How to Use & Clean an Analytical Balance

An analytical balance is a highly precise instrument used for measuring mass. They're typically designed with an enclosed measuring pan to avoid the influence of air currents.

Do chemists ever use little vacuum cleaners? I'm worried pushing powder around with a brush could just get it stuck in tight spots. I work with zircon crystals that are only 250-500 microns wide, and it's extremely important that a zircon from one sample doesn't contaminate another sample. Our lab doesn't have a vacuum cleaner right now but I think it'd be useful.

@Flounder152, great question. Yes, but they're never just normal vacuum cleaners. You would need a vacuum with filters that don't allow your particle size to pass. Search for "cleanroom vacuum."

Hi! May I know what brush you use to clean the balance? Thanks 😊

@anastasiaadinda8833 It's nothing special, just a cheap bristle paint brush from a hardware store.
