ADOX C-Tec C-41 Rapid Kit 1L (Develops 12 to 16 Films)

The ADOX C-Tec C-41 Rapid Kit is a complete color negative development system made in Germany by ADOX. It is the direct successor to the discontinued Tetenal Colortec kit, and it processes every C-41 film on the market.

This is a two-bath process. The kit includes color developer, bleach fix, and stabilizer, which is everything you need to take an exposed roll through to a finished, scannable negative. It works in a standard handheld tank or a rotary processor.

Mixing is straightforward. Every component ships in unified 200ml bottles, and each part makes one liter of working solution. To make the developer, you combine parts 1, 2, and 3 in a jug and top up to a liter. Partial mixing is supported, so you can scale to the volume you actually need.

The kit is built for speed. You can develop at any temperature above 24°C as long as you hold it constant with a water bath. At 24°C, ADOX recommends 16 minutes in the developer and 10 minutes in the bleach fix as a starting point. Lower temperatures can be compensated mathematically.

One kit makes 1000ml of working solution and develops 12 to 16 films. Detailed instructions are included.
