Silica Gel availability

Hello all,

Does anyone know where I can get Silica Gel on the High Street. I need to get some tomorrow (Wednesday) prior to setting off to Costa Rica early on Thursday morning. I thought I had plenty but it has gone missing.

Any help would be appreciated as I think the humidity in Costa Rica will be a danger to my E520 and lenses. According to their website, Jessops are out of stock in my local store.

Thanks

Hi Try your local double glazing merchant / glaziers as they put some in the alloy tube between the glass so they might sell you some

Well - possibly another camera store.

Try a chemists

Gun shops/Knife shops, outdoor gear specialists.

It seems to be used for dry flower collecting/artwork, so an art/craft shop.

Just possibly a marine chandlers

Maybe

Re: Silica Gel availability

Don't forget that silica gel absorbs water from the atmosphere, until it can no longer do so. This means that it often needs to be 'activated' before use to drive off the absorbed water. You can do this in a domestic oven on a low heat (IIRC 140 degrees C for an hour or so, but don't hold me to this - google it!). Once activated, keep in an airtight container.

It sometimes has a humidity indicator in it, usually cobalt chloride. When the gel is dry and safe it's blue; when saturated and unsafe, pink.

The silly little packets that are include with cameras and electrical equipment are pretty well useless - they're far too small and not sealed with the equipment.

When I was in the aerospace industry, gas turbine engines were often packed in a container with loads of bags of the stuff. For a helicopter engine about the size of a person, they used tens of kilograms - equivalent to several buckets full!
