Anyone got a good source for these?
We currently get ours from webber scientific and they are incredibly fragile. So fragile, that the last two times new ones came via UPS, they arrived broken. A recent design change makes these hydrometers so tall that we have had to design an 18-inch tall "gravity bong" out of 2" clear pvc with a base because the hydrometers will not float in a 500 ml graduated cylinder.
And now after looking at the hydrometer the wrong way, it cracked. I understand that they are glass instruments and need to be handled with care, but this is ridiculous. We need a source of sturdier more compact hydrometers that will stand up to pulling gravities every day from twelve uni-tanks.
any help is greatly appreciated.
