33?100mm Extraction Thimbles

The cellulose extraction cartridges, designed for use in Soxhlet extractors, Tecator or similar devices, are crucial elements in the process of extracting soluble compounds from solid samples. These thimbles function as containers that hold the sample during the continuous extraction process, where the solvent is repeatedly circulated through the sample to dissolve the desired compounds.

The structure of the cartridge is critical, as it usually consists of a cylinder made of a porous material, such as cellulose or filter paper. This feature allows the solvent to circulate while keeping the solid particles contained, preventing them from mixing and ensuring that only soluble compounds are carried away. In this way, the cartridge guarantees an efficient separation between the extracted solutes and the residual solids.

In short, the extraction cartridge:
? Ensures compact containment of the solid sample.
? Facilitates the passage of the solvent without entrainment of solid material.
? Improves the efficiency of the extraction process by adequately separating the extracted compounds.

This component is essential for optimal extractor performance, as it promotes a clean and efficient extraction process. Each cartridge has an approximate capacity ideal for small sample quantities, and is used in contexts where solvent efficiency and speed of extraction are priorities.

33?100 mm cartridge
Suitable for 4 to7 grams of solid sample.
Used for medium to large sample extractions. The additional height allows for greater sample capacity, which is useful for analyses where a significant amount of extracted material is required, such as in testing compounds with low active substance content.
The additional height provides greater volume, allowing the use of more solvent and facilitating the extraction of compounds in moderate sample sizes. This cartridge is useful in studies of low concentration compounds that need longer circulation time.

22?60 mm cartridge
This cartridge is ideal for small quantities, frequently for 1-2 grams of solid sample.
It is used for extractions with small sample quantities where solvent efficiency and fast extraction are desired. It is suitable for analysis of limited sample quantities, such as in laboratory studies where resources are optimised or where expensive or difficult to obtain compounds are involved.
Its small size may make it difficult to extract larger samples and limit the amount of solvent that can flow through the sample, which may affect extraction efficiency for larger quantities.

33?80 mm cartridge
This is suitable for 3 to 5 grams of solid sample.
This is a versatile size that offers a good balance between capacity and extraction efficiency. It is commonly used for medium sample quantities, where the solvent can circulate optimally and good contact with the sample is ensured. It is ideal for research work and laboratory applications where the sample quantity is not excessively large, but efficient extraction is required.
The larger height and diameter allow free circulation of the solvent without the sample being too dispersed or squeezed, maximising extraction efficiency.

The 41?123 mm cartridge holds approximately 10 grams or more of solid sample.
This size is ideal for large-scale extractions, such as in compound extraction studies of plants, foods, or natural products, where a considerable amount of sample needs to be extracted. It is suitable for research work that requires a large amount of extracted material and where large volumes of solvent are available.
Due to its large size, it requires a lot of solvent and circulation time to complete the extraction, which can make the process more costly and time-consuming. It is less efficient for small sample quantities.
