What is Millipore membrane?

Millipore Express® PLUS polyethersulfone (PES) membrane filters are commonly used as an alternative to cellulose membranes and are known for their thermal stability, durability and resistance to acidic and alkaline solutions.

What does a Millipore filter do?

The Millipore Filter technique is a new method for the concentration, removal, and enumeration of bacteria in liquids and air. Its application to the evaluation of the sanitary condition of pipe lines cleaned in place is disaussed, together with other possible applications to water, milk, and food bacteriology.

What is membrane filter used for?

Membrane filters act as a barrier to separate contaminants from water, or they remove the particles contaminating the water. Reverse osmosis, ultrafiltration, and nanofiltration all use a membrane in their different filtration processes.

What is Seitz filtration?

[′zītz ‚fil·tər] (microbiology) A bacterial filter made of asbestos and used to sterilize solutions without the use of heat.

What is PTFE membrane?

PTFE membrane (Polytetrafluoroethylene) technology uses patented and proprietary processes to sinter then skive PTFE into rolled membrane materials that can then be converted into numerous other forms. Our controlled processes enable us to manufacture a unique porous PTFE membrane with unmatched properties.

What is durapore filter?

Durapore 0.1 µm polyvinylidene fluoride (PVDF) filters can be used for filtration of cell culture media and feeds. Durapore® 0.22 μm hydrophilic PVDF filters are suitable for sterile filtration of liquids.

What is Millipore value?

The Millipore value provides a measure to calculate the amount of dirt on the component or the complete engine. Therefore, OEMs decide on a Millipore value for their entire engine assembly. Based on their Millipore value, they provide these values for every engine component.

What is PTFE membrane used for?

PTFE filters are the versatile choice for size-selective samplers. The material’s unique properties make it ideal for gravimetric, chemical, and/or microscopic analysis of sample particulate. PTFE filters are used for aerosol sampling, air venting and gas filtration.

What does a 0.22 micron filter remove?

The 0.22-micron filter is one of the smallest used in patient care, and removes bacteria. There are not currently filters that remove viruses. Not all intravenous medications should be administered through a filter, and others may require filters of a specific size.

What are membrane filters?

Membrane filters, produced by precipitation or stretching of polymeric materials, are used for a variety of applications (e.g. filtration, air particle monitoring). Properties of membranes differ markedly based upon their composition, fabrication method, surface treatment, and pore size.

Why choose hydrophobic durapore® membranes?

Hydrophobic Durapore ® membranes exhibit high protein binding. Quartz fiber filters are manufactured from pure quartz fibers, preventing any surface filter reaction with acidic gases. Due to their inertness, quartz fiber filters are well suited for measuring heavy metal concentrations and small particle quantities.

What is a Millipore membrane used for?

Millipore ® polyvinylidene chloride (PVC) membranes, due to their low weight and low water adsorption, are preferentially used with gravimetric analysis to quantify silica, carbon black, or quartz air particulates.
