Filtration

At Carl Stuart Ltd we represent Whatman, recognised as an experienced manufacturer of chromatography products, including chromatography paper, chromatography separation media, High Performance Liquid Chromatography (HPLC) columns, and thin layer chromatography plates.

Today's pharmaceutical, chemical, and biotechnology industries are facing demands for purity, in the development of commercially important products. As a result, chromatography has become a major purification technique, on both a process and preparative scale. Separation media, with guaranteed uniformity and reproducibility, have become vital components in bringing new products to market. Through Whatman, we can provide you with a complete line of chromatography products to suit these exacting requirements.

We also offer an extensive line of Whatman filter papers. The unique features of these filters make them the optimum choice for many filtering techniques. Whatman maintains a guaranteed quality, reproducibility, and uniformity for all its filters by using only the highest quality raw materials. The filters are tested for basis weight, thickness, air flow, and mechanical strength. In addition, special parameters such as pore size, wicking rate, filtration performance, and surface characteristics can be measured as required.

Working with Whatman, we provide you with a range of membrane filters, which with their advanced technical specifications, makes them today's preferred choice for a wide range of applications. The membrane filters offer accurately controlled pore size distribution, higher strength, and flexibility, ensuring reproducibility and consistency. The Whatman membrane filter range includes pore sizes of 0.02 to 5µm, with a wide selection of membrane filters. Sterile and autoclave packs are available for specialized applications. Coloured and gridded types are also available.

Our Whatman disposable filtration devices are designed to enable filtration of many types of samples. They are available in a wide variety of filter choices, with a polypropylene housing, and utilize the most advanced construction methods and design features. This level of engineering provides for the finest disposable filtration devices possible.

In addition, we supply a broad range of high-quality Whatman products for microbiological quality control in the food & beverage, pharmaceutical, and water testing industries.
