The SuperMag Separator™ is designed for the separation of magnetic nanocrystals in solution using small volumes in different containers. It is easy to use and portable having a weight of 1.83 kgs (4lbs) and the dimensions 9 cm x 10 cm x 6.5 cm. The opening at the center is designed to hold a 1 cm x 1 cm cuvette that takes a maximum of 4 mL and has the strongest magnetic field. The pair of openings on one side are designed to accommodate 1.5 mL centrifuge tubes while the second pair on the opposite side are designed for 10 mm test tubes. All the opneings can be used for smultaneous separation of multiple samples. The time required for separation increases with smaller diameter magnetic nanocrystals. This product is highly recommended for iron oxide with diameters of 10 nm and above.
