The eTone kit bundles a timer clock, multiple chemical bottles, a changing bag, and a two-roll developing tank with two spiral reels. It accommodates 135/35mm and 120 formats, making it suitable for common black and white workflows. The included spirals are compatible with other brands’ tanks, and the three-channel timer supports independent or simultaneous timing. The set emphasizes a complete, ready-to-use darkroom package, though users should check tank seal integrity and follow safety guidelines for chemical handling.
YCCLDIPL Darkroom Film Processing Equipment Kit

This comprehensive kit includes a 135/120 film processing tank with two multi-format self-feed spirals for uniform chemical distribution. It comes with acid-free negative film pouches, safelights, multiple storage bottles, a changing bag, gloves, gadgets, and a three-channel timer. The kit is designed to handle 135/120 formats and supports both color and black and white processing with a focus on safe storage and organization. The manufacturer notes a non-water-tight red cap on the tank, which may require careful handling during cleaning and use.
Universal Compact Developing Tank 2 Spiral Reel

The Jian Cheng developing tank supports multiple formats including 120, 135, 126, and 127. It ships with two spiral reels and is marketed for both black and white and color film processing.

The design emphasizes compatibility with 35mm and 120 formats and is built around a sturdy, heat-resistant, unbreakable plastic tank. It supports efficient loading for simultaneous processing of multiple frames and aims to streamline the BW developing process for hobbyists and semi-professional shooters alike.
Kodak D-76 Developer Powder (BW)

Kodak D-76 is a classic powder developer used for black and white film development when mixed with water. It has broad compatibility with general photo applications and is suitable for normal or push processing. While not a complete kit, it serves as a dependable BW developer option within a home darkroom setup, often paired with a suitable developing tank and timing controls for consistent results across various BW films.
Buying Guide
Key purchase considerations
- Format compatibility: Confirm the kit or tank supports your primary film sizes (120, 135, 35mm, or others) to avoid bottlenecks in processing.
- Tank and reels quality: Look for unbreakable or durable plastics, corrosion resistance, and reels that ensure uniform chemical distribution for even development.
- Safety and ergonomics: A changing bag, safelight compatibility, and gloves are essential for safe handling in a makeshift darkroom.
- Timer features: A multi-channel timer can help manage independent steps or concurrent processes, improving consistency in exposure and development times.
- Chemistry options: Consider complete kits with developer and fixer options, or individual components like developing tanks and powders for a custom workflow.
- KC considerations: Ensure that any included accessories (thermometer, loupe, measuring tools) meet your accuracy needs for temperature control and timing.
- Drying and storage: Plan for a clean, organized drying area and safe storage for bottles and chemicals to minimize accidents and contamination.
For a balanced BW workflow, a combination of a reliable developing tank with spirals, a suitable timer, and a proven developer powder or liquid is typically effective. If you are new to home darkroom work, start with a complete kit that covers the basics, then add precision tools or extra bottles as you gain experience. When comparing options, weigh format coverage, build material quality, and the availability of safe storage solutions to ensure smooth, repeatable results across your BW film projects.
