I find this homogenizer very user-friendly, it has three stands for 3000 to 5000 rpm which you can easily switch between. The time settings are very easy to adjust as well. It's a small, compact device that fits easily in between other devices on the bench. I wouldn't recommend to use it for high-throughput sample processing, as you can only homogenize up to three samples a time (in 2ml tubes). For small batches of samples, however, this is definitely an asset for your lab! Bertin has a set of protocols available on their website which you can help you to determine and experiment with the settings for your protocol (1x 60s, 3x 30s, depending on tissue types etc.). We haven't had to use after sales care yet, but we do have a good experience with the Bertin customer service and their recommendations.
