Used in colloidal gold test paperC/TThe carrier of the thread is also the site of immune response.NCMembrane is one of the most important consumables in biological experiments.

SartoriusSartoris nitrocellulose membraneUsage Introduction:

As is well known, the pore size of nitrocellulose membranes(Tomographic velocity),The differences in processes and formulas between different manufacturers have a significant impact on colloidal gold test strips. The most commonly used chromatographic velocity is140s/4cmOn this basis, a faster or slower chromatography speed can be selected according to the sensitivity requirements of the product, and then the membrane with this chromatography speed can be further tested and compared among different manufacturers.

material characteristics:

Uniform thickness, fast liquid climbing speed, and high surface quality.

SartoriusCN140NCIntroduction to nitrocellulose membrane products:

SartoriusThe company uses independently sterile packaging nitrocellulose mesh membrane as a filter membrane for microbial detection. Nitrocellulose material, suitable for microbial growth, microbial revival rate>90%;

The membrane has grid lines for easy counting and does not affect bacterial growth;

The membrane with bacterial colonies can be used as a detection record after drying*Save, comply withGMPrequirement.

Sartorius SartobindDetailed introduction of microporous ion exchange membrane:

Ion exchange column chromatography is one of the commonly used methods in the separation and purification process of proteins. However, due to the inherent properties of ion exchange column chromatography-Some defects. In practical applications, it has complex and time-consuming operations, and the flow rate for processing small samples can only be limited to1-10ml/minWithin the range, excessive flow rate can cause resin damage and other shortcomings, and ion exchange column chromatography can only be used for protein separation processes and cannot concentrate proteins.

To solve this problem, the German company Sartorius specially invented microporous ion exchange membranes(Sartobind^TM)This new technological concept product. This shovel has very high practical value, which can be used in combination with preparative liquid chromatography, or connected to a fast peristaltic pump. For the treatment of small samples, a syringe can also be used, and the purification and high fold concentration of egg quality can be completed simultaneously in one experiment. The microporous ion exchange membrane has strong pressure resistance, high chemical stability, and significant adsorption of proteins(2mg/cm²)Fast flow rate(up to3L/min)Features such as short running time and simple and convenient operation. The use of this method for protein processing and preparation, whether in grams or kilograms, is very simple in all operations.

Sartoriusfrom1929We started producing nitrocellulose membranes in [year], and since then, our production process has been continuously improved to maintain a leading position.

Nowadays,SartoriusThe advanced production process of nitrocellulose membrane fully complies withIS09001The standards are protected and protected.SartoriusThe living room has reached or even exceededCGMPrequirement The whole process of membrane production, cutting and packaging is carried out in the sterile workshop. The production process of technology*Our production workshop, professional film making experience, and consistent strict quality control have enabled our nitrocellulose membranes to perform excellently in terms of performance, quality, and uniformity.

Quality assurance

All membrane products must pass strict quality inspection before leaving the factory. each-All batches of films are accompanied by quality inspection data, quality qualification certificates, and quality tracking numbers to ensure that the films delivered to the user fully meet the quality standards.
