Filtration

Filtration equipment is essential for separating solids from liquids or gases in a variety of laboratory settings. This category encompasses a wide range of tools, from simple filter paper and funnels to sophisticated vacuum filtration systems and membrane filters. Filtration equipment works by passing a mixture through a porous material, trapping the solid particles while allowing the liquid or gas to pass through. This process is crucial for purifying solvents, preparing samples for analysis, and clarifying solutions. Workflows supported by filtration equipment include sample preparation for techniques like spectroscopy, chromatography, and microscopy, as well as general laboratory tasks like media sterilization and buffer preparation. Common applications of filtration equipment span diverse scientific fields, such as... + More

Filtration equipment is essential for separating solids from liquids or gases in a variety of laboratory settings. This category encompasses a wide range of tools, from simple filter paper and funnels to sophisticated vacuum filtration systems and membrane filters. Filtration equipment works by passing a mixture through a porous material, trapping the solid particles while allowing the liquid or gas to pass through. This process is crucial for purifying solvents, preparing samples for analysis, and clarifying solutions. Workflows supported by filtration equipment include sample preparation for techniques like spectroscopy, chromatography, and microscopy, as well as general laboratory tasks like media sterilization and buffer preparation. Common applications of filtration equipment span diverse scientific fields, such as pharmaceutical research, environmental monitoring, and food and beverage testing. For instance, researchers might employ syringe filters from brands like Sartorius or Millipore for sample preparation prior to HPLC analysis, while a microbiology lab might utilize vacuum filtration manifolds and Whatman filter paper for microbial enumeration. Similarly, in chemistry labs, Buchner funnels and filter flasks are commonly used for separating precipitates. Choosing the appropriate filtration equipment depends on factors like the particle size to be removed, the volume of the sample, and the chemical compatibility of the materials. Leading manufacturers of filtration equipment include Thermo Fisher Scientific, Agilent Technologies, and Mettler Toledo, offering a wide range of options to meet diverse laboratory needs. ALT offers a selection of pre-owned and refurbished lab filtration equipment, each backed by a standard 90-day warranty that can be upgraded to a three-year warranty, along with ALT's lifetime support. Because they're refurbished, lab filtration equipment from ALT are typically priced 50%-80% lower than the cost of new instruments, helping labs stretch their budget further without compromising on quality. - Less
