🔬 Lab Update: Buchi Rotovapor, Buchi Lyovapor, and Buchi Flash Chromatograph/Prep HPLC 🔬

I figured I would give another quick lab update. We got a few new things in from Buchi that we will be using a lot over the course of the year. They actually arrived a little while back, but COVID-19 has put delays on installing and using them. I've spoken a few times on here about it, but I have always been frustrated by the lack of reference standards for certain things. There are so many cool plants out there without any reference standards for their active ingredients! So we are left unable to properly standardize for the things in those plants that we want. If Sigma or USP didn't carry the standards, we were kind of out of luck. We were forced to just do extraction ratios and wait for the standards to eventually become available. Well I decided that was not a good enough solution. So now we are building out the capability in our lab for us to create our own reference standards!
Here is the Buchi C-850 dual flash chromatograph/preparatory HPLC with both UV and ELSD detector.
Many of you already know what an HPLC system is. It's a machine that uses columns and solvents to separate out compounds from each other through a liquid mobile phase. Thos…

When you're using the rotary rig, are your just using it for testing samples or for all extracts? Like are entire batches of lemon balm solvents being spun out of that one machine?

It's mostly for R&D work. We are doing our own extractions and syntheses now. This rotory evaporator is not large enough for production batches. Those need 20L or 50L ones. So this one is for us testing out new extraction methods or doing small scale R&D synths in advance of doing larger scale ones.
