Why choose this product

Precision Filtration from USA

Whatman 934-AH filters are manufactured to exacting standards, ensuring consistent performance for critical laboratory tasks. Unlike generic alternatives, these filters are sourced from authorized US retailers, guaranteeing authenticity and adherence to strict quality controls. This means reliable particle retention and flow rates, essential for accurate scientific data in Indian research and quality control settings. Trust in a brand with a legacy of providing dependable filtration solutions.

Ideal for Specific Lab Work

These filters are best suited for applications requiring high particle retention and flow, such as total suspended solids testing, turbidity measurement, and bacterial culture filtration. They are also effective for cell harvesting and air pollution monitoring. However, if your work involves highly aggressive organic solvents that might degrade glass microfiber, or if you require sterile filters for sensitive cell culture media, consider specialized membrane filters.

How to use

  • Prepare the Filter — Ensure the 90mm Whatman 934-AH filter is correctly seated in your filtration apparatus. For critical applications, pre-wetting the filter with a compatible solvent may be necessary to ensure optimal performance and remove any residual manufacturing dust.
  • Apply Sample — Carefully pour or apply your sample (e.g., water sample for TSS, bacterial culture broth) onto the center of the filter. Avoid overloading the filter surface to maintain efficient flow and prevent premature clogging.
  • Complete Filtration — Apply vacuum or pressure as per your apparatus specifications to draw the sample through the filter. Monitor the filtration process for consistent flow. Once filtration is complete, dispose of the used filter according to laboratory protocols.

FAQ, See What Others Asked

How do I choose the right lab filter for my application?
Select filters based on your sample type and analysis goal. For water analysis, suspended solids, and bacterial cultures, Whatman 934-AH glass microfiber filters offer excellent retention and flow. For sterile filtration or specific solvent compatibility, consider membrane filters with appropriate pore sizes and materials.
What are the benefits of Whatman 934-AH glass microfiber filters?
These filters provide high particle retention, excellent flow rates, and high loading capacity due to their binder-free glass microfiber construction. They are suitable for a wide range of lab applications including water analysis and bacterial filtration.
Can I use these filters for sterile filtration?
While effective for many lab tasks, these glass microfiber filters are not typically used for sterile filtration of media or solutions requiring absolute microbial removal. For sterility, consider filters with a 0.22 micron pore size and appropriate membrane material.
What is the pore size of Whatman 934-AH filters?
The pore size is not explicitly stated as a micron value but is designed for high particle retention, suitable for applications like total suspended solids and turbidity removal. The 0.5psi wet burst pressure and specific air flow rate indicate fine filtration capabilities.
Are these filters suitable for organic solvents?
Glass microfiber filters are generally best for aqueous solutions and buffers. For aggressive organic solvents, it is recommended to use filters made from materials like PTFE to avoid potential degradation or sample adsorption.
How to buy authentic Whatman 934-AH filters in India?
Purchase from authorized US retailers and authorized brand partners like CrowCrowCrow. We import directly, ensuring factory-sealed products with all customs duties and GST included. Your order is shipped via ExpressBox tracked delivery to your Indian pincode.
