Product Overview
Whatman Grade TCLP Glass Microfibre Filters are engineered for demanding laboratory applications requiring high chemical resistance and thermal stability. These binder-free filters are composed of 100% borosilicate glass microfibres, ensuring minimal extractables and consistent performance in aggressive solvent environments. The TCLP grade is specifically designed for Toxicity Characteristic Leaching Procedure testing, meeting EPA Method 1311 requirements for hazardous waste analysis. Their uniform pore structure provides efficient particle retention while maintaining fast flow rates, reducing filtration time without compromising accuracy. The filters exhibit exceptional durability under extreme pH conditions (1-14) and can withstand temperatures up to 500?C, making them suitable for gravimetric analysis and high-temperature applications. Their smooth surface minimizes particle shedding, while the consistent thickness ensures reproducible results across multiple samples. The glass microfibre composition eliminates organic binders that could interfere with analytical results, particularly in trace metal analysis. These filters are compatible with most common laboratory filtration apparatus and can be used with both aqueous and organic solvents. Their high loading capacity reduces the need for frequent filter changes during sample processing. The TCLP grade filters are manufactured under strict quality control to ensure batch-to-batch consistency, with each filter undergoing rigorous testing for weight, thickness, and particle retention efficiency.
FAQs
1. What makes TCLP grade filters different from standard glass microfibre filters?
The TCLP grade is specifically designed for Toxicity Characteristic Leaching Procedure testing, offering higher chemical resistance and lower extractables compared to standard glass microfibre filters. They meet EPA Method 1311 requirements for hazardous waste analysis.
2. Can these filters be used with organic solvents?
Yes, Whatman TCLP glass microfibre filters are compatible with both aqueous and organic solvents due to their borosilicate glass composition and lack of organic binders.
3. What is the maximum temperature these filters can withstand?
These filters can withstand continuous operation at temperatures up to 500?C, making them suitable for high-temperature applications and gravimetric analysis.
4. Are these filters suitable for trace metal analysis?
The binder-free composition and low extractable content make these filters particularly suitable for trace metal analysis where organic contamination must be minimized.
5. How should these filters be stored to maintain their performance?
Store the filters in their original packaging in a clean, dry environment away from direct sunlight and chemical vapors. Avoid handling with bare hands to prevent contamination from skin oils.
