33?80mm Extraction Thimbles

Extraction cartridges, made of cellulose, are indispensable elements for Soxhlet extractors, Tecator and similar devices, as they are designed to contain solid samples during the extraction process. This process involves a solvent flowing continuously through the sample, dissolving the soluble compounds.

Each cartridge, which takes a cylindrical shape, is made of a porous material such as cellulose or filter paper, allowing the solvent to pass through without mixing the solid particles. This ensures that only soluble compounds are extracted, keeping the solid samples contained within the cartridge.

In conclusion, the features of the extraction cartridge are:

– It provides compact containment for the solid sample.
– It allows solvent flow without entrainment of solid material.
– It ensures efficient separation between the extracted compounds and the residual solid, thus improving the efficiency of the extractor.

This component is essential for a clean and effective extraction process. Each cartridge has a capacity suitable for small samples. It makes them ideal for analysis in situations where efficient and fast extraction of compounds is sought, especially in laboratory studies requiring optimised use of resources or working with valuable or difficult to obtain materials.

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.

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?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.

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.
