![]() What you need to do is feed the film into the outer edge of the spool at the start of the spiral and feed it in a few inches. The reels twist and have a little ratcheting motion in them. For 35mm film make sure you cut off the “tongue” so you have a square edge. There is a knack to it but it is pretty easy. Practice the film loading in the daylight with junk film or a roll you sacrifice for the purpose before you try it in the dark. Darkness is like security, it’s all about layers. The room may not have been perfectly dark but the cupboard in the dark was pretty dark. For the longest time I loaded my film in a room with no windows in the cupboard under a bedsheet at night. After this step it’s all daylight, though so don’t fear. The Blix bottle has my funnel in it because I will be pouring back into it when the timer goes off.įirst step needs to be done IN THE DARK. The Developer bottle is back in the bath water keeping warm and has one of my thermometers leant against it telling me the temperature of the water bath. The Blix bottle is on the ledge there with very little chemistry in it because all that chemistry is in the Patterson tank with my roll of 120 Kodak Portra 800. Here’s the decode to that picture: On the left is my iPad in a non-slip silicone case with LabTimer running. Go ahead and set it up with the following four timers: ![]() Go ahead and download it while you are reading this. You really want this app for your iPad or something similar. You will be pouring the chemistry back into the bottles and you will want to do it quickly. The funnel is necessary because the chemistry is re-usable. I found these “spirit” thermometers are pretty quick. Squeeze the bulb and as long as you are not a vampire the temperature should start going up. I chose thermometers that were long (for easy use and easy reading) and that were fast. This is where your good thermometers and bathtub come in. The later stages of Blix and Stabilise are not as critical. Of this the most important stage is the Development stage. The whole thing should take place at 39 degrees C plus or minus 1 degree. I also have two beakers that I found I didn’t need but they come in handy for holding the thermometers and funnel.Ĭ-41 chemistry is very temperature sensitive. I must have spent close to $20 on decent lab quality thermometers and a good lab quality glass funnel. ![]() The next thing you need (in addition to a bathroom with a bath and sink) is a good thermometer (or two) and a good funnel. If you can keep them airtight, cool and dark they will last longer than your nerve to keep using them! My current batch was mixed more than six months ago. Light, heat and oxygen are the enemies of your chemistry. I store them in boxes in a dark cupboard. You will notice that the glass is not brown or opaque. I replaced them with some laboratory stoppers that are. They came with some cheesy glass stoppers that were not airtight.
