Electronic Grade Precision Filter Element

Electronic grade precision filter element mainly used in chemical, gas, water, CMP slurries and photoresist Semiconductor industry include integrated circuits, data storage, flat panel displays, and photovoltaics.

Each filter type from a wide selection of materials rates highly on product characteristics and adheres to strict quality control programs.

Electronic grade precision filter element belong to membrane filter cartridge, PULLNER has produced filters constructed of PTFE, Polyarylsulfone, nylon, PVDF, polyethylene, and polysulfone, providing the best selection for each application.

It is specifically designed to limit iron extraction so that it meets the requirements of chemicals and organic solvents in the electronics industry.

Ultrapure chemicals are the foundation of semiconductor manufacturing. These specialty chemicals range from acids, bases, and alcohols to solvents and ketones, which require a wide range of filters with varying chemical compatibility.

PULLNER utilizes state-of-the-art manufacturing equipment to manufacture and assemble in a controlled environment electronic-grade chemical filters that are ultra-clean and produce low levels of extractable and metal ions.

Every electronic grade chemical filter is 100% integrity tested. Excellent chemical compatibility is suitable for the filtration of various wet etching solutions and the filter cleaning (WEC) process of wet etching strippers.

High retention particle retention efficiency up to 99.99%. Available in a wide range of pore sizes from 0.02um to 10um in a wide range of pore sizes to meet different requirements.

Can be used for hydrophilic PTFE membranes While PTFE membranes are inherently hydrophobic, Electronic grade precision filter element is made of hydrophilic membranes and does not require pre-wetting.

Each element is independently tested for integrity.
