In addition to the FlashPure series filled with silica, C18, as well as amino and diol stationary phases, we have newly started selling Pure+Flash. Furthermore, our PrepPure columns for preparative HPLC and SFC feature unique selectivity for polar and non-polar, chiral and achiral compounds, with chemically bonded silica, as well as a lineup of coated or immobilized polysaccharides. 【Product Lineup】 ■ Cartridge columns for flash chromatography ・Pure+Flash ・FlashPure ■ Columns for preparative HPLC and SFC ・General-purpose columns ・Chiral separation columns *For more details, please download the PDF or feel free to contact us.

The "Pure C-900" is an entry-level preparative chromatography model suitable for first-time flash chromatography. The connected devices are automatically recognized due to its modular design, allowing for flexible combinations of peripheral equipment based on application and budget. The time required for preparative purification is about 1/5 that of using an open column, saving both effort and time. Would you like to significantly improve the efficiency of your preparative purification? 【Features】 ■ Easy connection ■ Convenient pre-packed cartridges ■ Reduces consumption and exposure to organic solvents ■ Increased speed and reproducibility with pump-driven liquid delivery and two-solvent gradient elution ■ Powerful pump with a maximum flow rate of 300 mL/min and pressure resistance of 50 bar (5 MPa) ■ UV (254, 275, 325, 365 nm fixed four wavelengths) trigger detects peak elution and automatically collects fractions *For more details, please download the PDF or feel free to contact us.

The Pure series is a space-saving, smartly designed preparative chromatography system. Some models are equipped with an ELSD that does not miss peaks even with samples that have no UV absorption. Standard features include mobile phase residual, waste liquid, and solvent leak sensors. *Excluding C-805. The operation is simple, allowing for separation condition settings, control, and monitoring on a single screen. Parameters can be changed even during preparative purification. 【Features】 ■ Space-saving design ■ By using a solvent container stand, the mobile phase can be positioned at the top of the device ■ High safety ■ The fraction collector's door and ventilation system prevent exposure to solvent vapors ■ Simple operability *For more details, please download the PDF or feel free to contact us.

The "Sepiatec SFC" is an integrated unit that can be installed in the same space as an evaporator (SFC-50). Designed with ease of use in mind, it features an intuitive operation that is suitable for all users. There are various models and options to choose from based on your intended use, and it is equipped with all the necessary functions for a fractionating SFC in an all-in-one package. 【Features】 ■ Expertise from specialists ■ Large-scale injections in a short time ■ Simple yet smart setup ■ Minimal lab footprint ■ All-in-one *For more details, please refer to the PDF materials or feel free to contact us.

Related Device: Fractionation Chromatography System Pure C-815 Cholesterol and its esters, which are components of biological membranes, are utilized as industrial raw materials in cosmetics, pharmaceuticals, and liquid crystals. When performing gradient fractionation purification for compounds that are difficult to detect with UV detectors, methods are selected using low wavelength UV detection such as 210 nm or ELSD (Evaporative Light Scattering Detector). ELSD is a fractionation purification method that overcomes the disadvantages of UV-triggered fractionation due to the absence of baseline drift and T0 peaks. By adopting ELSD & UV double triggering, it enables complementary fractionation purification using both ELSD and UV. 【Issues with Low Wavelength UV Triggered Fractionation】 ■ The baseline drifts due to the solvent's own absorption used in the mobile phase, making it difficult to detect sample peaks. ■ Baseline rises consistently during gradient steps, leading to the baseline being recognized as a peak, which significantly increases purification time and fraction volume. *For more details, please refer to the PDF document or feel free to contact us.

Easy operation! Does your sample contain compounds without UV absorption? Equipped with both a UV detector and ELSD, it performs fractionation by triggering both simultaneously. Additionally, it can handle higher flow rates and pressures than conventional models (up to 30 MPa). From crude purification to full-scale high-pressure fractionation, purification can be performed with easy operation. 【Features】 ■ SLIM & SAFETY ■ Ensures safety with a closed fraction collection section ■ Built-in UV detector and ELSD ■ Capable of handling high flow rates and pressures ■ Purification can be performed with easy operation *For more details, please refer to the PDF materials or feel free to contact us.
