Cellulose Extraction Thimble and Glass Fiber Extraction Thimble

Soxhlet extraction is widely used in the field of solid-liquid extraction, analyzing fats or pesticides in foods and soil materials, and other procedures. Cellulose and glass microfiber extraction thimbles are the key components in Soxhlet extraction, which provide a safe and efficient solvent extraction of solids and semi-solids.

We can find different kinds of extraction thimbles in the market. Which one will fit your need? There are some tips for you to consider if you want to put your Soxhlet extraction into practice.

First, pay attention to the thimble sizes, which should fit the extractors correctly. Remember, when you calculate the external diameters, an extra allowance for wall thickness should be included. When passing through the narrower end of the upper extractor socket, The thimble should have 1-2 mm clearance and should be about 5-10 mm above the level of the top of the siphon tube.

Second, choose the right thimble media. Hawach provides a thimble with cellulose or glass microfiber. Thimbles which are made of high-grade cotton cellulose can fit most Soxhlet extraction devices with their smooth interior surface. The high-purity glass microfiber thimbles are widely used for high-temperature filtration. Scientists also use them when the solvents are not compatible with cellulose thimbles.
Hawach Cellulose Extraction Thimbles for SoxhletThe adaptability of Cellulose Extraction Thimble

Hawach cellulose extraction thimble is a safe, fast, and efficient tool for the extraction of solid and semi-solid substances, especially suitable for the extraction of flammable, toxic, or easily odor-prone solutions. The cellulose extraction thimble is made of high-quality cellulose cotton wool, so it has high purity, high mechanical strength, and a good retention effect. The traditional wall thickness of cellulose extraction thimble is about 1 mm, and particle retention is 10 um, while the thickness of the thickening thimble provided by Hawach is about 2mm, which can greatly improve the retention force and humidity of the sample but also adapt to dry strength or other requirements.

Measurement of Cellulose Extraction Thimble
Hawach cellulose extraction thimble is commonly used for the separation of components from samples of solids and semisolids. The cellulose extraction thimble provides a safe method of extraction with toxic or other noxious solvents. Hawach cellulose extraction thimble is manufactured from a good-quality alpha cellulose cotton linter for high-performance use in air and waste gas analysis. Double thickness has greatly improved rigidity and satisfied wider application needs. Applications are available in the analysis of oils, fats, organics, pollutants, and additives in rubbers or plastics. What’s more, high-purity and binder-free thimbles are offered in different materials. Measurement of cellulose extraction thimble is the standard measurement of inner diameter. Outer diameter measurement can be measured by adding twice the wall thickness plus the inner diameter.
Hawach Additives Glass Fiber Extraction ThimblesThe adaptability of Glass Fiber Extraction Thimble

Hawach glass fiber extraction thimble is made of 100% pure borosilicate glass fiber, which has high purity, long life, and good sustainability. Hawach glass fiber extraction thimble adds no adhesive or additives, is green and environmentally friendly, and is suitable for use in high temperatures or solvents unsuitable for cellulose extraction thimble. Meanwhile, various models and wall thicknesses are provided, and customers can choose the needed one according to various applications.

The resistance of Glass fiber Extraction Thimbles
Hawach glass fiber extraction thimble is designed to fit most extraction units with 100% borosilicate glass microfiber. It can be well suited to pollution monitoring and emission control in the analysis of acidic gases. Moreover, it is available in a wide collection of sizes and wall thicknesses for optimal use in extraction units. Consistent and widely distributed pores guarantee fast flow through and excellent retention ability.
