SEPAROL

Description

The Separol family , packaged as a powder mixture, without hydroquinone and of course without caustic alkalis.
According to the new, very strict EU guidelines, these developers are not considered environmentally hazardous. The main developer substance is a derivative of ascorbic acid, so there is no risk to health when preparing the developer solution. Separol developers are suitable for all commercially available photographic papers. With Separol NE, Soft and HE, the image tone can be influenced - within the limits of the paper used - by adding an image tone stabiliser included in the scope of delivery.

Despite the absence of hydroquinone, a high maximum blackening is achieved, whereby the entire tonal range, including deep shadows, is finely differentiated.

Two-bath development or fine tuning by mixing NE, HE or WA with soft is possible. When developing in two baths, develop in NE, HE or WA until the mid tones are in place. The highlights are produced in the second bath (Soft 1+5 to 1+10).

Shelf life of stock solutions:
Separol NE, WA, 1-2 years in highly filled bottles or partially filled bottles with inert gas.
Separol SOFT approx. 6-9 months
Separol HE 5 years

Shelf life of working solutions under exclusion of air
Soft 2-3 months
NE and WA 6 months
HE 1 year
