描述

一般說明

Visiprep^™固相萃取真空装置和配件，通过固相萃取法自动化实验室液体样品的制备和净化。搭配真空泵，Visiprep™装置可同时萃取12至24个样品，相较液液萃取法极大地提高了样品通量，同时缩短样品制备的手动时间。Visiprep^™真空装置配备真空泄放阀和独立顶盖，带来精确的流量控制和安全性，使用方便。借助流速控制阀，你可通过旋转盖子上安装的独立螺旋阀，精准调节每支小柱的流量。我们的装置经过最新的标准优化，适合用于PFAS检测领域的固相萃取。所有含PFAS的关键组件（如，PTFE）都改用不含PFAS的替代品，例如超高分子量聚乙烯(UHMWPE)或不锈钢（导管），确保固相萃取的低PFAS背景污染。玻璃槽接触刺激溶剂后，不会溶解、模糊或变色。支架可容纳自动样品瓶或闪烁瓶、10 mm/16 mm试管、1/2/5/10 mL容量瓶。12位规格可选配能容纳10个20 mL闪烁瓶的支撑板。 真空泄放阀提高真空调节水平，确保阀门更紧密封闭。这种螺旋式阀配备超高分子量聚乙烯锥形密封（现已不含PTFE）。拧紧后可保证阀门完全密封无渗漏。拧松后破开密封，可立即释放真空停止萃取或升起顶盖。4个2”支脚用于将顶盖竖放在台面上，保持SPE小柱竖立。可以防止溶剂导管接触台面，受损或污染。 顶部安装的干燥装置单独售卖，可在数分钟内完成安装，可搭配任意惰性气体。干燥装置也可用于浓缩回收的样品。它到各小柱的气流可独立调节。

應用

• 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).


• 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).


• 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).

特點和優勢

• 每个SPE端口都配备专利所有的螺旋式调节阀，可精确控制流速
• 玻璃槽接触溶剂后，不会溶解、模糊或变色
• 顶盖带有支脚，当使用者从固相萃取装置上取下后，可方便地放在工作台上
• 螺旋式耐溶剂真空泄放表和阀门提供更好的密封和真空控制。阀门可与1/4″真空管相连。
• PP收集容器支架可容纳自动样品瓶、小闪烁瓶（推荐22.75 mm O.D.）、10和16 mm试管、1/2/5/10 mL容量瓶。可为12端口的型号选配用于20mL闪烁样品瓶的板。
