Hi Scott,
we’ve actually published a follow-up paper to the original that focuses on the bead synthesis on bio-protocols (https://bio-protocol.org/e3394) which contains exactly that. In there you’ll find not only a list with catalog numbers of all used labware but also a picture of the actual set-up (Fig 1A). The bowl for the water bath (no catalog number) is simple heat-resistant kitchenware and we use common mercury thermometers which we put in the water bath.
Let me know, if you’ve got any more questions 🙂
Cheers
Phil
