I use 4 small reusable drink bottles. They are a quart in size (or litre). They have wide mouths, screw-on lids, and a snap cover over the spout. I premeasure my chems (dev, stop, fix and HCA) so when it comes time to add them, I just add the entire container. Having them premeasured also allows me to play with temperatures more easily (less to bring up or down in temp). I have a small washtub that I can fill with the proper temperature water (for maintaining or adjusting temps). I drop in my small bottles and allow temps to adjust. Every now and then I will pick up a bottle, swirl the chem inside and measure the temp. It might take a little bit for temps to come in. In the meantime, I finish up my other prep work (dig out my timer, prep the darkroom bag, etc). When temps come in, it's developing time!(posted 8410 days ago)Don't be in such a hurry to get things done. Take your time and you can better guarantee your resultes.
