彩色負片RA漂白NR補充液，2 x 5L（10公升）

Two boxes showed up well packed and that 10 liters total is going to last my lab a long time. The replenisher keeps my bleach bath stable for weeks, and I've noticed cleaner negatives with less washing needed between runs.

The lower replenishment rates are the reason I switched, and the math works out nicely over a month of steady film runs. I’ve cut my chemical waste noticeably without seeing any shift in how clean my negatives come out. It’s a solid investment if you’re running volume.

The 10L size is perfect for a busy lab—we're going through way less of this than the old chemistry we used. The lower replenishment rates mean the bleach stays stable longer, which has cut our monthly chemical costs noticeably.
