| May 2, 2017 at 17:52 | comment | added | Asmyldof | @jonk IPA is a common term in Germanic countries, as it defines the active chains, my German supplier of lab grade 99.9% stickers everything IPA, so it sneaked in. Used to call it just (Iso)Propanol. | |
| May 2, 2017 at 17:49 | comment | added | Asmyldof | @K.Mulier Bamboo tweezers are for optics, so you do not scratch them, while bamboo does offer a very good spring force. And they are fun to have laying around when a potential customer comes by. for the ultrasonic cleaner, anything somewhat decent will do. The only difference power makes is the time. The cheapest chinese ones often don't work well (bought 5 to test as "take to customer" devices, all crap), but a small jeweler's one with a few dozen watt of effective power that's somewhat designed should work for small tools. I happen to have several, but again, lab. | |
| May 2, 2017 at 16:27 | comment | added | jonk | I'm a hobbyist only. But if you use iso (iso-prop, iso-propanol, and odd but I can't recall ever hearing it called IPA when I worked in a chem lab decades back) from a garden variety store, do NOT buy the 70%. I'm not sure about the commonly available 91% because I select and use 99%. But the 91% might be okay. Regardless, do not leave the bottle open (it will absorb water from the air and it's bad enough you had to open the bottle, at all) and add some teflon tape as a thread sealant to help seal the bottle. | |
| May 2, 2017 at 16:24 | comment | added | K.Mulier | Hi @Asmyldof , you seem to have quite some experience in this! Please hang around a few more minutes.. So if I get this right, (1) You put the tweezers in an "ultrasonic cleaner" each time - do you have a specific one you would recommend?. (2) You have glass-fiber-plastic tipped tweezers. You say they stick "as bad". But which tip do you prefer among all? There has to be one your favourite. (3) You have bamboo tweezers? Isn't that a bit weird? :-) | |
| May 2, 2017 at 15:58 | comment | added | Asmyldof | @K.Mulier Normal IPA (Iso-Propyl Alcohol) should do and is less dangerous to plastics in the vicinity. I put them in the ultraconic after each project (and have a stock of 10+ tweezers of each type), but then I do run a Freelance lab ;-). I also have glass-fiber-plastic tipped range, and they stick as bad, unless components are para magnetic or such. Same for bamboo (mainly for optics). | |
| May 2, 2017 at 15:49 | comment | added | K.Mulier | Thank you @peufeu . I got a few more questions. (1) To clean your tweezers, do you use some chemicals? Perhaps acetone absorbed in your sponge? (2) Do you use special tweezers? Perhaps antimagnetic - if that would help? | |
