Whatman Cellulose Thimbles

Standard Cellulose Extraction Thimbles

Thimbles of type 603 are made from high-quality cellulose. For all automated extraction apparatus in common use, Whatman offers thimbles whose dimensions are matched exactly to those of the thimble holders to guarantee perfect fit. These thimbles can be used to a maximum temperature of 120°C.

Thimble size selection guide

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 millimeters. 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 to 2mm clearance, and be 5 to 10mm above the level of the top of the siphon tube.

Cytiva's Whatman cellulose thimbles are manufactured from high-quality alpha cellulose cotton linter for high-performance use in automated Soxhlet extractor systems. Their key features include:

A wide variety of solid-liquid extraction studies, including lipid and pesticide analyses in food and soil samples
Suitable for temperatures up to 120°C (248°F)
Excellent mechanical strength and retention
Wall thickness of standard thimbles is 1–1.5 mm to support application need
Option for double thickness for added rigidity

Soxhlet extraction for lipid analysis

Food samples can be prepared for lipid analysis using Soxhlet extraction.
Extraction thimbles are widely used for Soxhlet techniques. After extraction, samples can be refiltered with a 0.45 μm filter to remove small particles in order to protect your analytical instrument.
