Details
Advantec extraction thimbles are high purity, seamless filters with a characteristic thimble shape. Thimble filters are useful for a variety of analytic procedures:
- No. 84 - Cellulose Thimbles: Suitable for Soxhlet type extractions or dust sampling. Lipid content <0.1% by weight.
- No. 86R - Glass Fiber Thimbles: Made of strong borosilicate glass fibers, resistant to high temperatures 500 °C and most acids.
- No. 88R, 88H - Silica Fiber Thimbles: Made of quartz fibers, resistant to temperatures up to 1000 °C. Tapered for easy stack sampler loading.
- No. 89, 89S - PTFE and PTFE/Silica Fiber Thimbles: Durable, temperature-resistant thimble with minimal trace metals.
