 The magnetic blade is the best way to go in my opinion. You can use the
whole blade numerous times since they are so durable. I am not sure if the
vacuum works with them you might ask your rep. I also ordered both guide
plate sizes. I have the microm that you can control the block temperature
separate from the chamber temp and that is definitely a plus if you are
working with animal tissues or have to do serial sections. anita (no kick
back from Microm I just really like my machine)
