Are you packing up your Vernier equipment for storage over the summer? Here are some tips to ensure proper storage over a long break.

Go Direct Products
Do not leave them charging – better to leave them in a static state rather than charging. If you have a Go Direct® Charge Station (GDX-CRG), you can simply remove power to the station and leave the sensors in each bay.

Do not remove the battery – Go Direct products power down to tiny levels of current draw and should be fine over the summer.

Store in a cool, dry place – best not to leave them in a sunny window or other high-heat extreme for the summer.

Follow any specific probe instructions for storage – (such as pH, O2, etc)

LabQuest 3, LabQuest 2, LabQuest Stream, and Original LabQuest
If your school storage area is especially hot when the air conditioning is off for the summer, we recommend that you keep batteries in a location that remains cool. For details, see What is the best way to store LabQuest units over summer vacation?
LabQuest 2 (LABQ2) and LabQuest 3 (LABQ3)

  • Turn LabQuest completely off.
    (Hold power button until the shutdown countdown is shown and wait for the countdown to complete.)
  • Remove the battery.
  • Disconnect the charger.
LabQuest Stream (LQ-STREAM)

  • Turn completely off.
  • Remove the battery.
  • Disconnect the charger.
Original LabQuest

  • Turn LabQuest off (hold the power button down for 3 seconds).
  • Disconnect the charger.
pH Sensors and ORP Sensors
Store your pH Sensors, Oxidation-Reduction Potential (ORP) Sensors, and BNC electrodes vertically in the storage solution provided.

The storage solution should be refreshed periodically, and replacement solution can be purchased, if needed.

Colorimeter
Make sure no liquid (either in a cuvette or spilled) is inside your Colorimeter.
O2 Gas Sensors
Store your Oxygen Gas Sensors upright using the 250 mL Nalgene bottle that was shipped with the sensor.
Dissolved Oxygen Probes
Make sure your Dissolved Oxygen Probes are completely dry after emptying the filling solution and rinsing the sensor electrode and cap.
Optical DO Probes
The humid environment of the storage bottles in which Optical DO Probes are shipped is ideal for long-term storage. If the yellow sponge at the bottom of the storage bottle dries out, add a few drops of distilled water.
Ion-Selective Electrodes
Keep your Ion-Selective Electrodes in the humid environment of the storage bottles in which they were shipped. If the sponge at the bottom of the storage bottle has dried out, simply add a few drops of distilled water.
