This instrument contains 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 a toggle switch for every row of 8 samples, which allows individual rows to be shut off when evaporating batches of less than 80 samples. Nitrogen gas flow is also controlled by an adjustable flow meter and a built-in pressure regulator. The 80 position MULTIVAP small vial evaporator 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. Sample blocks are customized, within a range of 10-17 mm, for the user’s sample size for maximum and even heat transfer. Since the heat block is made-to-order, we will request that you deliver us three sample vials for each unique vial size upon placing an order for a 30, 48 or 80 Position MULTIVAP. In situations where shipping sample vials to Organomation is not possible, we need precise measurements of your sample vials to be taken. All models can withstand contact with organic solvents; however acid resistant models are also available for use with corrosive solutions. Evaporate batches of up to 80 samples at once, with outside diameters of up to 17 mm Digital controls allow exact temperature regulation Cost-Effective Conserve gas by using ON/OFF valve for rows not in use Consistent Uniform evaporation across all samples with no adjustment needed between runs #### STANDARD FEATURES * Adjustable flow meter, 0-25 lpm * Dual band hoist spring assembly * High temperature limit switch for safety * Safety control cover plate * Digital temperature controller * Electronic timer * Nitrogen filter * Gas distribution manifold * Built-in pressure reducing regulator * Needle guide #### OPTIONS (Add to main Cat# when purchasing) * 220v wiring harness (Option Code# -2), Cat# 11880-2 * Z-Purge/positive pressure purge case (Option Code# -Z), Cat# 11880-Z * Acid resistant coating on instrument and needles (Option Code# -RT), Cat# 11880-RT * Pasteur pipette adapters in place of needles (Option Code -P), Cat# 11880-P * Manifold and stand only: no heating platform (Option Code -O), Cat# 11880-O Instrumental Name 80 Position MULTIVAP Heater Type Instrumental Catalog Number Number of Sample Positions Overall Dimension (w x d x h) 16 x 14 x 30 in41 x 36 x 76 cm 13 x 15 x 26 in 33 x 38 x 66 cm 13 x 15 x 26 in 33 x 38 x 66 cm Sample Holder Layout Rectangular Gas Manifold Layout 8 x 10 Array Center to Center Spacing Between Positions 0.8 in2.03 cm 0.8 in 2.03 cm Test Tube Diameter 10-17 mm OD Gas Flow Control On/Off Valve Every row of 8 Stainless Steel Needles(Length & Gauge) 4.0 in x 19 ga102 mm x 19 ga 4.0 in x 19 ga 102 mm x 19 ga 4.0 in x 19 ga 102 mm x 19 ga Needle Guide Hoist Assembly Dual Pulley & Band Springs Integrated Control Box with Timer for Nitrogen & Heat Built-in Gas Regulator Input 30-110 psig Acid Resistant Coating (Option Code -RT) OA-SYS Heating Device Specifications Model Number Outside Dimensions 16 x 14 x 6.5 in41 x 36 x 15 cm Total Wattage Temperature Range Temperature Controller Type Digital Electronic with LED Display Controller Accuracy #### TESTIMONIALS * What is Nitrogen Blowdown Evaporation * MULTIVAP Instruction Manual (Catalog #s 11809, 11830, 11848, 11880) - Version 22.5 * MULTIVAP Parts and Accessories List * 80 Position MULTIVAP Brochure and Specifications #### ACCESSORIES * Custom sized inserts (cat# NA1881, cat# NA1882) * Pasteur pipette adapters (cat# NA0636, cannot be used with needle guide) * Luer plugs (cat# NA1307) * Pressure reducing regulator 0-160 psi (cat# NA0630) * Various needle sizes and gauges #### GET A QUOTE ------------------------------------------------------------ ABOUT THIS CONTENT ------------------------------------------------------------ Source: https://www.organomation.com/products/nitrogen-evaporators/multivap/80-position Author: Organomation This content is provided for informational purposes.
