Reliable Plate Shaker

This shaker has a large speed range and can run on a timer. I like how the timer is loud enough to hear across the lab. It also does not take up a large space on the bench. I also like how there are a number of attachments to hold varying things. I know we can use this in incubator and refrigerated spaces, but never have. I mostly use this for enzymatic assays to prevent aggregation.
