Gevaert 230

[piticu]

Hi. Does anybody knows the formula for G230 x-ray films developers? Many thanks in advance.

 

[Mike Wilde]

I just picked up a pack of 100 10x12" blue sensitive Kodak xray film, but have not had time to test it yet.

It does have a reputation for high contrast, so dilute developers are usually feasible. I have read about some using Ansco 130 at 1:20 for 5' or so. I mix this developer for prints, and it is very resisitant to aerial oxidation, so that makes some sense when working it in open trays, and the dilition to allow develop by inspection. Dim red safelight will work with blue sensitive and green sesnitive xray films.

This information was garnered from this site by typing 'x-ray film' into the search box in the upper right part of the screen on this sites page.

What has to do with Gevaert 230 formula, Mike?

 

[Mike Wilde]

Film is film. Any developer will work in some manner on this xray film.

 

[Rick A]

Most of the posts I've read on another site recommend D-76 for xray film, no matter if its green or blue base. be advised, red(or any) safelight will fog xray film, so it must be handled same as regularfilm.

 

[Mike Wilde]

As to safelight for develop by inspection, I should say, for a few seconds, after more than half of the developing time has elapsed. Look up posts by Nyz I think is his handle.

I don't have G.230, but this may be close:

Gevaert GD-505 radiographic film developer

Metol 1.9 g
Sodium sulfite 71.1 g
Potassium metabisulfite 4 g
Hydroquinone 7.6 g
Sodium carbonate 36 g
Potassium bromide 4 g
WTM 1 l

Develop 5 minutes

I'm not aware of Gevaert 230 developer. Here are a few X-ray developers I have listings for.

Since the Agfa /Ansco /Gevaert formual numbering is messy - I'm wary of vouching for numbering om Ansco, Agfa Gevaert etc....

-------------------------------------------
Agfa / ANSCO 30 X-ray and Aerial film developer
Water (125F/52C) 750 ml
Metol 3.5 gr
Sodium Sulfite (anhydrous) 60 gr
Hydroquinone 9 gr
Sodium Carbonate monohyd 40 gr*
Potassium Bromide 3.5 gr
Cold water to 1.0 L
Use full strength.
X-ray developer, fast and energetic 5 - 6 min.
Non X-Ray films 8 minutes
aerial films,10 to 15 minutes depending upon the type of developing machine.
also suitable for AERIAL FILM, as it is clean working, has long life and gives high contrast.

----------------------------------------------
Agfa 31 Tropical X-ray and Aerial film developer
Water (125F/52C) 750 ml
Metol 3.5 gr
Sodium Sulfite (anhydrous) 60 gr
Hydroquinone 9 gr
Sodium Carbonate monohyd 40 gr
Potassium Bromide 5 gr
Sodium Sulfate 100 g
Cold water to 1.0 L

Tropical x-ray-developer, 2-3 min/30°C, 3-4 min/28°C, 4-5 min/26°C

------------------------------------------
Agfa 35 Pyro Fast X-ray developer
Part A
Sod Sulfite 100 g
Pyro 100 g
Part B
Sod Hydroxide 60 g
Pot Bromide 100 g wow this looks like a mistake
Fast X-ray developer Mix 1 part A with 1 part B, usable 30 min/ Energetic

----------------------------------------
Gevaert G.209 X-ray and Aerial film developer
Water, 125F/52C 750 ml
Metol 4 g
Sodium Sulfite anhyd 65 g
Hydroquinone 8 g
Sodium Carbonate anhyd 45 g
Potassium Bromide 5 g
Cold water to make 1L
Use undiluted
Starting point development time: 5 - 6 mins.

Replenisher for Gevaert G.209
Water (125F/52C) 750 ml
Metol 6 gr
Sodium Sulfite anhydrous 70 gr
Hydroquinone 20 gr
Sodium Carbonate monohyd 70 gr
Sodium Hydroxide 10 gr
Cold water to 1 L
Use full strength.
Replenishment rate keep liquid level.
Mix the sodium hydroxide separately in a small amount of cold water. Then stir into mixture slowly.

---------------------------
Gevaert G.242 X-ray rapid film developer
Water, 125F/52C 750 ml
Metol 12 g
Sodium Sulfite anhyd 80 g
Hydroquinone 35 g
Sodium Hydroxide 30 g
Sodium Carbonate anhyd 30 g
Potassium Bromide 20 g

Add chemicals in specified sequence.
When mixing, due to the risk of heat reaction, dilute sodium hydroxide separately in a small amount of cold water then stir into mixture slowly in sequence.
Use undiluted

Thank you all for your help.

I'm still interestested in that particularly xray developer (I'm not going to use it, my interest is purely theoretical).

The problem with the Agfa (& Orwo) numbers and Agfa Ansco/GAF numbers is due to many errors in US publications mainly going back to the Photo Lab Index's who called Agfa Ansco - Agfa and didn't bother to delineate between two separate companies.

Even the very few Agfa and Ansco Agfa developers which share a common number (and apparent formulae) can be variations due to the type of Carbonate/Sulphite used, and what's worse is the substitution of Monohydrated Carbonate for Anhydrous isn't calculated. (Agfa & Agfa Ansco/GAF 30).

Gevaert's formulae were quite different, they also manufactured Voightlander's films & chemistry.

You've seen this?

Doesn't help in your quest, but verifies that you're not chasing a ghost. That developer really did exist!

Yes i've seen that; i've also found a distributor in Ukraina that still sells it: http://oniko.ua/os/eng/medagfa.shtml (by mid-page)

Interesting - most of the products name there are links to the Agfa website (G230 is not!). If you go to the developers listed on the Agfa website, they discuss how environmentally friendly they are... but G230 is not listed. So I'm going to guess it's not very environmentally friendly. And it's not listed on any of the various countries' versions of the website. And yet it's still sold in the Ukraine, where they may not yet be as concerned with the environmental impact of X-ray processing chemicals...
