The new 'Promicrol'?

The new Promicrol is nothing *remotely* like the original stuff. The long and the short of it is that without HEAP sulphate, Promicrol is not possible. I've been in touch with scores of Chinese companies. They all say they can make it and will sell me a sample for $1000. They must think we are all s...

Re: KennyE 777 Panthermic Developers

Kenny, Do you have any further news regarding your panthermic/777 developer substitute? Although I haven't used Harveys 777, I used to develop with AB55, which I understand is almost the same. AB55, unfortunately, hasn't been made for many years. Kind regards, Ian Queensland Australia PS, I don't kn...

Re: Anyone tried the new 'Promicrol'?

Can anyone address my concerns re whether the HEAP I'm supposed to be receiving is real or not.

Re: Anyone tried the new 'Promicrol'?

I have placed the orders. (Thee separate Chinese companies). One of them just looks like a trading company. Naturally, I'm fully anticipating that they all send me bags of sand instead of the real chemical. I can make up some Promicrol or Atomal of I can get an accurate formula bi does anyone know h...

Re: Anyone tried the new 'Promicrol'?

I can [/i]try[/i] to change City Hall! If enough of us work at it, it'll happen. Bloody ridiculous about incandescent light bulbs. It's all this nonsense about global warming. The US isn't seeing much global warming at the moment. If I can buy 10kg of HEAP, I think I will. Australian Customs haven't...

Re: Anyone tried the new 'Promicrol'?

I was thinking more about both vacuum sealing and a freezer. If oxygen is the culprit, then both low temperatures and a restricted oxygen environment might offer very long term storage possibilities. I like glycin - for the very reason that it's so avid in its uptake of oxygen molecules but that ver...

Re: Anyone tried the new 'Promicrol'?

I've fiddled with ppd in years gone by. I got quite good at developing Kodak Tech Pan film. Some brews required as low as 4asa. However, the grain from a Minox negative 8x11mm could be enlarged to 16x20" with no more grain than a 35mm (D76) negative enlarged to the same size. I've written of loads o...

Re: Anyone tried the new 'Promicrol'?

By OPD, do you mean orthophenyline diamine? I used to make up brews with PPD. The grain was extremely fine but I would lose at least 50% of iso speed. Actually, I have played around with Microdol -X a lot. In high dilutions (around 1:10) and using long development times and restricted inversion, I c...

Re: Anyone tried the new 'Promicrol'?

One Chinese firm gave a "certificate of authenticity" but it was absurd. The certificate stated a combination of hydroquinone, potassium bromide, sodium sulfite and sodium carbonate ie just some rudimentary crappy development brew. Does anyone have any information on how HEAP was made? At least then...

Re: Anyone tried the new 'Promicrol'?

Bit too much hassle to faff around with liquid nitrogen. I am told though that glycin is stable when mixed with certain other substances. (But I don't know which). It is interesting that my packets of Promicrol are very old (ie over 25 yrs old) yet still work normally, as far as I can tell. Promicro...

Re: Anyone tried the new 'Promicrol'?

I did see something about freezing glycin. Also I understand thatusing an inert gas in the container has a beneficial effect.

Re: Anyone tried the new 'Promicrol'?

I'm told that glycin only has a shelf life of 6 months. Have you any information on that? Apparently it starts off as a light color and then goes brown (oxidizes) at which point it loses its efficacy. Ian

Re: Anyone tried the new 'Promicrol'?

I'm in Australia. I haven't checked the availability of glycin but if it's not easily available, I'll swap you some HEAP for some glycin. I have to pay for the HEAP on this coming week and then wait for it to arrive. I expect I'll have it in the next three or four weeks. Then I have to test it to ma...

Re: Anyone tried the new 'Promicrol'?

Some good news. I have found a manufacturer who is able to supply N-(beta-hydroxyethyl)-o-aminophenol sulfate. I've ordered a Kg of this and can supply anyone who might be interested in making their own original Promicrol. (The latest version of Promicrol, which doesn't have N-(beta-hydroxyethyl)-o-...
