Leverage Your MS Vacuum to Significantly Speed Up Separations

for Agilent GCs with 5971/5972, 5973, 5975, or 5977 GC-MS  

General purpose columns for FAMEs, flavor compounds, essential oils, solvents, xylene isomers, and US EPA Method 603 (acrolein/acrylonitrile). Resistant to oxidative damage. Temperature range: 40°C to 260°C. Equivalent to USP G14, G15, G16, G20, and G39 phases. The polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns.

Solutions for LC-ICP-MS

Innovative solution that enables investigation of multiple critical attributes for LNP drug products, without extensive sample preparation or dye requirements.

A tool for chromatographic purification of LNPs as an alternative to filtration methods.

One single kit to quickly and reliably determine 18 different and clinically relevant steroids with only one extraction process.

Sterivex-GP Pressure Sterile Filter Unit.

Steripak-GP filter units are designed for larger scale pressure-driven filtration of tissue culture media with or without serum. They are single use and are not autoclavable. The filter units come in two sizes, with the smaller unit able to filter up to 10 L and the larger up to 20 L. Both sizes utilize the low protein binding, fast flow 0.22 µm EMD Millipore Express membrane.

Steritop bottle top filter units provide a large filter area for rapid sterile filtration of aqueous fluids into narrow-mouth (33 mm) or wide-mouth (45 mm) bottles. A small tab inside the funnel secures an optional prefilter in-place during filtration. For added protection against contamination, the threads for bottle attachment have been slightly recessed in case the funnel accidentally touches a work surface

33 mm diameter sterile syringe filters.
