    Answer: Whatman 1004-027 Quantitative Filter Paper is primarily used for qualitative analysis in laboratories, especially in applications requiring reliable particle retention and filtration. Its 20-25 micron pore size allows it to effectively filter fine particulate matter from liquids, making it ideal for tasks ranging from sample preparation to clarification of solutions. This grade of filter paper is perfect for laboratory use in fields such as chemistry, environmental testing, and biological research.
  • Question: What is the flow rate of the Whatman 1004-027 filter paper?

    Answer: The flow rate of the Whatman 1004-027 filter paper is 3.7 s/100 mL/sq inch. This means that the filter can process a specific volume of liquid efficiently within a set time frame. A higher flow rate allows for quicker filtration processes, making it suitable for laboratories that need to analyze multiple samples promptly without compromising on quality.
  • Question: What diameter do the Whatman 1004-027 filter circles have?

    Answer: The Whatman 1004-027 filter circles have a diameter of 27 mm. This compact size allows for easy use with various types of apparatus in lab settings, such as funnel setups, ensuring a tight fit and preventing sample loss. The small diameter is especially advantageous for filtering small samples efficiently, making it a go-to choice in analytical labs.
  • Question: What are the benefits of using Grade 4 filter paper?

    Answer: Grade 4 filter paper is designed for applications requiring moderate retention while still allowing for efficient filtration. Its capabilities make it a popular choice in various laboratory settings. The paper is suitable for use with general filtration tasks where speed is essential but retaining a reasonable amount of material is also necessary, like in enzyme assays or groundwater analysis.
  • Question: How many filter circles are included in a pack of Whatman 1004-027?

    Answer: Each pack of Whatman 1004-027 contains 400 filter circles. This bulk packaging is beneficial for laboratories that require a high volume of filters for routine testing and experiments. Purchasing in bulk can reduce the frequency of reordering, allowing lab technicians to focus on their work without interruptions.
  • Question: Can the Whatman 1004-027 filter paper be reused?

    Answer: Reusing Whatman 1004-027 filter paper is not recommended due to the potential for contamination and loss of structural integrity during the filtration process.

  • Question: Is the Whatman 1004-027 filter paper acid resistant?

    Answer: Yes, Whatman 1004-027 filter paper has moderate acid resistance, making it suitable for filtering acidic solutions in various labs. However, for highly aggressive chemicals, it is advisable to test compatibility. This characteristic is particularly beneficial when working with samples in fields such as environmental science or chemical analysis, where acidic materials are common.
  • Question: How should Whatman 1004-027 filter paper be stored?

    Answer: Whatman 1004-027 filter paper should be stored in a cool, dry place, ideally within its original packaging to prevent contamination and damage. Keeping filters in a moisture-free environment helps maintain their integrity and filtering capabilities. Proper storage extends the usability of the filters, which is crucial for maintaining consistent handling in laboratory settings.
  • Question: What applications can the Whatman 1004-027 filter paper be used in?

    Answer: The Whatman 1004-027 filter paper is versatile and can be used in various applications such as qualitative analysis, liquid-phase separations, and even in educational laboratories for demonstrations. Its ability to efficiently filter samples without altering their chemical properties makes it ideal for experiments in biology, environmental monitoring, and food safety testing.
