I’d like to try a Betterscanning holder, but the company appears to be defunct. They don’t respond to orders and don’t answer emails.I've used the Epson with a Betterscanning holder
Wow a 10L graduate! How big and expensive is this and are you sure this is not overkill?
$55.

glassware?...California?...earthquakes?... what could possibly go wrong?Yes, but I like lab glassware (even when it’s not actually glass). Chemistry is one of my hobbies and have probably about $5000-$10000 in glassware in my lab.

A Betterscanning holder will not increase the resolution of the scanner.

Lab glassware is a broad term that encompasses lots of things used in, typically, chemistry labs. Beakers, graduated cylinders, distillation condensors, pipettes, volumetric flasks, separation funnels, etc. Oh, and a 60Mhz NMR spectrometer.So what is lab glassware in relation to your link which takes me to what appears to be a plastic beaker that is no different from the the one I mentioned and the even bigger one Matt mentioned?

Sure, I could buy a big orange bucket from Home Depot, but I prefer tools suited to the task. In this case, it’s mixing up 5L batches of a developer. The beaker I linked to is already graduated and will fit on one of my magnetic stirrers. It’s also smaller than one of those buckets and will take up less room in my lab.
I know some people prefer cheap, quick and dirty solutions to tasks like this, but I don’t.
I keep a variety of buckets on hand in the shop. But there are a couple of issues with them when it comes to photo chemistry. The nickel plated bails or handles rust pretty fast in a darkroom sink environment. Second, when they do come with volume markings, those are often wildly off, and are not a realistic substitute for high quality graduated cylinders when it comes to accurate measuring.

I'm not certain that looking at a magnified negative delivers a fully decisive analysis of grain quality. Remember the grain in the final positive image originates from the spaces between the grains of the negative. Actually looking for the spaces between grains and then mentally flipping those spaces from light to dark to form a "positive" judgement has always been too difficult for me. I've got to print a negative to be sure of what I'll get.Viewing the negatives on a light box with a 15x loupe. Compared it to negatives of the same subject on TMax 100 (also developed in HC-110 B).
Sounds like some good points you have made Matt in #167 but it seems as if Drew takes a dim view of a Canadian bucket made out of recycled tires and I must admit that I don't like the sound of "tires" whatever they are
Yes, it’s my lab. I have graduate degrees in chemistry, but no longer work in that field, so I do it as a hobby instead. My lab isn’t as extensive as many professional labs, but it is very well equipped, with a fume hood, sinks, gas lines for Bunsen burners, vacuum line (water aspirators are a bad idea in areas with frequent droughts), etc.Thanks for the reply. Can I ask: is that "my lab" as in you own it or just work in it? Clearly you want to work with the best stuff and that's fine but what happens if you don't find that Xtol gives you what you want with FP4+ . $55 is then a lot of money for very little or no reward, isn't it? Might the money not be better spent on a cheap and dirty bucket which will do the job and spend the rest on TMax 100 which you know works better

In the grand scheme of things $55 isn’t that much, and I can use it for other things in the lab.
......any chance to budget for that new scanner?
If 8L is enough for you, this will do the job as well or better.
