View Full Version : Long lasting paper developer fo Nova slot processor

Hello, looking for paper developer for my Nova slot processor. I tried whatever is available at Henrys or Downtown camera (Multigrade, dektol), but those do not last for long.

Ansco 130. I keep mine in the slot for months at a time. Works fine. I do cover my processor with plastic in addition to the floating tubes to reduce oxidation.

Can you specify what is "not long" in your judgement? Until we know your yardstick anything we say may be of no help at all.

LPD would be the canonical answer. You may or may not like the way it looks.

LPD and Ansco 130 are the long-lived ones. I bought some LPD but haven't tried it yet. I use Ansco 130 regularly and it's amazingly long-lived. You can even keep the working solution for several weeks and use it up to its full print capacity.

Thank you guys for your suggestions. Pentaxuser, dektol will be ok in slot for about one day. Ilford multigrade will be ok for about 1 week. I print twice, maybe three times a month, so if the developer is more than two weeks in the slot, it is no good. It looks that for my infrequent print sessions, I will go back to trays and will use dektol, and discard after one time use. With ilford multigrade at 1+9 dilution, I should be ok to store the developer back to amber glass for the future print sessions?
Also I will try Ansco 130 or Liquidol which I was told it has good keeping property.

I cannot speak for Dektol but if it is useless after one day in a Nova slot then I am surprised it sells at all. I do have experience of Ilford MG developer and my experience is that it lasts much longer than a week
I take it that you have the tubes that cover the liquid when not using it? These tubes prevent almost all the air getting to the developer. In effect they act like the amber glass you speak of. In fact unless the amber glass is full, the tubes over the slots will protect the developer better.
I print only occasionally as well and while I have never needed to do this, you could try the following: After placing the tubes over the slots, cover them with cling film, ensuring that no air gets to the liquid.
I hope the Ansco and LPD work for you but I cannot help feel that something else is wrong if Ilford developer is no good after the times you state.
The tubes are vital. Can you confirm that you have these and use them?

Thank you Pentaxuser for your input, much appreciated! My processor is a basic Nova Monochrome model, with a red cover, which is not really air tide at all. Perhaps that is why my Ilford MG is loosing its power after one week? I love an idea of using Nova processor in my tiny darkroom, but I need to get a better paper developer or new Nova processor with a proper cover. I was thinking of getting a new processor from Nova, but the cost of the unit itself and the shipment to Canada is rather very high... so, searching eBay for a used one :)
But for now, I will try different developer (Ansco 130).

If you can't seal the processor, then bottling the developer between sessions should work. Doesn't need to be amber glass, just use PETE (softdrink bottles) and squeeze all the air out.

In mine, Liquidol lasts long enough to start growing things.
Moersch Neutral lasts almost as long. That's just using the floating covers.

These tubes are nothing special. Any plastic tube of the right diameter will do. It should be wide enough to sit on the top of the slot where it widens. Cut it to length and then cut the end at about a 45 degree angle. This is simply so you can get your finger in the tube to hook it out.
Is yours a 10x8 slot processor? If so I or another user can give you the measurements of length and diameter. A hardware store that keeps plastic tubes should be able to supply them

Also I will try Ansco 130 ....
the only place to get glycin is through the photographer's formulary in montana
they can sell you a formulary 130 kit which is ansco 130 ... mix it right away,
unmixed, the glycin will spoil after a while, even frozen and bagged, and sealed
... mixed as a stock solution i have some that is a year 4months old
and works very well, mixed/dilute some say it lasts about 30 days in a tray, i've used some that was
BLACK as coca cola and it worked great ... i've never used ( or ever seen ) a slot processor ..
have fun !

I used to run a Nova Tri-mate, and learned to use Ethol LPD in it, plus a piece of 3/4in plastic pipe for a lid, for longevity. Ethol LPD lasts a very long time especially if it is rebottled and air kept out between uses.

Calbe N-113 / Adolux:Adotol also last a very long time.

Another vote for Ansco 130/Formulary 130. I've used it in my 16x20 Nova for months at a time without going bad. You'll probably exhaust it from printing before it goes bad in the slot.

E72, neutol and moersch eco. 3 months for the later here on a clubmate.
