2006-10-25  Nucleic acid separation is an increasingly important tool for molecular biology. Before modern technologies could be used, nucleic acid separation had been a time- and work-consuming process based on several extraction and centrifugation steps, often limited by small yields and low purities of the separation products, and not suited for automation and up-scaling.

2019-8-30  1 Introduction. The migration and retention of fine particles in porous media are critically important to natural processes and engineering applications such as soil erosion (Aitchison Wood, 1965; Jones, 1971), groundwater flow (Ryan Elimelech, 1996), oil production (Khilar Fogler, 1983; Mungan, 1965), and the performance of geothermal reservoirs (You et al., 2015).

Magnetic Reconnection in the Space Sciences: Past,

In space, huge amounts of energy are released explosively by a mysterious mechanism: magnetic reconnection. Reconnection can abruptly convert energy stored in magnetic fields to energy in charged particles, and power such diverse phenomena as solar and stellar flares, magnetic storms and aurorae in near‐Earth space, and major disruptions in magnetically confined fusion devices.

Goudsmit’s double-walled magnetic filters are a good choice for liquid chocolate. The magnets capture fine iron particles from liquid chocolate, cocoa butter or cocoa liqueur.

Magnetic particles for the separation and purification

2006-10-25  In the laboratory, colloidal magnetite Fe 3 O 4 (or similar magnetic material such as maghemite γFe 2 O 3 or ferrites) particles usually are surface-modified by silanisation. Naked iron oxide (Fe 3 O 4) has the capacity of adsorbing DNA (Davies et al. 1998), but aggregates due to attractive forces reduce the surface area that can be used for adsorption.Silane compounds coupled to

Plate Magnets Magnetic Separation Bunting-Newton

Standard Plate Magnets are available with permanent ceramic magnets or with high-intensity permanent rare earth magnets. Both types of magnets work efficiently to capture fine metal particles and slightly magnetic debris from powdery, moist, clumpy, or abrasive materials that might choke or wear cartridge-based separators.

Magnetic Filtration Applications and Benefits

2021-5-7  Particles that are the easiest to separate are large (100 microns vs. 5 microns) and highly magnetic (for example, iron and low-alloy steel). The fluid conditions that best facilitate the separation of magnetic particles are low oil viscosity (ISO VG 32 vs. ISO VG 320 for instance) and low oil flow rate (2 GPM vs. 50 GPM).
