Product Overview
Whatman Extraction Thimbles DT are engineered for precision in Soxhlet and solvent extraction applications, ensuring reliable sample preparation with minimal contamination. Constructed from high-purity cellulose, these thimbles provide exceptional particle retention while maintaining chemical compatibility with a wide range of solvents, including organic and aqueous solutions. The uniform porosity and robust structure prevent fiber shedding, guaranteeing consistent filtration performance even under prolonged extraction cycles. Their cylindrical design maximizes surface area for efficient solvent interaction, reducing extraction time without compromising yield. The thimbles are free from binders and additives, ensuring no interference with analytical results, making them ideal for quantitative analyses in research and quality control. Their thermal stability allows for autoclaving, while the inert nature of cellulose ensures no reaction with extracted compounds. Whether used in environmental testing, food analysis, or pharmaceutical research, these thimbles deliver reproducibility and accuracy, minimizing the need for repeat extractions. The variety of sizes accommodates diverse sample volumes, from small-scale experiments to larger batch processing, without sacrificing filtration efficiency. Their compatibility with standard Soxhlet apparatus ensures seamless integration into existing lab workflows, reducing setup time and operational complexity.
FAQs
1. What solvents are compatible with Whatman DT extraction thimbles?
These thimbles are compatible with most organic solvents like hexane, acetone, ethanol, and dichloromethane, as well as aqueous solutions. Always verify solvent compatibility with your specific extraction protocol.
2. Can these thimbles be reused after extraction?
Whatman DT thimbles are designed for single-use to prevent cross-contamination and ensure consistent performance. Reuse may compromise filtration efficiency and sample purity.
3. How do I select the right thimble size for my application?
Choose a size that accommodates your sample volume without overfilling. Larger thimbles (e.g., 43x123MM) suit bulkier samples, while smaller sizes (e.g., 16x60MM) are ideal for trace analysis or limited sample quantities.
4. Are these thimbles suitable for high-temperature extractions?
Yes, the pure cellulose construction withstands temperatures up to 120?C, making them suitable for most Soxhlet extraction conditions. Avoid direct flame exposure to prevent charring.
5. Do these thimbles require pre-treatment before use?
Pre-rinsing with the extraction solvent is recommended to remove any loose fibers and condition the thimble, ensuring accurate results in sensitive applications.
