Glycin anyone?

[Kirk Keyes]

Corning makes the most popular stirring hotplates from the labs I've worked in, but the Thermolyne plates are good too. And they go for less that Cornings tend to go for.

Tom,
That's very helpfull, thanks again.

 

[hka]

And where does one get a magnetic stirrer? Sounds like it's well worth a purchase.

I bought a couple of week ago a stirring hotplate at ebay for less than 100 euris.

Glycine is a nonpolar amino acid. CAS # 56-40-6
Glycine is an inhibitory neurotransmitter in the CNS

Photographic Glycin CAS # 122-87-2 (p-hydroxyphenylglycin)

Neblette describes photographic Glycin as "a slow, powerful developer which keeps well in solution." Glycin works well in combination with Metol and Hydroquinone.

I have seen another notation for Glycin but with the same CAS #.

N-(4-Hydroxyphenyl)glycine
Molecular Formula: C8H9NO3
Formula Weight: 167.16
Registry number: 122-87-2

Could this be the same as mentioned above as the (p-hydroxyphenylglycin)?

 

[Ole]

It is the same. One uses "para-" to designate the same as the other one does with the "N-(4-" bit.

Well, this got lost!!! Sorry to be so tardy. What I have is in an Excel spreadsheet -- how do I attach or post this?

Thanks!

Ed

Sean has added Excel formats as an allowed attachment. I recall posting one after asking him about adding the format.

Ole,
Thanks.

DIY option for mine

Corning makes the most popular stirring hotplates from the labs I've worked in, but the Thermolyne plates are good too. And they go for less that Cornings tend to go for.

I have a magnetic stirrer that has room under the aluminum top plate for a heating element. So I added the heating element from a bunn commercial coffee 'keep warm' stand to it. It works like a charm when it comes to getting the last of the metol chunks dissolved, holding the solution at about 160F.

Over Christmas I intend to add some idle temperature controllers and a solid state relay to facilitate finer temperature control for some emulsion making experiments that I have planned for the future.

Now if someone has a lead on cheap used pipette stands , etc, I would be happy as a clam.

What to do to make a warmtone version of the ANSCO 130, Variant 1 recipe?
Any help is welcome.

 

[john_s]

However, I have determined that Glycin is soluble in Triethanolamine (TEA). I have prepared concentrated stock solutions of Ansco 130/TEA and will be testing it against the standard formulation over the next week.

Ansco 130, Variant 1

A Solution
Triethanolamine 130 ml
Metol 4.4 grams
Hydroquinone 22 grams
Glycin 22 grams
Triethanolamine to make 200 ml

B Solution
Water 700 ml
Sodium Sulfite 100 grams
Sodium Carbonate 160 grams
Potassium Bromide 11 grams
Water to 1 liter

I have some glycin that will take me some time to use up. I'm thinking of making up the whole lot because the powdered glycin doesn't keep well.

Is there anyone who has been using this TEA version who can recommend it?

 

[Richard Wasserman]

John,

I have no experience with the formula you have cited, however I keep my glycin in the freezer and it lasts for a long time that way.

Richard Wasserman

 

[john_s]

Thanks Richard. I have a fetish about mixing up stock solutions not very often. I'm going to try to mix up some 130 double strength which would probably last better than standard strength. I'll post my results.

 

[Murray Kelly]

John, I am also keeping the dry powder in the freezer and sofar it looks fine.
However, I had some very old (black) glycin which I tried to disolve in an acid solution and some did go. It was light tea coloured and only about half went into solution. The rest, slightly damp, I disolved easily in TEA and it was strong coffee coloured.
I haven't done anything much with either.
They have both kept the same colour for 6 months now. The only drawback I can see is that they might change the pH of a formula unless you make an allowance for it.

Wasn't this thread merged with the one on Ansco-130 and reformed as a sticky?

I remember posting the question there if anyone had experience with Voightlander 222 but there was no reply. I thought to try it on microfilm, since exposure with that for pictorial is essentially 'under-exposed'! It's 99.1 % water and I'm 'frugal' so it appeals in that way, too.

VOIGHTLANDER 222 (From Phot-O-Vergne Wiki)
Sodium Sulphite (anhydrous) 1 gm
Sodium Carbonate (anhydrous) 6 gm
Glycin 2 gm
Water to 1 litre

Times vary from 12-15 mins for over-exposed negative to 60-120 mins for under-exposed negatives.

