A vibrator is pretty useful in the lab. I suggest a unit designed for hand held massage but if in doubt about which model to select just ask the clerk in the adults only shop which model they prefer…
For instance when packing a column with silica gel, instead of banging a cork ring around the top of the sep funnel to help pack the column I can hold the vibrator against the funnel or the stand and get the whole mass of dry gell churning around a bit from vibration. Then hit the vacuum and that column will pack down MUCH better than any other method of packing I have tried. The vibration allows the gel beads to orient themselves duirng the brief packing interval and it takes just a second.
Another use for the massage wand is during seperatory funnel seperations. My process does not use saline. I skip that procedure in favor of other techniques that accomplish more or less the same thing. However when miixng water into hexane as I do with LLE the water can and will bead up on the glass surface of the funnel. Funnels are hard to clean and this makes it worse if the funnel is a bit filthy lolz. The massage wand held against the clamp stand will vibrate those water pockets down off the sides of the glass so they can fall to the bottom. It is a cleaner seperation but admittedly this is a nit picky sort of thing but nit picky is not altogether bad.
I also keep sheets of fiberglass matt normally meant for hobby use and models around. This is so I can cut them up into whatever shape is needed and the matt handles like a blanket. You often see in my vids fiberglass tucked in places all around whatever lab I am doing involving heat. I use the fiberglass like a babies blanket and wrap stuff loose in it to conserve heat. The downside is fiberglass strands and such can get in stuff but the cloth like material is great for a heat wrap.
The advantage is it is dirt cheap and can be wrapped around anything a cloth can cover so even in tight spots on a SPD head can be wrapped.
A boxed set of xacto knives has proven well worth the investment for this stuff too. Not so much the sharp edge but the flat edged knives are great for scraping off of smooth glass.
Reinforced silicon matts are invaluable. I can pour extract while hot onto a matt while cleaning and once cooled off a small scraper will remove the stuff easy. They are cheap and usually reinforced with fiberglass strands. I got mine from Amazon.
