Вопросы и ответы клиентов

  • вопрос: What is the material composition of Whatman 1004-090 Quantitative Filter Paper?

    отвечать: The Whatman 1004-090 Quantitative Filter Paper is made from high-quality cellulose fibers. This composition ensures high purity and reliability, ideal for analytical filtration tasks. The cellulose offers excellent retention of fine particles, making it suitable for applications such as gravimetric analysis and laboratory use. Therefore, if you're performing experiments that require precise particle separation, this filter paper is specifically designed to deliver the desired results.
  • вопрос: What are the key specifications of the Whatman 1004-090 Filter Paper Circles?

    отвечать: The Whatman 1004-090 Filter Paper Circles feature a diameter of 90mm, a pore size of 20-25 microns, and a flow rate of 3.7 seconds per 100mL per square inch. These specifications lead to effective filtration and clarity in results. Ideal for quantitative analysis in laboratories, the Grade 4 filter paper efficiently retains fine solids while allowing liquid to pass through rapidly. This balance makes it especially practical for sample preparation in research applications.
  • вопрос: What types of applications are suitable for using the Whatman 1004-090 Filter Paper?

    отвечать: The Whatman 1004-090 Filter Paper is widely used in various applications such as laboratory experiments, environmental testing, and food and beverage analysis. Its reliable performance in retaining fine particulates makes it an excellent choice for quantitative analysis where precision is critical. For instance, in a chemistry lab, researchers frequently utilize this filter paper for gravimetric determinations to ensure accurate results each time.
  • вопрос: How should the Whatman 1004-090 Filter Paper be stored?

    отвечать: To maintain the integrity of the Whatman 1004-090 Filter Paper, it should be stored in a cool, dry place away from direct sunlight and humidity. Keeping it in its original packaging until ready for use will safeguard against contamination and damage. Proper storage ensures consistent performance when you depend on these filters for critical laboratory experiments, ensuring reliable results time and again.
  • вопрос: Can the Whatman 1004-090 Filter Paper be used with aggressive solvents?

    отвечать: The Whatman 1004-090 Filter Paper is designed primarily for aqueous and mildly aggressive solutions. While it excels in filtering water-based samples, its cellulose composition may not withstand harsh organic solvents or aggressive chemicals. For users needing filtration for such solvents, it is recommended to consult the product specifications to select an appropriate filter paper that meets those specific requirements.
  • вопрос: What is the difference between Grade 4 and other grades of Whatman filter papers?

    отвечать: Grade 4 Whatman filter paper, including the 1004-090 model, has a moderate retention level compared to other grades. It offers excellent flow rates and is suitable for applications requiring significant sample volumes and moderate retention of particulates. In contrast, higher grades like Grade 1 and 2 are used for finer filtration and lower flow rates. Therefore, if rapid filtration with some retention capability is your goal, Grade 4 is an optimal choice.
  • вопрос: How do I determine the appropriate filter paper size for my application?

    отвечать: To determine the appropriate filter paper size, consider the volume of the liquid you need to filter and the vessel you are using. The Whatman 1004-090 Filter Paper, with its 90mm diameter, is suitable for medium-sized laboratory glassware. If you're working with smaller volumes, opting for a smaller diameter may provide more efficient filtering. Always choose a size that adequately fits your funnel or filtration apparatus to ensure optimal performance.
  • вопрос: Is the Whatman 1004-090 Filter Paper pre-washed?

    отвечать: Yes, the Whatman 1004-090 Filter Paper is pre-washed, reducing contamination risks in sensitive analytical applications. The pre-washing process eliminates any residual substances that may interfere with your results. This feature allows researchers to have complete confidence in their findings, particularly when conducting quantitative analyses or experiments that require high levels of accuracy in data.
  • вопрос: How do I use Whatman 1004-090 Filter Paper effectively in my experiments?

    отвечать: To use the Whatman 1004-090 Filter Paper effectively, first ensure that your equipment is clean and free from contaminants. Place the filter paper in the funnel, ensuring a secure fit, and slowly pour your sample to prevent overflow or splashing. Monitor the filtration process and be mindful of the flow rate, which is 3.7 seconds per 100mL. Following these steps will help you achieve optimal filtration and accurate results in your experiments.
