Microdialysis and Ultrafiltration
1996Microdialysis and ultrafiltration are complementary sampling techniques that facilitate acquisition of data in awake, freely moving animals. Because the necessity of blood removal is eliminated, sampling frequency is not limited by animal size. The samples obtained by these techniques usually require no processing for analysis.

Current Protocols in Molecular Biology, 1998
AbstractThe first section of this unit describes dialysis of large‐ and small‐volume samples using cellulose membranes with pore sizes designed to exclude molecules above a selected molecular weight. A support protocol describes preparation of membranes for dialysis.

Recovery of biosurfactants by ultrafiltration
Journal of Chemical Technology & Biotechnology, 1990AbstractUltrafiltration was used in a one‐step method to purify and concentrate biosurfactants—surfactin and rhamnolipids—from culture supernatant fluids. The ability of surfactant molecules to form micelles at concentrations above the critical micelle concentration allows these aggregates to be retained by relatively high molecular weight cut‐off ...

Ultrafiltration of Hematite Sol
Separation Science and Technology, 1996Abstract Ultrafiltration of a laboratory-made hematite sol was studied in a batch cell with an Amicon PM 10 membrane at 298 K. The effects of hematite bulk concentrations (2 to 10 kg·m−3), stirring conditions (0 and 400 rpm), and pressure (50 to 350 kPa) were investigated.

The Accurate Control of Ultrafiltration
Artificial Organs, 1978ABSTRACTAn apparatus has been constructed to regulate ultra‐filtration accurately during dialysis. The principle of the apparatus is that, per unit of time, exactly the same amount of dialysate is introduced into the dialyzer as is discharged from it. The apparatus consists of two isovolumetric pumps connected in line.

Tangential flow filtration has traditionally been scaled up by maintaining constant the filtrate volume to membrane surface area ratio, membrane material and pore size, channel height, flow path geometry and retentate and filtrate pressures. Channel width and the number of channels have been increased to provide increased membrane area.

Improved ultrafiltration processes by partial recycle of ultrafiltrate
Journal of Membrane Science, 1983Abstract The economics of ultrafiltration processes may be improved in certain situations by partially recycling the ultrafiltrate. These situations include purification processes involving the use of additives in the makeup stream or processes where a recoverable product is present in the ultrafiltrate.

Ultrafiltration and modified ultrafiltration in pediatric open heart operations
The Annals of Thoracic Surgery, 1993The capillary leak associated with cardiopulmonary bypass results in an increase in content of water in the tissues measurable by an increase in total body water after cardiac operation. Following work by Magilligan in the 1970s, ultrafiltration was introduced during bypass as a means of hemoconcentrating patients and potentially removing water from ...
