eTone Professional 120 135 Developing Tank With 2 Spiral Reels
This developing tank is designed to handle two rolls of 135/35mm film or one roll of 120 film concurrently. It features two multi-format automatic feed spirals with a rotating, undulating motion that promotes even chemical distribution. Constructed from unbreakable, heat-resistant plastic that resists light leakage and chemical absorption, the tank is washable and reusable. The reel can be adjusted by aligning the halves, turning until you hear a squeak and click, then locking in the desired width. It supports 120, 135, B&W, and color film processing.
Considerations: The dual-reel setup boosts throughput but may require careful loading to prevent overlap. Its plastic construction makes it lightweight, but ensure you handle it with care during changes in chemistry and temperature. This model is suitable for hobbyists and educators looking for a reliable, multi-format solution.
Universal Compact Developing Tank With 2 Spiral Reels
The universal compact tank supports multiple formats including 120, 135, 126, and 127, enabling black-and-white and color film development. It ships with a developing tank and two spirals, making it a flexible entry point for multi-format darkroom work. The compact design suits small spaces or educational labs, while the included spirals are designed for quick setup and consistent agitation.
Considerations: While versatile, this tank may require extra care when switching formats to avoid cross-format contamination. Ensure proper light sealing during loading and unloading, and verify compatibility with your preferred chemical volumes to avoid waste.
120 135 B&W Film Darkroom Kit
This kit provides a complete darkroom setup for 120 and 135 film processing, including a 120/135 developing tank with two spiral reels, plus accessory components like chemical bottles, measuring tools, gloves, and a timer-friendly clock. It supports processing two rolls of 135/35mm films or one roll of 120 film in a single tank, using durable, heat-resistant, waterproof plastic. The kit aims to offer a ready-to-use solution for learners and hobbyists.
Considerations: The kit’s broad accessory mix is beneficial for beginners, but users should confirm chemical compatibility and avoid overloading spirals to maintain even development. Replacement spirals and components are typically available separately if upgrades are desired.
eTone Professional 120 135 Developing Tank With 3 Spiral Reels
This larger tank supports substantial film loads: up to three rolls of 135 film or four rolls of 120 film at once, and it can also process six sheet films with an additional 4×5 spiral reel. It can convert to a two-reel setup to reduce chemical use and extend savings. The tank is described as heat resistant, waterproof, and light-sealing for reliable operation. It also supports wide compatibility, including 120, 135, 127, 220 formats and 4×5 sheets when configured appropriately.
Considerations: The higher-capacity design is ideal for batch processing but requires careful management of chemical volumes and loading order to prevent cross-overs. If you primarily develop two rolls at a time, you can switch to a two-reel configuration to simplify use and save chemicals.
Darkroom Spiral Reel For Paterson Kaiser Tank
Designed for compatibility with Paterson and Kaiser tanks, this spiral reel features a twin-ball ratchet system and is capable of processing one 35/135mm roll or two 120mm rolls simultaneously. The flexible reel ensures quick loading and secure engagement, making it a practical upgrade or replacement part for multi-format darkroom workflows.
Darkroom Developing Equipment Kit
This kit provides a comprehensive set for developing 120, 135, and 35mm color and B&W films, including a developing tank with two spiral reels plus a timer, chemical bottles, changing bag, gloves, and measuring tools. It supports processing two 135/35mm films or one 120 film at a time with durable, light-blocking components and compatibility with common spirals used in many tanks.
Universal Film Reel Developing Tank W/2 Adjustable Reels
This developing tank includes two adjustable self-loading reels designed to fit a range of film sizes. It features wide-mouth filling and emptying, and it ships with two reels plus an agitator for even chemical distribution. Ideal for users seeking quick format swaps and straightforward operation in a compact package.
KODAK REELS Digitizer For 8mm And Super 8 Films
While not a developing tank, this Kodak reels digitizer converts 8mm and Super 8 films frame-by-frame to digital MP4, providing an archival option for footage you’ve developed. It uses a large onboard LCD and supports direct SD card saving, which can complement a home darkroom by preserving finished film scans for easy sharing and backup.
Buying Guide: Key Purchase Considerations
- Format compatibility: Look for tanks that support your film sizes (120, 135, 127, 220, 4×5, and yes, options that accommodate 8mm through compatible reels).
- Reel configuration: Decide between two-reel or three-reel systems based on batch size, and confirm if the tank can be converted to save chemicals and space.
- Materials and sealing: Choose heat-resistant, light-sealing plastics or metal components for longevity and minimal chemical retention.
- Ease of loading: Self-loading or adjustable reels simplify setup, especially when switching between formats or doing frequent changes.
- Accessory ecosystem: Consider kits that include measuring tools, bottles, gloves, and timers for a complete workflow, or plan to source essentials separately.
- Future-proofing: If you anticipate expanding to larger formats (like 4×5 or 8mm digitization), select a tank and reels with upgrade paths or compatible accessories.
- Storage and footprint: Smaller households benefit from compact tanks, while hobbyists with batch processing may prefer larger-capacity units with safe chemical handling features.
