Aftermarket pH electrodes- any experience?
Darklight posted a topic in Pharmacology, Chemistry & Medicine
I have a lovely digital pH meter which has been a rock solid unit for 15 years. It's a corker But now the electrode is almost out of juice, and it isn't refillable ( I checked the manual ) 15 years is pretty good lifespan for an electrode ( I calibrate regularly ). But I priced an identical new electrode at $260 from the manufacturer pH meter has a BNC connector. There are a shit ton of aftermarket BNC connector pH electrodes on ebay for about $35 Anyone had any experience with using an aftermarket cheapie electrode attached to their lovely branded desktop pH meter? I'll do a side by side with the old electrode and a regular calibrate of course But if most people's experiences of cheap aftermarket pH electrodes is bad, I won't even bother waiting the 2 weeks for one to arrive from overseas -
Does anybody here make, or has anybody ever made any soap out of the fat of a cactus? I've heard of people making cactus shampoo, was wondering if anybody has ever defatted a cactus and made soap out of it. Just curious to know if it could be done or how the bars of soap would turn out. Cheers.
