We've just taken delivery of our latest piece of hi-tech lab. kit.
It's a lovely extra large pestle and mortar for breaking up soil, made to order from recycled oak kitchen worktops by Terry Vaughan (http://www.turnedwoodenbowls.com/). Far cheaper than buying a ceramic one from VWR or Fisher and far more satisfying to have in the lab. as well. Cheers Terry, good job.
