The MDRD Equation. The following is the IDMS-traceable MDRD Study equation (for creatinine methods calibrated to an IDMS reference method) GFR (mL/min/1.73 m 2) = 175 × (S cr) -1.154 × (Age) -0.203 × (0.742 if female) × (1.212 if African American) The equation does not require weight or height variables because the results are reported

For filters in sequence, one or both can be upgraded to achieve the MERV 13 level or higher. For example, two MERV 11 filters (each 65% efficient) in sequence would be 88% efficient, which better than a MERV 13 filter (for 1-3 um particles). Outdoor air is free of viral particles. HVAC filters that only filter outdoor air do not need to be

Dec 30, 2019 · When the spec sheet said, "Effective filtration area," it meant it. The filter took care of however many square feet of surface area the pool had. It filtered that area. Got it. The D.E. and sand filter spec sheets ruined my day. When the "effective filtration area" was 6 square feet, the filter processed 57,000 gallons of water in 8 hours.

HPLC certified for low levels of UV-absorbing extractables. Easy filtration of viscous, particulate-laden samples with glass fiber prefilter version. The Acrodisc Premium Syringe Filters are ideal for automated sampling or sample clarification with a larger EFA than typical 25mm devices. They offer two powerful features in one premium filter.

Acrodisc PSF Syringe Filters feature a large effective filtration area (3.9 cm 2) for increased sample throughput, ideal for sample volumes of ≤ 150 mL. Pall Acrodisc PSF Syringe Filters are designed to be fully compatible for use with automated robotic handling systems offering reliable and worry-free operation.

Effective Filtration Area Syringe filters are available in a range of sizes with different effective filtration areas (EFA). EFA is the filter area that is available for filtration. For a given membrane, the larger the filter area, the higher the flow rate and greater the throughput.

Polypropylene with white colorant. Filter media. Polypropylene or 300 series stainless steel. Effective filter area. 7.5 cm 2 / 1.16 in 2. Operating Conditions 2. Maximum allowable pressure. 2.1 barg / 30 psig @ 20 °C / 68 °F. Dimensions - Luer-Lok compatible variant.

Jun 25, 2020 · The objective of this study is to investigate the effect of plasma-based surface modifications on static charges of electrospun filter media and their resulting filtration performance. Polystyrene (PS) electrospun web (ES) had inherent static charges of ~3.7 kV due to its electric field-driven process, displaying effective filtration performance.
