Visiprep 5位烧瓶真空固相萃取装置 57101-U

Visiprep 5 位烧瓶真空固相萃取装置

The Visiprep 5-Port Flask Vacuum Manifold enables analysts using Supelco solid phase extraction tubes to simultaneously prepare up to 5 samples. Unlike conventional vacuum manifolds, the Visiprep 5-Port Flask Manifold allows users to collect their SPE eluate directly into 50 mL round or flat bottom flasks for direct Rotovap evaporation. The manifold consists of a chemical resistant 5-port cover (DL or standard available), gasket, base, a glass basin, vacuum gauge and bleed valve, 5 flow control valves, 5 replaceable solvent guide needles, and a base plate that supports up to five 50 mL round or flat bottom flasks.
Each port on both the standard and DL Visiprep models are equipped with flow control valves.
Recommended Flasks: Aldrich single-neck flask, 50 mL, joint: ST/NS 24/40
Round Bottom (Cat. No. Z414484)
Flat Bottom (Cat. No. Z418773)
与标准 Visiprep 型号不同，Visiprep DL（一次性连接管）型有效消除了在同一端口连续萃取样品时发生交叉污染的可能。这种经济的 PTFE 一次性连接管插入各 DL 固相萃取装置的端口，通过溶剂导向器直接进入收集容器（50mL 烧瓶）。由于从固相萃取柱出来的试剂和样品只能与一次性连接管的内表面接触，从而消除了在同一端口处理多个固相萃取样品时发生交叉污染的风险。
