We are in the market for a vacuum concentrator unit for a range of applications but one of the challenging ones is drying up to 24 samples of 1:1 water:methanol, with 10mL per sample!
One of the many systems we are lookig at is the Buchi syncore polyvap r48 or even the R96 model.
Does anyone have any experience with this system, such as its ease of use, reliability, adaptability that you would like to share with me?
Thanks
Greg
When you write you have a range of applications, the SyncorePlus from Buchi might be a suitable device, as you can simply change the Racks for another application. Unless you have hundreds of sample per day, I would actually go for the R-48, because you have a higher evaporation area (bigger vessels) and you will be very fast with your evaporation. The installation is easy – heat up the system, insert your samples, cover onto the samples, and start. I know from my experience that water:methanol mixtures are not easy to distill, because they tend for boiling retardations. Therefore, you would choose a slow pressure gradient at first at high shaking. And if that doesn’t help, just ask your local Buchi distributor in down under, they have a Competence Centre and will help you out if you face any problems.
