How to Ship pH, Salinity, and Temp Probes

skibum9884 · 05/03/2012, 08:20 AM

I need to ship 3 GHL Profilux Probes (pH, Salinity, Temp), but no longer have the plastic tip protectors that they usually ship in that keep them moist. Does anyone have any idea where I could buy some? I've checked with GHL and Digital Aquatics already and they don't have any to sell

Thanks in advance,
David

The pH probe tip needs to be kept wet. Without the tip it came with, that may be hard to ship. Maybe wrap it in a baggie with some pH 7 buffer inside, and rubber band it closed just above the glass tip.

The other two are best dry and bubble wrap is fine for them.

FWIW, BRS recommended me to store a pH probe in pH 4.0 solution if it's put into storage. This is a while back, so my memory could be off!

pH buffer storage solution usually has a pH ~6.3

Mine does anyway.

Cool. Thanks! Should be ok because it won't be more than 2-3 days in transit.

Either the 4 or 7 is fine for storage.

Even diluted tank water is fine for pH probe storage. The idea is to be something a little salty so you do not draw salts out of the inside of the glass bulb, such as DI water can.
