Extraction Thimbles
High purity, seamless filters with a characteristic thimble shape. Applications include analysis of fats, oils, grease, pesticides, pollutants, other organics and additives in plastics and rubber materials.Cellulose Thimbles – No. 84
• Suitable for Soxhlet extractions of organic components
• Dust sampling
• Lipid content <0.1% by weight
• Borosilicate glass
• High temperature extractions or dust monitoring (≤500°C)
• Acid resistant (except hydrofluoric)
Quartz Fiber Thimbles – No. 88R and 88RH
• Use up to 1,000°C
• No. 88RH is treated at 900°C to stabilize the weight prior to use
PTFE Fiber and PTFE/Quartz Fiber Thimbles – No. 89 and 89S
• Durable, temperature-resistant
• Non-adsorptive with respect to acid gases
• PTFE is inherently hydrophobic
• Little or no trace metal contamination
