Max Pres Separation Filters

Max Pres Separation Filters are specialized filtration devices that separate biological sample components by size, making them useful for preparing cleaner, more consistent specimens. During filtration, pressure drives the sample through a porous membrane or filter medium; particles larger than the available openings are retained, while smaller particles and liquid pass through. This size-based separation can support sample clarification, particle enrichment, and preparation for downstream microscopy, analysis, or experimentation. By reducing unwanted material and improving sample uniformity, Max Pres Separation Filters help researchers process biological samples efficiently and obtain more reliable results.

Evaluating the Effect of Coated Filters and Pre-Filters on the Infectivity and Concentration of Aerosolized Phi6 Virus

0 Views •

2026

Here, we present a study to evaluate the anti-viral efficacy of copper- and silver-based surface coatings on air filters. Using a bioaerosol chamber and Phi6 bacteriophage, this method quantifies viral inactivation and mechanical filtration efficiency for self-sanitizing indoor air technologies.

Passive Filters

2024

Passive filters are utilized to shape the frequency spectrum of signals across a diverse array of applications. These filters, using only passive elements like resistors (R), inductors (L), and capacitors (C), are capable of selectively allowing or blocking certain frequency ranges without the need for external power sources. Low-Pass Filters Low-pass filters are designed to transmit signals with frequencies lower than the cutoff frequency, ωc, and attenuate those above it. The cutoff frequency...

The laser heated diamond anvil cell combined with synchrotron micro-diffraction techniques allows researchers to explore the nature and properties of new phases of matter at extreme pressure and temperature (PT) conditions. Heterogeneous samples can be characterized in situ under high pressure by 2D mapping and combined powder, single-crystal and multigrain diffraction approaches.

Pharmacodynamic Models: Emax Drug–Concentration Effect Model

0 Views •

2026

The Emax drug-concentration effect model is central to pharmacodynamics in drug discovery and development. This model is predicated on the receptor occupancy theory, which posits that the effect of a drug is directly related to the number of receptors occupied by the drug and the resultant complex formation.The model describes the reversible interaction between a drug (C) and a receptor (R) to form a drug-receptor complex (RC). The kinetics of this interaction are quantified by an equation that...
