9 Position MULTIVAP Blowdown Evaporator for 100mL beakers, a (C08-0524-033)

The MULTIVAP® blowdown evaporator is ideal for concentrating large batches of samples, and can be used in numerous sample preparation methodologies. These instruments contain a rectangular gas distribution system mounted on a frame and dual post assembly. The manifold delivers nitrogen gas to the needles or glass pipettes, which direct the gas onto the sample’s surface. This method results in rapid solvent evaporation and sample concentration. In order to conserve nitrogen gas, the manifold has toggle switches which allow gas flow to individual rows to be shut off when evaporating batches at less than full capacity. The 9 position MULTIVAP (Catalog# 11809) is a high temperature dry block model designed to evaporate large volume samples. The instrument contains a rectangular gas distribution system mounted on a frame and dual post assembly, allowing the needles to be raised and lowered with ease. The manifold delivers nitrogen gas to the needles or glass pipettes, which direct the gas onto the sample’s surface. This method results in rapid solvent evaporation and sample concentration. In order to conserve nitrogen gas, the manifold has a toggle switch for every row of 3 samples, which allows the individual rows to be shut off when evaporating batches of less than 9 samples. Nitrogen gas flow is also controlled by an adjustable flow meter and a built in pressure regulator. The 9 position MULTIVAP uses a heated aluminum dry block to reach evaporative temperatures ranging from 30°C to 120°C. The sample block is built to fit beakers with an outside diameter of 50 mm, and 9 beakers are included with the instrument. If another sample size is to be used, inserts can be purchased and customized for your sample. Please specify sample size (outside diameter and length to nearest 0.1 mm) when placing an order for inserts. All models can withstand contact with organic solvents; however, acid resistant models are also available for use with corrosive solutions.
