Flash Purification System Features New Columns that Reduce Solvent Use

The Biotage Selekt flash purification system boasts high-flowrate and high-pressure capabilities that enable fast separation. The purification system is compact and has a small bench-top footprint. It utilizes the company’s new Sfär columns, which can be mounted either on the side or on the front of the instrument and contain high-surface-area spherical silica with a high loading capacity. This allows operators to select a smaller column to perform a given separation, reducing both the amount of solvent used and the cost of the separation. The columns can be liquid- or dry-loaded, opened, and used in conjunction with the company’s Samplet cartridges for optimum chromatography. Various media are available, ranging from 5 g to 350 g sizes. The system features a large touch-screen interface, and the intuitive controls are easy to use for operators of all skill levels.


Material Separator Reduces Water Consumption

The gravitational-inertial classifier (GIC) air classifying system automatically separates dry materials without using water. This replaces the traditional wet separation processes that often consume millions of gallons of water daily and reduces operating costs, streamlines operations, and eliminates the need for settling ponds. The pneumatic air classifier harnesses gravitational, inertial, centrifugal, and aerodynamic forces simultaneously to separate particles at any cut point from 63 μm to 300 μm (50 to 230 mesh). The proprietary, heart-shaped design passes a current of air through a curtain of falling material, and the air directs each particle toward a series of vanes. Coarse particles are discharged while entrained fine particles are recirculated in an eddy current until they are discharged and captured by a dust collector. The system contains no moving parts, which virtually eliminates maintenance requirements and permits unattended, continuous operation. The device is suitable for classifying sand, crushed stone, cement, salt, lime, soda ash, and a variety of aggregates and minerals.
