About Extraction Thimbles - Size and Membrane Selection



Thimble sizes should be selected carefully to fit extractors correctly. The different sizes represent the established practice of showing the internal diameter and overall length of the thimble in millimetres. Therefore, an extra allowance for wall thickness should be made when calculating external diameters. The thimble should pass through the narrower end of the upper extractor socket, allowing 1-2 mm clearance, and be 5-10 mm above the level of the top of the siphon tube.




Thimble  Media Selection:
  
Cellulose
  
Thimbles made of high grade cotton cellulose. Smooth interior surface. Absolutely seamless. Fit most Soxhlet extraction devices
  
Fat determination of meat and diary products
Determination of PCB in fish products

Determination of free fats in food products

Determination of pesticide residues in food products

Extraction of plasticizers from PVC

Determination of organic compounds in washing agents

Extraction of additives from livestock feed

Extraction of dioxins

Solid particle such as dust collection in air flows

Evaluation of liquid content in concrete slurry
      
Glass Microfiber
  
High purity glass microfiber thimbles used for high temperature filtration, up to 550°C (1022°F), or when using solvents incompatible with cellulose thimbles.

Gravimetric methods for hot environments

Gravimetric methods for acidic gasses

Extraction methods common to biochemical analysis
