I've been a photographer for over 25 years now and have constantly battled uneven development. Your tubes give me perfectly even development - and I am quite grateful. C. G.

Simple, Elegant . . . Congratulations! S. W.

BTZS Film Tubes are legendary among large format photographers. Film Tubes are a simple to use rotary processing system that works better because of random two-axis manual rotation not found in any other processing system. The tubes not only spin but wobble in the water bath therefore agitation is truly random.

Now you can mix different films, developers with different processing times and run them all in one run using a minimum amount of developer - only eight ounces per 8x10 sheet - for greater economy.

Includes one 8x10 BTZS Film Tube plus two caps.

Benefits are:

• Even edge to edge development
• Low chemistry usage
• No rolling devise required
• Process different films and/or different times in the same run
• Convenient daylight operation
