I'm not worried about saving money nearly as much as . Solids & Hollows Sterilization Guide for Lab Autoclaves. Learn how laboratories and research facilities can properly sterilize all of the instruments, materials, and media to run their experiments and daily tasks?

Storage/Stability Solutions can be autoclaved for 15-20 minutes at a maximum of 121 °C. There will be some hydrolysis to glucose and fructose, depending in part on how rapidly the .
I just got my new LBT hardness tester and gave it a trial run. Very easy to use and the results seems very consistent. I thought about getting the Lee tester which is cheaper but I didn't want to do a magnified check and interpretation of results.

What lead hardness testers have you used and especially liked? Any downsides to any of the popular models, or any extra good models available? All information will be most appreciated!
which pencil lead is hardest
There were rave reviews of the lead hardness tester formerly manufactured by Cabin Tree and I went in search of one. They sold that portion of the business to ST Machining Products. Does anyone have an opinion on the new model that they are manufacturing? Last fall, I bought a Lee hardness tester for some testing of different alloys and how fast they age harden. well, two weeks ago, I finally started my alloy testing, which includes lots of hardness testing. after several tests, I realized my microscope stand was a poor design, though when I posted photos months ago, I use my HR-150C Rockwell hardness tester for testing lead. I made a indenter with a 1/2" ball, then measure the diameter of the impression and calculate from there. That method seems pretty good comparing to pencils, and .

I thought about getting the Lee tester which is cheaper but I didn't want to do a magnified check and interpretation of results. The SAECO and Lee seem to match pretty well when I use the Bhn vs SAECO curve that is posted at the Castpics site. The Lee matches the method and is similar to the large size industrial hardness testers I used to have access to in . Based on recommendations received on this board and my need for both a lead hardness tester as well as a run out testing device, I ordered the Cabine Tree Dual Purpose Tester. I received it today and found it to be an interesting piece.
The Cabine Tree is easy to use and you can test ingots or larger chunks of lead with it. I've never used the Lee or the Saeco. Knowing the hardness is nice but it really does not tell you the alloy.
I have the earlier Saeco hardness tester with graduation marks with numbers and the sticker still on the body. Yours does appear to be a copy of same. The body diameter of my Saeco is 1.00 inch, and the body (minus the adjusment screw) is 4.320 in length. The Saeco label reads: Saeco Lead Hardness Tester U.S. Pat.

Do not place materials that are not autoclave-safe in the autoclave (i.e., non-heat resistant plastics and glass), as they will melt or shatter during the sterilization cycle. Oxidizers + Organics + Heat = EXPLOSION!And yes, it's quite autoclavable. So are polyphenylene sulfide (PPS), polysulfone (PSU), and polyether sulfone (PES). These and other thermoplastics are readily machined, injection molded, or 3D printed.
