I get excited when I find convenient containers usable in the lab. For instance, I loooove the boxes that new optical filters come in (e.g. from Chroma). They are sturdy and have little metal closing tabs you can bend over to keep the box closed. Perfect for storing, well, anything!
I hoard these.
Second place for the coolest-boxes-in-the-lab goes to the ThorLabs “Lab Snacks” box. First, you get snacks, then you have a nice little closable box that you can store samples or small parts in:
Probably the most available (and the most used) box in our lab is the pipet-tip box. They’re great for secondary containment for sample vials and for segregating samples. I use them all the time:
In fact, we hardly ever throw any away, which is why we have this pile:
Maybe I should take a trip to the recycling center someday soon, before it gets any more trouble-with-tribbles in here!
OK, so what are your favorite boxes?
