These quartz discs are manufactured by fusing naturally occurring crystalline silica.

Supplier: ENTEGRIS

These cartridge filters have superior retention efficiency with rapid particle removal and microbubble control which facilitates faster bath startup and system qualification.

Supplier: ENTEGRIS

These cartridge filters are designed for the removal of particles and microorganisms from liquids and gases. Used in clarification and prefiltration applications, these pleated filters retain contaminants primarily on the surface of the filter media. Downstream filter performance is enhanced due to efficient particle and microorganism reduction.

S-Pak™ hydrophilic sterile membranes are protected with a blue sheet of paper that keeps the membrane encountering with the film by ensuring maximum productivity and efficiency. This protective sheet prevents the migration of any adhesive.

Supplier: ENTEGRIS

These cartridge filters are widely used in chemical, electronic and semiconductor industries for liquid and gas prefiltration applications. They retain contaminants by means of a multi-stage, graded density design.

Supplier: Trajan Scientific and Medical

ZPure™ O₂/H₂O gas filters removes oxygen and water from inert gases, He, Ar, N₂ and H₂, making it ideal for use with GC and GC/MS carrier gas lines. It differs from the Zpure dual filter in that it is completely non-hazardous and is recommended for any application requiring ultra-pure gas, free from oxygen and water.

Supplier: Avantor Fluid Handling

Conveniently collect all filtered particles within the bag.

The ZPure™ H₂O/HC filter removes moisture and hydrocarbons from dry air or inert gases. The co-free moisture indicator signals breakthrough when it changes from green to blue.

Supplier: Avantor

Placed immediately before the column, the precolumn filter traps particles introduced with the sample. For samples, which may irreversibly absorb onto the column, the use of guard cartridges is strongly recommended.

Supplier: Trajan Scientific and Medical

The SPure H₂O/HC Filter removes moisture, oil, dust, and hydrocarbons (C5 and heavier) from dry air and inert gases.

Whatman Grade 4 Qualitative Filter Papers are a standard grade, high flow rate filter paper. They are useful in qualitative analytical separations when fast flow is required and the collection of fine particles is not critical.

Supplier: ENTEGRIS

These cartridge filters are designed with all fluoropolymer construction to consistently remove particles from a wide range of acids, bases and other process chemicals.

Supplier: ENTEGRIS

Wafergard® SG FG series gas filters provide superior particulate filtration to maximise photovoltaic cell and display manufacturing production yields.

Supplier: ENTEGRIS

Microgard UPE/UPX filters do not require prewetting with solvent-based photochemicals. All PE construction lowers metallic and ionic contamination that can leach from filters that are manufactured with materials such as PP and nylon.
