General description

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)

與標準 Visiprep 型號不同，Visiprep DL（一次性連接管）型有效消除了在同一端口連續(xù)萃取樣品時發(fā)生交叉污染的可能。這種經(jīng)濟的 PTFE 一次性連接管插入各 DL 固相萃取裝置的端口，通過溶劑導向器直接進入收集容器（50mL 燒瓶）。由于從固相萃取柱出來的試劑和樣品只能與一次性連接管的內(nèi)表面接觸，從而消除了在同一端口處理多個固相萃取樣品時發(fā)生交叉污染的風險。
