They've been in business a long time. I first ordered from them
about 1986 and have done business with them since.
I'm now putting another order for them togeather.

Amoung quit a few items of interest they carry a good selection
of bottles. Their line of Boston Rounds, clear or amber, wide or
narrow mouth, are supplied with polycone or polyseal caps.
Those caps and others can be ordered seperately. Those
caps are a combination cork within a screw cap and as
sure a seal as one could hope for.

Another good source is, www.microessentiallab.com . They
carry a huge variety of indicator papers including ph, fix silver,
and of course antifreeze. Dan

triethanolamine 85%

Greetings to the group. I have been using phenidone+ascorbic developers for over a year, and owe many thanks to Patrick Gainer and others who have shared their results.

The TEA sold by tri-esssciences.com is 85%, and I assume the remaining 15% is probably water? Does this have an impact on storage life of PC-TEA? 99% pure TEA is available from other sources.

That 15% IIRC, is MEA and DEA. Dan