Ansco 130 stock at normal concentration keeps well over a year. I've posted a few times on here about how my stock solution, mixed in April of 2007, was still working as of two weeks ago. (I haven't been to the darkroom since, but I assume it's still alive. ) DMax is excellent. The only key is to seal the bottles up tight. If the developer goes bad (I had one litre do that) it goes very dark brown/black and is obvious. I suspect that bottle has a leak.

 

[Murray Kelly]

OK Jim, a very honest answer. You don't know. Nor doeas anyone else!
Most developers keep best in airtight bottles, filled to the brim. I even squirt gas into the bottle, as an added protection. Lord knows what organic gasses do to developers? The plastic bottles suck in as the gas dissolves.
If this stuff (glycin) keeps as well as rodinal I will be happy.

Amazingly, I have kept FX-1 in glass sealed ampoules (not with the alkali) since 1959 and it still works fine. Nearly all gone now, but. Still, makes the point that keeping the air out will ensure the developer won't go 'off'.

Murray: I'd be grateful if you'd post the results of your experiment with Voigtlander 222, when you're ready to draw some conclusions. I'm interested because I've experimented with another developer with small amounts of chemicals:

http://www.gpaulbishop.com/GPB History/Articles/article_-_2.htm

Note that he's talking about grains, not grams. I've actually doubled the amounts of chemicals at times to try to boost activity. Very fine grain.

 

[Murray Kelly]

Thanks for reminding me of that article, Trask. I remember reading it and wondering what the acetone is for. Later I found out that it acts to raise the pH, so he does use an alkali without realising it.
I just checked - it's ~15gr/g so he's got 2+g /L of SO3 and 1.5g/L of Metol. Now that's even more water than the Voightlander 222
A kind soul has sent me some Technidol which is still in the mail. I will check that out with the Imagelink HQ before I get carried away with the V_222.

Interesting formula. A very lean mix which points out
an advantage very dilute chemistry has over the usual
dilutions; compensation with increased film speed.
Also points out glycin's longevity in solution,
1 gram of preservative. Dan

I too am frugal. FX-1 with 0.5, 5, and 3 grams, metol
sulfite, and carbonate is also very lean. Glycin is
apparently very similar to metol in it's action
although at a higher ph. Dan

 

[Christiaan Phleger]

I used V-222 a few years ago for a magazine fashion shoot involving white wedding gowns in bright Hawaiian sunshine. Worked fantastic, holding the extreme highlights with clean, printable detail. Very nice. I intend to mix it again when I get more Glycin.

 

[Trask]

Murray: one more question -- are you using V 222 as a stand or semi-stand developer (as regards the times you cited) or are you agitating on the minute or every 30 sec? Temp at 68F?

 

[eclarke]

Murray, Riding Waves, You guys hooked me and now I have to piddle around with this V-222!!! Evan Clarke

 

[Christiaan Phleger]

Pulling out my notes, it was way back in 04', I shot on Neopan SS at 100, in V-222, 8.5 to 9 min at 75 degrees. I'm still looking for some tear sheets to show what it looked like. The next batch of Glycin I'm going to try Pan F and Plus-x in 120 in it, maybe use an old uncoated Zeiss Tessar for the old timey look.

 

[Murray Kelly]

Trask, Evan, Riding waves. It's a question I raised, but have had no experience with. As Dan comments, it reminds one of a Beutler with the metol substituted with glycin and at a much higher pH.
Riding Waves has the most experience so far I've run into. As I said, my focus is on microfilm since I have 'a lot' for my 16mm stable. FX-1 wasn't the answer, for me, but this is worth a look from my point of view. OTOH I am also dis-satisfied with my results so far with Kodak Hawkeye B&W in all the usual suspects. Another one to try in it?

Murray

 

[Christiaan Phleger]

Yeah, V-222 does seem in the Beutler style, I've also thought it was a high dilution version of Huble Paste. I seem to recall around that time that I was kinda going thru a 'minimalist' phase, dilute D-23 etc, and I recall finding a web page with tons of old translated German formulas. Most were your basic Ansco 17/D-76 variants but V-222 looked so simple and I just got a new batch of Glycin. My notes state that I did a few tests with FP4 as well, but those didn't look very good or it wasn't the look I was going for. Neopan SS is such a sturdy little film, very hard to not get anything. Still looking for the results of the shoot. It was a bridal gown shoot at the beach (I think) so lots of light and contrast and massive high key. I do also recall that it seemed to have not much shelf life, my notes kinda suggest I mixed and used it pretty quick. More testing when I get another batch of Glycin. You guys keep me posted if you try any, since I only tried it in those 2 films and there are a few other films which might take nicely to it.
