Cryolys Evolution - Cooling System for Thermo-Sensitive Samples by Bertin Instruments

"The functions of the Precellys evolution are great for our purposes, which mostly involve homogenization of various tissues for the purposes in Trizol for subsequent RNA isolation and gene expression analysis. However, I have a few grievances. As many scientists use Trizol/Tri-reagent for the purposes mentioned above, I was very disappointed to find that the lid and sample racks of the Precellys are not Trizol-proof, meaning they've developed many pockmarks and streaks because no matter how well you have tightened the homogenization tubes, there is an occasional leak. Additionally, the 7mL and 15mL tubes that the Precellys uses are great for their instrument, however, there are very few commercially available racks to stably hold large numbers of tubes (>20). There are centrifuge adaptors for centrifugation of the 7mL tubes, however there is not a corresponding adaptor for the 15mL tubes. The 15mL tubes fit into a 50mL conical adaptor for a bucket rotor, however, getting them back out is a problem. The "solution" of dumping the Precellys tubes from the bucket rotor is counter-productive to the centrifugation just performed."
