Glass Fiber Extraction Thimbles Usage Conditions
Glass fiber extraction thimbles provided by Hawach Scientific Co., Ltd are imported from high-quality selected high-quality inert cellulose long fiber and cotton fiber. Innovative technology is a highly homogenized model refined, completely free of impurities, uniform pores, stable and firm quality, accurate size, high mechanical strength, and strong retention. Glass fiber extraction thimbles are commonly used in a variety of Soxhlet extraction, rapid solvent extraction or other similar extraction applications and are a safe, convenient and efficient extraction of solid and semi-solid materials. Designed to hold solid samples to be leached (liquid, semi-solid samples are loaded with appropriate solid support after application), placed in a sufficient amount of solvent (usually organic solvent) to provide a complete sample, and solvent Isolation is in an environment where there is sufficient contact, and the leachable components in the sample are separated by dissolution in a solvent. Available in a variety of models and wall thicknesses, it is suitable for a wide range of applications with most soxhlet extraction designs. Hawach extraction thimbles have been selected by the laboratories of major testing institutions, the quality meets the testing standards and can be used as an alternative to imported products such as Whatman brand products, which can greatly reduce the experimental cost and improve efficiency.
Due to the characteristics of glass fiber, the following points should be noted when using it:
1. Before use, check the two slightly blocked and slightly hoops of the sampling head, whether the taper is the same, matching, and whether the gap is suitable. When the extraction thimble is loaded and unloaded, it is not subjected to the force such as tearing force or shearing, so that the filter cylinder mouth is protected from breaking.
2. If the extraction thimble is found to have voids, cracks, and uneven thickness, it cannot be used to avoid sampling failure due to airflow.
3. To be used within the specified temperature range, ensure that the extraction thimbles work at sufficient strength. It has been reported that the glass fiber is heated to above 200 °C and then cooled, and its strength begins to decrease. After the fiber is heated to 510 °C for cooling, the strength is only maintained at 35%. Fibers maintain high strength when heated, but their strength is greatly reduced by cooling.
