The Gardco Automatic Drawdown Machine was designed to draw down membranes with a high degree of reproducibility.
A thermo-analytical technique, in which the difference in the amount of heat required to increase the temperature of a sample and reference, is measured as a function of temperature. This particu-lar instrument has a temperature range of (-140°C - 600°C).
Spin coating is a procedure used to deposit uniform thin films to flat substrates. The substrate is rotated at high speed in order to spread the coating material by centrifugal force.
The NEU Nanofibre Electrospinning Unit uses electrospinning techniques to safely and easily produce nanofibers with diameters of 50 to 800 nm.
The TOC analyser adopts the 680°C combustion cata-lytic oxidation method, developed by Shimadzu. While providing an ultra-wide range of 4 μg/L to 30 000 mg/L, these analysers boast a detection limit of 4 μg/L through coordination with NDIR.
A feed solution passes through the filter membrane directly, with pressure applied from above. Molecules or materials that are smaller than the membrane pore size pass through the membrane.
A feed solution passes to the filter membrane in the cross-flow membrane cells. Molecules or materials which are smaller than the cross-flow membrane's molecular weight cut-off (MWCO) or porosity pass through the membrane as permeate.
