Heads up for chem people looking for free stuff: I asked Macherey-Nagel for a sample of their two color TLC plates (they fluoresce in 254 & 3something nm, sounds cool!) by sending a comment in to their "you have questions about this product" form and someone got back to me and said they would ship me a box of them. Usually you get 1-3 plates for samples (a box usually has 20 if we're talking full sized plates) so I was skeptical, but I just saw the tracking information and it says 4 kg, which is about what a full box weighs...
If they make anything you'd like to try worth asking for samples I guess?
