Comparative Advantages of Glass Fiber and Cellulose Extraction Thimble

When you separate the desired compounds, Hawach extractor thimbles can help you minimize your handwork. The perfect design of the round-bottom guarantees the optimal purity for your applications. The factor of high retention can not only prevent certain elements from escaping, but also get consistent results.

Made of high-purity cellulose fibers or high-purity borosilicate glass fibers, Hawach extractor thimbles are recognized as the ideal tool for solid-liquid extraction studies, such as estimating fats in foods and analyzing lacquer and binders in paints. By offering different kinds of fibers and different wall thicknesses, Hawach extractor thimbles can help prevent the equipment from failure by fitting almost all the common apparatus.

Advantages of Work Performance

High-grade alpha-cellulose and seamless noble cellulose are used as the main materials of the cellulose extraction thimble, while the glass fiber extraction thimble uses high-purity borosilicate glass fibers as materials, and all materials are completely free of additives and inorganic binders.

Superior materials endow them with many unique merits, such as better permeability, compatibility, and adaptability. In common conditions, the cellulose extraction thimble can work well under 100℃, while the glass fiber extraction thimble can work well at temperatures up to 500°C. The glass fiber extraction thimble can also accommodate solvents incompatible with the cellulose extraction thimble without damage.

Advantage in Maintenance

In general, glass fiber extraction thimbles and cellulose extraction thimbles have a smooth interior surface, consistent wall thickness, and high porosity. The above characteristics give them good mechanical strength and retention ability, and both of them have good external force tolerance.

In the cleaning process, gently wipe; do not brush hard, or the inner wall will be damaged. Compared to the cellulose extraction thimble, the inner wall of the glass extraction thimble is more tolerable and easier to clean. And the glass fiber extraction thimble possesses the same property as the filter made of the same materials.

Potential Risks in the Cleaning Process

The long-term operation of the cellulose extraction thimble will cause the thimble to be blocked by impurities, which will reduce efficiency, increase energy consumption, and shorten life. If the impurity cannot be removed in time, it will expose the thimble to the risk of scrap replacement.

For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, and chemical cleaning have had many problems in cleaning the thimble, for example, the sediment such as scale cannot be completely removed, and the thimble is corroded, and the residual acid produces secondary corrosion, which eventually leads to the replacement of extraction thimble.

Cleaning Method of Cellulose Extraction Thimble

If the cellulose extraction thimble is cleaned properly, its service life can be greatly improved. A high-efficiency environmental protection cleaning agent can be used to avoid the above situation, which has the characteristics of high efficiency, environmental protection, safety, and no corrosion. It not only has a good cleaning effect but also has no corrosion to the thimble, which can ensure the long-term use of the thimble.
