Hello peeps,
wondering if any of you are using Dry heat oven sterilizer? If so, could you share the type or photo? Are you using for glassware and metals?
Also, I cannot find any big enough one to fit my beakers (even 200ml), so wondering, if a normal small baking oven would be enough? I mean, to buy one only for my lab that reaches the desired temperature and sterilize the beakers in that one? What would be the actual different between "lab dry heat sterilizer" and normal "baking" oven?
Thank you!

- How do you "wipe" them with the ethanol? Do you just spritz and let them air dry, or use a towel to wipe them?
- Do you feel ethanol is better than isopropyl alcohol?
- Should one be concerned about an alcohol "residue" and thus follow the alcohol up with some deionized water afterwards?
Thank you!1) I would air dry it in a clean room. If you wipe it, you can introduce debris or other contamination.
2) I think they would be the same in matter of effectiveness. Ethanol is probably harder to get, because it's considered drinking alcohol. So isopropanol is better choice, at least for me.
3) There won't be any residue. Both ethanol and isopropanol will fully evaporate.
I know we are supposed to let them “air dry,” but what does that mean exactly, especially when you want the glasses to dry quickly? (In my experience, it can take more than just a few minutes for the isopropyl alcohol to completely evaporate.). I purchased a drying rack with wooden pegs, but then I realized that I probably cannot disinfect the wooden surfaces. Should I get a drying rack with plastic bags?

You use preservatives for a reason ... your equipment should be clean and you should use aseptic technique, but any microbial contamination you inadvertently introduce should be controlled by your preservation system.
