            一般描述
            Visiprep™ Solid Phase Extraction Vacuum Manifolds andaccessories automate the preparation and cleanup of laboratory liquid samplesby solid phase extraction. Used with a vacuum pump, a Visiprep™ manifold canextract up to 12 or up to 24 samples simultaneously, significantly increasingsample throughput while decreasing sample preparation hands-on time, relativeto liquid-liquid extraction methods. Visiprep™ vacuum manifolds feature avacuum bleed valve and a stand-alone coverto provide you with precise flow control and safe, easy use.With our flow control valves you can precisely manipulate flow through eachtube by rotating the individual screw-valves built into the cover. Our recentlyoptimized standard manifolds are suitable for SPE methods in the PFAS testingarea. All crucial components that contain PFAS (e.g. PTFE) are substituted byPFAS free alternatives like e.g ultra-high molecular weight Polyethylene (UHMWPE) or stainless steel (needle guides). These ensure low PFAS backgroundcontamination during the SPE process. The glass basin will not dissolve, fog,or discolor when exposed to powerful solvents. The manifold rack accommodatesautosampler or small scintillation vials, 10 mm or 16 mm test tubes, or 1, 2, 5or 10 mL volumetric flasks. An optional plate fits up to ten 20 mLscintillation vials in the 12-port model. The vacuum bleed valve improves control of the vacuum level andensures more secure closure of the valve. This screw-type valve is fitted withan ultra-high molecular weight polyethylene cone shaped seal (now PTFE-free).Tightening the screw ensures a complete seal with no leakage at the valve.Loosening the screw breaks the seal, allowing immediate vacuum release to stopextractions or to lift the manifold cover. Four 2" legs enable you tostand the cover on a work surface with the SPE tubes maintaining their uprightpositions. This prevents solvent guides from resting on the work surface andbecoming damaged or contaminated. Drying attachment on themanifold is sold separately, it installs in minutes and can be used with anyinert gas. The drying attachment also is useful for concentrating recoveredsamples. Gas flow to each tube can be independently adjusted.


            應(yīng)用

            • 1.pH-sensitive pullulan-doxorubicin nanoparticles loaded with 1,1,2-trichlorotrifluoroethane as a novel synergist for high intensity focused ultrasound mediated tumor ablation: This innovative approach employs 1,1,2-Trichlorotrifluoroethane in nanoparticle formulations to enhance the efficacy of tumor treatments through high intensity focused ultrasound, showcasing its potential in pharmaceutical applications (Li et al., 2019).

            • 2.Chemical analysis and risk assessment of diethyl phthalate in alcoholic beverages with special regard to unrecorded alcohol: Although primarily focused on diethyl phthalate, this study highlights the broader scope of solvent safety in pharmaceuticals, suggesting indirect implications for handling and safety assessments of solvents like 1,1,2-Trichlorotrifluoroethane (Leitz et al., 2009).

            • 3.Quantitative determination of n-propane, iso-butane, and n-butane by headspace GC-MS in intoxications by inhalation of lighter fluid: This research demonstrates the use of advanced analytical techniques for volatile substances, which could be analogous to methodologies applied in studying environmental and safety aspects of 1,1,2-Trichlorotrifluoroethane in industrial settings (Bouche et al., 2002).


            特點(diǎn)和優(yōu)勢(shì)
            1.Patented screw-type valves within each SPE port for precise flowcontrol
            2.Glass basin will not dissolve, fog, or discolor when exposed tosolvents
            3.Legs on cover allow user to easily rest cover on work surface whenremoved from the manifold
            4.Screw-type solvent-resistant vacuum bleed gauge and valve offerbetter sealing and vacuum control. Valve takes 1/4″ vacuumtubing.
            5.PP collection vessel rack accommodates autosampler vials; smallscintillation vials (22.75 mm O.D. recommended); 10 and 16 mm test tubes; and 1, 2, 5, and 10 mL volumetric flasks. An optional plate for 20 mL scintillationvials is available for 12-port models.

                        （當(dāng)處理大體積樣品時(shí)，大容量采樣器可將樣品自動(dòng)加入到小柱中）
             57272                大容量采樣管 3管/套，用于12ml,20ml,60ml固相萃取小柱（功能同57275）
             57059                固相萃取連接管（聚四氟乙烯）100支/包 （防交叉污染傳輸線）
             57120-U  1000Ml            固相萃取緩沖瓶，塑料聚丙烯 （連接在固相萃取裝置和真空泵之間，
                        防止廢液吸到真空泵里而損壞真空泵， 初次購(gòu)買(mǎi)固相萃取裝置時(shí)須購(gòu)買(mǎi)）
             57020-U  SPE            轉(zhuǎn)接頭（小柱適配器）12只/包 （需要將2種小柱串聯(lián)起來(lái)，或者將小柱
                                    和儲(chǔ)液器、注射器等連接時(shí)使用）
            57146-U 流速調(diào)節(jié)閥螺母，24只/包（裝置上已包含，后期可購(gòu)買(mǎi)更換）
