ADOX is the world’s first photochemical manufacturer, established in Frankfurt, Germany 160 years ago. Throughout all of its existence, it has been a family-owned business, led by generations of chemists focused on photography. ADOX products are now hand-made in own factories in Berlin, Germany and Marly, Switzerland by a small, young and passionate team, bringing innovation and creativity to the analog community.

The ADOX C-TEC 41 Color Negative Developing Kit is the successor to the Tetenal Colortec Kit. It is designed for use with a handheld tank or rotary processor. This kit consists of a color developer, bleach-fix, and a stabilizer for the development of all C-41 color negative films.

The kit yields very fast developing times. It can be mixed easily because all parts are unified to 200ml bottles, and each part makes 1 Liter of working solution. Partial mixings are possible. You can use any given temperature above 24°C as consistent temperature is maintained.
