8x10 BTZS B&W Film Processing Tubes (set of 3)

  • $74.95


This set includes 3 8x10 tubes with caps + 3 extra caps


BTZS 8x10 Film Tubes are a simple to use B&W 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.

Please note the 8x10 BTZS Tubes can be used to also process 5x7, 4x10, 4.75 x 6.5, 6.5 x 8.5, 7x11 & 5x12 film.

For processing instructions, please see the youtube.com instructional videos below.


Now you can mix different B&W films, developers with different processing times and run them all in one run using a minimum amount of developer - only eight ounces per 8x10 B&Wsheet - for greater economy. Set includes three 8x10 BTZS Film Processing Tubes and six caps. The extra caps let you conveniently change caps in the dark.

BTZS Film Tubes work best in pair, so i suggest you order at least three tubes. BTZS Film Tubes are also available as a kit for 4x5. 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
For conventional B&W films only
