Features and Applications of Hawach Extraction Thimbles

Hawach offers high-purity extraction thimbles in cellulose for Soxhlet extractions and in glass fiber for the analysis of environmental pollution.

Cellulose extraction thimble application
The cellulose extraction thimble is a high-quality sample container for quality control, research, and analytical applications in which solid and semi-solid solvent extraction must be performed. The use of soxhlet extractors provides a safe method for extraction using toxic and other toxic solvents. It features high-purity materials, consistent physical properties, available in a wide range of sizes, and also fits into popular automatic extraction systems.

The high-purity cellulose extraction thimbles are recommended for the following applications, such as the determination of fats in food; analysis of lacquer and binder in paints; vitamin A and carotene extractions; quality control of ingredients in pharmaceutical preparations; polymer determination in polymer industry; extraction of organic compounds from the reaction mixture.

The Hawach soxhlet extract thimble is made from pure cellulose and can be used for a variety of applications where the original sample is essentially solid. Common applications include extracting fats or pesticides from food and soil materials.

Glass fiber extraction thimble application
The other is the glass fiber thimble which is also a convenient tool for the separation of aerosol droplets and condensates from gases. It can be applied to dust particles and aerosols sampled from the air stream; Soxhlet extraction requires a solvent that is too corrosive for the cellulose thimble.

Purity and Performance
Extraction thimble by advanced cotton cellulose fiber or 100% pure boron silicate glass without adhesive superfine fiber, can ensure the best results. There are a variety of sizes to choose from, to fit most of the soxhlet extractors, providing a safe, convenient, and effective method of solvent extraction of solid and semi-solid.

Hawach soxhlet extraction thimbles are made from pure cellulose, neutral cotton, free of fat and impurities, with good mechanical strength, the full-size range which is suitable for soxhlet extraction of most solid sample types. The manufacture of Hawach soxhlet extract thimbles meets the needs of today’s analytical applications.

Size selection guide
Care should be taken in selecting the size of the thimble for proper installation of the extractor. The different dimensions represent established conventions, showing the inner diameter and total length of the thimble in millimeters. Therefore, the wall thickness should be considered when calculating the outside diameter. The thimble should pass through the narrower end of the upper suction pipe, leaving a gap of 1-2 mm and 5-10 mm above the top of the siphon.
