Invitrogen MX7 Mixer


Invitrogen MX7 Mixer

Semiautomated Immunomagnetic Separation (IMS)


The Invitrogen® MX7 Mixer, U.S. EPA-approved for Method 1623 (PDF, 92 KB), automates the steps of the Cryptosporidium and Giardia magnetized mixing isolation protocols, creating a semi-automated IMS method.


The only protocol change from your existing method is the use of a rotator instead of manual rocking, making it easy to incorporate the Invitrogen MX7 Mixer into your workflow. The same magnetic separators are used, but the MX7 Magnetic Mixer significantly reduces the risk of repetitive strain injuries. In parallel studies performed by independent laboratories, data produced using the MX7 Mixer were equivalent to those obtained following the standard IMS method.
