 500 mL for $12).
• Ion Selective Electrodes should be stored in the humid environment of the storage bottles in which they are shipped. If the sponge at the bottom of the storage bottle dries out, simply add a few drops of distilled water.

This is just one of the many items that can be found in our new Vernier Technical Information Library (TIL) on the Vernier Support page.

Fifteen Years Ago in this Newsletter...
In the spring of 1987, we included a compatibility report about using our products on the new Apple® IIGS and Laser 128 computers. We also mentioned that we were going to convert some of our programs to the IBM PC.

Tombstone Science
Here lies Isaac Newton - A body at rest tends to stay at rest.
Here lies Euclid - or at least his elements.
Here lies Fermat - There isn?t enough room for a proper epitaph.
Here lies Heisenberg - maybe. If we indeed knew precisely where he was, we would not know where he is going.
