  • Set includes: tank, lid, two film holders (New design, Rev 4), baffle set, two caps and O-ring

Why Rev 4? Here's the backstory:
We've been fighting production problems with the current design of the film holders (rev 3). The “thinness” of the plastic causes some of them to warp when ejected from the mold. While they were better than Rev 2, we were still having to discard way too many parts!

Taking one of the lessons learned while testing the SP-8x10+ tray system, we've added texture to the face of the holders (see photos). The texture breaks the surface tension and keeps the film from sticking while letting us to increase the base thickness, eliminating our warping problem.

Unfortunately, there will be a price increase to $96. Frankly, this increase has very little to do with the film holders and more with just general economics. (The SP-445 price hasn't changed in three years.)

We will continue to sell the existing stock of SP-445s with the Rev 3 holders at the old price of $87. (Not many left!)

Customer comment:  
... wanted to take a moment and let you know how completely thrilled I am
with your product. Your instructions were perfect, the tank is fantastic and
couldn't be easier to use, and each of my negatives were outstanding.
... In all
likelihood, I will pick up a second tank so I can develop a
second set of negatives
at the same time.
