Abstract. In this study, the operating mechanism of a Knelson concentrator (KC) is analyzed by considering the concentration mechanisms of dense minerals obtained based on the feed properties, operating parameters, and design parameters of the KC bowl.
Offers increased volume flexibility and performance. Vivaspin™ 20 Centrifugal Concentrator handles up to 20mL in swing bucket rotors and 14mL in fixed angle rotors accepting 50mL centrifuge tubes. Features twin vertical membranes for unparalleled filtration speed and >100-fold concentration.
The bowl of a FALCON concentrator consists of a sophistically engineered system of two sections: The conical stratification zone [S]* and the vertical retention zone [R]*. Slurry is accelerated to reach a high centrifugal velocity and stratified along the steep, smooth wall under semi-laminar flow conditions.
Amicon ® Ultra centrifugal filter devices provide fast ultrafiltration with high concentration factors from dilute and complex sample matrices. The vertical design and membrane surface area provide fast sample processing, high sample recovery, and the capability for up to 80-fold concentration factors.
