Can’t do without: Al Foil

I have a confession:

I <3 aluminum foil and can’t do chemistry without it.

When I first saw researcher friends using it, I was dumbfounded: what’s up with all the aluminum foil in your labs?

I’ve since become a convert: it’s a cheap, clean, impervious to spills, versatile, multitasking material that no lab should be without. Go out and buy a few rolls right now.  You’ll save money and frustration after only one use.

Here are only a few reasons why you should have a roll at hand in your chemistry lab:

  • Need a smooth, clean, spill-proof surface? Hey, presto! Just roll some out onto your workbench. When you’re done working, cleanup is a snap! Crumple it up, and toss it into the recycling bin. A sheet of aluminum foil won’t let spills touch your bench, is clean, and is a nice smooth surface.
  • Weigh boats.
  • Temporary container. (mine look exactly like my weigh boats)
  • A quick funnel.
  • A smooth surface to pour out a material for setting into a sheet.
  • A place to rest a stirring rod or magnetic stir bar without contaminating your entire work area.

If you have a roll of aluminum foil, you’ll always have all these tools (and more!) nearby.

A few pro tips:

  • Handle your foil with clean gloves – it comes from the factory very clean – keep your grimy fingerprints off.
  • Make a few weigh boats when you start an experiment – you never know when having a few handy places to stash a small part will be necessary.
  • A caveat: aluminum can be reactive, and will react with oxidizers, strong acids, etc., but usually only when in solution – dry powders (what I usually use it for) are generally safe.
  • Aluminum foil has one side that is shinier than the other.  This is due to how aluminum foil is manufactured (when it’s doubled over to prevent tearing at later stages).
