This 47mm in-line holder (Model IFH47) is available in both type 316 stainless steel. The PTFE coated support screen prevents the sticking of the membrane during autoclaving. The back-pressure support screen protects the filter from rupture during reverse pressure surges. Upstream vent enables venting at any time during filtration. The dual sealing system compresses filter to ensure no lateral wicking/leaking. The locking ring enables filter changes without disconnecting from lines. Unit comes standard with silicone o-ring and FPM vent o-ring. When filtering gases, it is recommended that a second support screen be used upstream of the membrane. Replacement parts and alternate o-ring materials are available.

Applications:

• Sterilize and ultraclean liquids and gases under positive pressure. Sterilize with membrane in place for microbiological studies.
• Install for point-of-use filtration on filling machines. General particulate analysis

Sample And Mobile Phase Filtration Are Simple, Economical Practices That Serve To Extend The Life Of Consumable HPLC Parts, Decrease System Wear And Tear, And Preserve The Integrity Of The HPLC System.

Serious Problems When Operating A HPLC System Can Be Avoided By Performing Routine Maintenance. Most HPLC Part Replacement Tasks, Such As Changing Pump Seals, Are Readily Recognized As Necessary Maintenance; However, Mobile Phase And Sample Filtration Are Also Maintenance Practices. Routine Sample And Mobile Phase Filtration Are Simple, Inexpensive, And Convenient Ways To Decrease HPLC Problems.

Regardless Of The Technical Intricacies And Cost Of The System Chosen, All HPLC Systems Have The Same Basic Components, Indicated In Figure 1.

vacuum filtration manifold complete kit is primarily used for simultaneously filtering multiple liquid samples, making it valuable in microbiology, analytical chemistry, and other fields. It enables efficient and consistent filtration by utilizing a vacuum pump to draw liquid through a series of filter holders, collecting solids while separating them from the liquid. Key applications and features:

• Microbiological analysis:Collecting bacteria or other microorganisms from liquid samples for testing. 
• Sterility testing:Ensuring the absence of microorganisms in pharmaceutical products or other materials. 
• Solvent purification:Separating impurities from solvents used in chemical reactions or other processes. 
• Water quality analysis:Assessing the presence of particulate matter in water samples. 
• Suspended solid analysis:Determining the amount of solid particles in a liquid suspension. 
• Simultaneous filtration:Processing multiple samples concurrently, saving time and increasing throughput. 
• Reduced cross-contamination:Each filter holder has its own valve, minimizing the risk of contamination between samples. 
• Efficient filtration:The vacuum system accelerates the filtration process compared to gravity filtration. 
• Various funnel and membrane options:Compatible with different funnel materials (glass, polypropylene, etc.) and membrane filter sizes (47mm, etc.). 
• Complete kits:Available with vacuum pumps, manifolds, filter holders, and other necessary components. In essence, a vacuum filtration manifold complete kit is a versatile tool for efficiently and reliably processing liquid samples, particularly when dealing with multiple samples or when rapid filtration is desired. 

Micro Filtration Funnel 100 ml are sterile plastic funnels. They allow quick performance of the filtrations required in the routine testing of water, food and beverages, pharmaceutical and cosmetic products. A gridded membrane is placed on a stainless steel filter support and a MFunnel is simply and practically fitted on. The sample is filtered. The funnel is made of polypropylene and thus is elastic enough for optimal sealing with a click-fit closure. Graduations are marked for sufficiently exact sample volumes. The large inner diameter ensures a high flow rate. The optimized shape allows a thorough rinsing of the system subsequent to filtration.Reliable results – use a new, sterile funnel for each test to avoid of cross contaminationTime-saving – just change the funnel, rather than spending time sanitising itSimple handling – no more holding of hot funnels

They have been designed specifically for applications in which the particles or microorganisms retained on the membrane filter surface are of interest. Simple handling is very important regarding routine examinations. Stainless steel taps in the base allow the vacuum to be turned on and off.

Aone Mobile phase filtration is a simple and economical way to extend the lifetime of HPLC instrument supplies. It reduces instrument downtimes and helps to maintain the precision of the HPLC system. The negative effects of improper filtration practices are often underestimated, and can impact almost every part of the flowpath. Most HPLC supplies maintain tasks such as replacing pump seals are considered mandatory procedures, but mobile phase and sample filtration are often forgotten. The use of Ultrapure prefiltered organic HPLC solvents renders the filtration process not required. However, using water-based buffer solutions, predominant with Biopharma applications, makes it mandatory to filter the mobile phases. Residue of undissolved salt crystals can lead to reduced pump seal lifetimes, and microbial growth can cause increased baselines and capillary and column clogging. Therefore, filtering mobile phase buffers should be done daily through a 0.2 µm filter, and should be considered a routine part of sample analysis.  solvent filtration assembly is manufactured from high-quality borosilicate glass components, and can hold a 47 mm membrane filter to remove particulates from liquid media

The first sidearm flask functions as the vacuum trap and the second acts as the overflow back-up. These two flasks contain enough household bleach so that the final concentration of waste is 10% bleach when full. An in-line PTFE 0.2um filter is the last defense and prevents aerosols from entering the line. The flasks should be set in a plastic bucket or tray so that if they break, the spill is easily contained. This image is adapted from the Biosafety in Microbiological and Biomedical Laboratories.

Buchner funnels are used in the laboratory for vacuum-assisted liquid filtering. In organic chemistry, these funnels are used to collect recrystallized compounds because they help remove moisture from the final product.

Buchner funnels consist of an open straight-sided cylindrical chamber that narrows to a tube- or pipe-shaped opening. The tube-like extension can be placed through a stopper, which is then placed into the top of a filtration or Buchner flask. Plastic versions may have a bung hole located at the side of the chamber to which a vacuum may be attached. Buchner funnels are reusable.

The bottom of the Buchner funnel chamber may be perforated or contain a separate fritted disc. Filter paper is used for Buchner funnels with perforated lower surfaces. Place the filter paper of the preferred porosity inside the chamber, pre-wet, add the liquid, and apply the vacuum.

Funnels with fritted glass discs do not require filter paper. The fritted glass will be porosity-rated as fine, coarse, medium, etc. Filtration with a Buchner funnel proceeds more quickly than letting the liquid flow simply using gravity. Most Buchner funnels are also rated for a maximum vacuum pressure.
