These point-of-use filters meet small to mid-volume photochemical filtration needs for positive developer and DI water applications. Both Optimizer® DEV filters (for developer applications) and Optimizer® DI filters (for DI water applications) require no pre-wetting, so the filters function immediately after installation. The design also limits the handling of hazardous chemicals during the installation and promotes a healthier workplace. Do not use either filter with aromatic hydrocarbons.

Supplier: Restek

Ultra C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape. It is made of high-purity, type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications.

Supplier: Restek

These Viva columns are based on a wide pore material designed for optimal large-molecule separations. Base-deactivated spherical silica is useful for normal-phase or HILIC separations. These columns have a narrow distribution around the mean pore size, permitting a larger portion of the silica surface to play a role in the separation.

Supplier: Restek

Viva C8 columns are conventional monomeric octylsilane columns offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. These general-purpose C8 columns are suitable for a wide range of compounds from acidic through slightly basic.
