XT-3 - Info on the black and white developer

The Adox XT-3, an innovation in the field of isoascorbate-based developers, delivers first-class results when using all types of film and in all light situations. This balanced developer optimizes the film's sensitivity and delivers sharp, well-defined negatives. It is an alternative to the Kodak XTOL developer.

As a hydroquinone and borate-free developer, the Adox XT-3 stands out positively from older isoascorbate-based developers due to its improved durability. In addition, its significantly improved solubility makes handling easier. Components A and B of the Adox XT-3 solution dissolve completely in just 2-3 minutes.

Equipped with ADOX CAPTURA technology, the Adox XT-3 offers a dust-free approach, thus posing no health hazard when mixing. This makes this developer a safe and effective choice for photographers using the Adox XT-3.

The development times and resulting curves of the Adox XT-3 are identical to those of X-tol in composite bags, which was available until about 2019. Compared to other developers like Xtol, Excel or LegacyPro Eco, the Adox XT-3 offers a number of advantages:

Borate-free
Biodegradable complexing agents
No health hazard when mixing due to the CAPTURA dust-binding technology
Improved solubility
Improved durability

Made in Germany, the Adox XT-3 is an expression of ADOX's commitment to ensure the availability of legendary Kodak photochemicals. After the sale of the Kodak chemical division to Chinese investors in 2020, ADOX launched a program to "secure availability" of these photochemicals. In doing so, ADOX modernizes the recipes and conducts research and quality control at the ADOX location in Germany.

It is important to note that when using the Adox XT-3 and all other isoascorbate-based developers, possible turbidity and color changes should be observed. These developers can lose activity very quickly. If substances precipitate or a significant yellowing occurs, the Adox XT-3 should no longer be used.
