FAQs of GVWP04700 MEMBRANE FILTER PAPER:
Q: How is the GVWP04700 Membrane Filter Paper used in laboratory filtration?
A: The GVWP04700 membrane filter is typically placed in filtration apparatus to separate particles and microorganisms from liquid samples. Its 0.22 m pore size allows efficient retention of very small contaminants, making it ideal for critical analytical procedures such as water quality testing and environmental monitoring.
Q: What are the benefits of using a sterile and autoclavable membrane filter?
A: Sterile filters prevent contamination of sensitive samples, while autoclavable construction allows reuse after sterilization. This ensures both safety and reliability for laboratory work, helping maintain sample integrity during repeated use.
Q: When should I select this filter paper over other types?
A: Choose the GVWP04700 membrane filter when you require high retention efficiency for very small particles or microorganisms, especially in applications like microbiological analysis, water quality testing, or clinical sample filtration.
Q: Where can lot number traceability be useful?
A: Lot number traceability is essential for quality control and auditing. Laboratories can track the specific batch used for experiments and comply with regulatory requirements, improving accountability and reproducibility of results.
Q: What is the process for autoclaving this membrane filter paper?
A: Before use, the membrane filter paper can be autoclaved in standard laboratory autoclaves due to its high mechanical strength and structure. Simply place the filter in a suitable container and follow your facilitys autoclaving protocol for sterilization.
Q: How does the hydrophilic and low protein binding feature enhance performance?
A: The hydrophilic nature allows for rapid sample passage and uniform filtration, while low protein binding minimizes sample loss by preventing proteins from adhering to the membrane, ensuring accurate analysis results.
Q: Is the GVWP04700 Membrane Filter Paper customizable to other sizes or specifications?
A: No, the GVWP04700 is not customizable and is supplied as a 47 mm diameter, round disc filter with the specified properties.
