Small Particles, No Loss of Volatiles
Application Area: sample cryomilling
"We have used this cryomicromill for about a year now and have great results. Achieves a uniform, fine powder in minutes. We also have not noticed any contamination for the milling components. The unit does use a fair amount of liquid nitrogen for initial cool down, but it is fairly conservative once sample grinding is conducted. Definitely buy spare grinding tubes so that you can increase the duty cycle while waiting for the previously ground sample to warm up to be removed from the tube."

Makes great lysates, but can easily become inoperable.
Application Area:Preparation of Yeast Lysates
"This mill is versatile and creates a reproducible product every time I use it. There is a large amount of time and liquid nitrogen spent in prepping the machine, so using it over traditional methods doesn't save time. It is very efficient in generating lysates that are consistent and reproducible. The big downside to this piece of equipment is that the on-board electronics tend to seize if the unit becomes too cold, which is very easy when using liquid nitrogen. Typically, the machine can be used for one run before it must be completely warmed up to room temperature before subsequent use. This model can handle up to 20 grams of material at a time with the right accessories, so they can alleviate problems with downtime."
Manufacturer's Response“ Thank you for your review. We are sorry to hear that you experienced difficulty using our product. The model you referred to is an older model that we no longer sell. Upon evaluation of your unit our service technician determined the problems you encountered were related to a power supply problem and was not caused by liquid nitrogen. Our Freezer/Mills are fully insulated and are designed to run continuously with liquid nitrogen without affecting the control panel. We look forward to your continued usage of the repaired mill. Feel free to contact us if you need anything else. “
The 6775 Freezer/Mill® is a small cryogenic mill that processes samples ranging from 0.1 - 5 grams.
Specifically designed for cryogenic grinding and pulverizing of tough and/or temperature sensitive samples immersed in liquid nitrogen. The new high resolution display is user-friendly and shows the each stage of the grinding process. It also shows the Run history, Training videos and manuals and a complete listing of accessories.
