I always recommend that people do residual hypo tests to verify that they get a sufficient wash however. Notice that there's no hypo clearing bath used. And also because I'm using that time to clean up so that I can hang the film to dry and immediately leave the darkroom. I give it extra time to make sure that all the fixer that wants to migrate can, through the entire thickness of the emulsion. But the fourth bath is probably overkill indeed. I do a fourth bath for "safety" in case I didn't do a good job draining the tank one time. It takes longer because you want to get the last bit of fixer out from the very bottom of the emulsion layer. The third bath takes the fixer levels in the film down to "archival" levels. For equilibrium to be extablished the vast majority of the fixer has to migrate out of the emulsion into the water. It works because the volume of film emulsion is so small compared to the volume of wash water. Her father is a famous trot singer, Pyun Seung Yup. They released two singles, TODAY and Never Ever Let Me Go before quietly disbanding in 2015. The second bath actually takes the largest part of the fixer out of the film. BPPOP () is a South Korean 5 member girl group that debuted in August 2013 under BP Story Entertainment and consisted of members Pyunji, Jane, CU, Inkyung and Yujin. I use a minute because it's easier for me and because the extra time really doesn't matter. This doesn't take any time at all really - a few seconds. The first bath is used to get what's left of the liquid fixer out of the tank - the fixer that didn't drain out at the end of the fixing bath. That is, the fixer will migrate from regions of high concentration (the emulsion) to regions of low concentration (wash water) until a balance is reached. What I remember is removing fixer is a diffusion process. I modified this proceedure for my 3010 drum and Jobo CPP-2 use. Yes, there is a paper floating around out there somewhere that describes this sequence and the reasons for it. ![]() Finally, invert the tank twenty times and drain the water away. ![]() Once more drain the water away and refill. ![]() a container of distilled water mixed with Photoflo. Macromolecules 2015, 48, 1404–1411.After fixing, fill the spiral tank with water at the same temperature, +/– 5✬ (9✯), as the processing solutions and invert it five times.

Via coupling of two reactors, direct chain extension of copolymers in a single reaction step is also demonstrated. Upscaling the reactor from 2 to 16 mL allows for production of over 200 g of high-definition material (3000 g/mol, 1.1 dispersity) in overnight operation (18 h), demonstrating that the photoprocess can be run under very stable conditions even for extended reaction times. Next to the commonly used solvent (dimethyl sulfoxide ), also a water-ethanol mixture was used as greener alternative, without any loss in reaction control. A series of monomers, namely, methyl (MA), ethyl (EA), n-butyl ( nBA), 2-hydroxyethyl (HEA), and di(ethylene glycol) ethyl ether (DEGA) acrylate are investigated, all showing high livingness (dispersity in the range of 1.1 and linear first order kinetics) in the polymerizations and high conversions within 20-min reaction time. The synthetic scope of photo-induced copper-mediated polymerization (photoCMP) in continuous-flow reactors is further explored.
