Microfiltration - Membrane Filters
Membrane filters are constructed out of a wide range of synthetic materials, including cellulose acetate, regenerated cellulose, mixed esters (cellulose nitrate), polyamide (nylon), polycarbonate, polypropylene, polyvinylidene, polyethersulfone and polytetrafluoroethylene (Teflon). Because of their small pore-diameter, membrane filters tend to have a slower flow rate than depth filters and they are called surface filters.

Chromatography - HPLC Columns
High-performance liquid chromatography (HPLC) is a technique in analytical chemistry used to separate, identify and quantify each component in a mixture. The sample mixture to be separated and tested is sent into a stream of solvent (mobile phase) to the column which contains the chromatographic packing material needed (stationary phase) to make the separation. The mixture moves through the column at different speeds and interacts with the stationary phase. The velocity of each component in the mixture depends on its chemical nature, the nature of the column and the composition of the mobile phase.

Chromatography - TLC Thin Layer Chromatoghraphy
TLC (Thin Layer Chromatography) is like all chromatographic techniques, based on a multistage distribution process. This process involves a suitable adsorbent (the stationary phase), solvents or solvent mixtures (the mobile phase), and the sample molecules. For Thin Layer Chromatography, the adsorbent is coated as a thin layer onto suitable support (e.g. glass, polyester or aluminium plate), on this layer the substance mixture is separated by elution with a suitable solvent. The most frequently used separation technique is ascending TLC in a glass chamber (standard method, linear development). Usually, it is applied as a single development. However multiple developments, with or without change of mobile phase can improve separation results.

Chromatography - SPE Columns
Solid-Phase Extraction (SPE) is a separation process by which compounds that are dissolved or suspended in a liquid mixture are separated from other compounds in the mixture according to their physical and chemical properties. Analytical laboratories use solid-phase extraction to concentrate and purify samples for analysis. Solid-phase extraction can be used to isolate analytics of interest from a wide variety of matrices, including urine, blood, water, beverages, soil and animal tissue. SPE is solvent consumption, convenient, safe and high efficiency. Our manufacturing process minimizes variability and improves recovery and clean-up procedures.
