Universal needle filter

Universal needle filter is a commonly used filtering tool in laboratories, which can be used to filter various liquid samples, including water, organic solvents, acids, bases, alcohols, etc., and is almost suitable for all solutions. This type of filter is usually composed of a filter membrane made of special materials, which can effectively remove pollutants such as particles, bacteria, viruses, etc. from the sample.

To avoid high costs and inconvenience caused by preparing various filters. Multi purpose filters can be used for aqueous and corrosive organic solvent solutions.

Low protein binding film, high recovery rate of key protein samples.

Accurate analysis. HPLC certification shows low levels of UV extractable substances.

Using a fiberglass pre filter version makes it easy to filter samples rich in particulate matter.

The 13mm Acrodisc needle filter with minispoke structure produces low retention and is easy to filter into the automatic injection bottle.

Compared to other filters, it can better avoid the accumulation of particulate matter in chromatography columns and instruments
