It combines our classic N-EVAP benchtop evaporator with timed automation technology, and optional nitrogen self-generation. This unit can run in automatic or manual mode due to the integration of our unique pneumatic system. The automatic mode removes samples from the heating medium when the designated time cycle has been completed. You can also manually remove samples when the evaporation process is completed with the flip of a switch. The automatic concentration cycle reduces the likelihood of loss or damage to samples. A digital control system provides the operator with timed control of gas flow and bath temperature. Automation Samples are raised out of the bath and nitrogen flow is shut off after the timed endpoint has been reached An adjustable sample holder design fits a wide variety of sample tubes and vials at once Digital controls allow exact temperature regulation Individualized Control Optimize evaporation of diverse samples with individual gas flow control at each vial #### STANDARD FEATURES * Adjustable flow meter, 0-25 LPM * Built-in pressure reducing regulator * High pressure phthalate free tubing * High temperature limit switch for safety * Safety control cover * Digital temperature controller * Electronic timer * Dual nitrogen filters * Precision variable valve technology * Pressurized cylinder technology * Safety circuit breaker * Precision needle valve tube assembly * Set of 20 needles, 4-inch x 19 gauge with plated brass hub and stainless-steel shaft #### OPTIONS (Add to main Cat# when purchasing) * 220v wiring harness (Option Code# -2), Cat# 11220-A-2 * Z-Purge/positive pressure purge case (Option Code# -Z), Cat# 11220-A-Z * Acid resistant coating on instrument and needles (Option Code# -RT), Cat# 11220-A-RT Instrumental Name Automatic 20 Position N-EVAP Instrumental Catalog Number Number of Sample Positions Overall Dimension (w x d x h) 19 x 18 x 36 in49 x 46 x 92 cm Sample Holder Layout Gas Manifold Layout Single Ring Test Tube Range (Standard Sample Holder) 10-30mm OD Gas Flow Meter 0-25 L/min Stainless Steel Needles (Length & Gauge) 4.0 in x 19 ga102 mm x 19 ga Built-in Nitrogen Gauge Input 30-110 psig Sample Tray Lift Mechanism Gas Piston Rotating, Leak Tight Gas Fitting Built-in Control Box with Timer for Nitrogen & Heat Acid Resistant Coating (cat#-RT) Heating Device Specs Model Number Heating Medium Inside Dimensions (Diameter x Depth) 11 x 11 x 5.5 in49 x 46 x 14 cm Outside Dimensions (w x d x h) 19 x 18 x 7 in49 x 46 x 18 cm Total Wattage Bath Temperature Range Temperature Controller Type Digital Electronic with LED Display Controller Accuracy * What is Nitrogen Blowdown Evaporation * N-EVAP Instruction Manual (Catalog #s 11220) - Version 22.5 * N-EVAP Parts and Accessories List * Auto-20 Position N-EVAP Brochure and Specifications #### ACCESSORIES * Nitrogen generator (Cat# NA1955) * Pasteur pipette adapters (Cat# NA0636) * Pressure reducing regulator 0-160 psi (Cat# NA0630) * High temperature silicone fluid (Cat# NA1240) * Various needle sizes and gauges #### REPLACEMENT PARTS * NA1955: Generator, Nitrogen Gas, 20 L/min * NA0603: Needles 4in x 19ga, SStl 304 shaft, brass plated hub, dozen * NA0636: Pasteur pipet adapter, male luer to fluted nut, dozen #### GET A QUOTE ------------------------------------------------------------ ABOUT THIS CONTENT ------------------------------------------------------------ Source: https://www.organomation.com/products/nitrogen-evaporators/n-evap/20-position-auto Author: Organomation This content is provided for informational purposes.
