#### DESCRIPTION

The 9 position MULTIVAP is a high temperature dry block model designed to evaporate large volume samples. The benchtop evaporator 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. An unheated version is available for evaporations that will be performed at ambient temperatures. 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. 

**Capacity**

Evaporate large volume samples of up to 100 mL each

**Precise**

Digital controls allow exact temperature regulation

**Wide Temperature Range**

High temperature heat block can be programmed up to 120 °C for hard-to-evaporate solvents
