This time-tested, durable system provides one of the least expensive prices per position of all our N-EVAPs. The evaporative system, along with the standard flow control and pressure reducing regulator, enables the operator to achieve the desired level of concentration with efficient nitrogen usage. Our unique dual band spring hoist assembly ensures easy and effective operator use.Additionally, the 34 position N-EVAP includes a side control box, which provides timed and digitally controlled water bath temperatures to produce even evaporation rates. The pressure regulator and timer combine to allow timed automatic gas flow cut off which slows evaporation to a minimum once the timed cycle has been completed. In order to prevent damage to delicate samples, the timer also provides the option for the heat to shut off once the cycle is complete. N-EVAP nitrogen evaporators combine nitrogen blow down with a heated bath to gently concentrate delicate samples 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 * Nitrogen filter * Adjustable flow meter, 0-30 lpm * Built-in pressure reducing regulator * Side control box * Digital temperature controller * Electronic timer * Safety control cover plate * High pressure phthalate free tubing * High temperature limit switch for safety * Dual band spring hoist assembly * Precision needle valve tube assembly * Needles, 4-inch x 19 gauge with brass plated hub and stainless-steel shaft #### OPTIONS (Add to main Cat# when purchasing) * 220v wiring harness (Option Code# -2), Cat# 11634-2 * Z-Purge/positive pressure purge case (Option Code# -Z), Cat# 11634-Z * Acid resistant coating on instrument and needles (Option Code# -RT), Cat# 11634-RT * Reduced height (Option Code# -S), Cat# 11634-S Instrumental Name 34 Position N-EVAP Instrumental Catalog Number Number of Sample Positions Standard Dimensions (w x d x h) 24 x 19 x 34 in61 x 48 x 86 cm 19 x 17 x 32 in48 x 43 x 81 cm Reduced Height Dimensions (w x d x h) 24 x 19 x 24 in61 x 48 x 61 cm 19 x 17 x 24 in48 x 43 x 61 cm Sample Holder Layout Gas Manifold Layout Single Ring Test Tube Range (Standard Sample Holder) 10-30 mm OD Gas Flow Meter 0-30 L/min Stainless Steel Needles (Length x Gauge) 4.0 in x 19 ga102 mm x 19 ga Built-in Nitrogen Gauge Input 30-110 psig Sample Tray Lift Mechanism Dual Band Spring Hoist Assembly Rotating, Leak Tight Gas Fitting Acid Resistant Coating Heating Device Specs Model Number Heating Medium Inside Dimensions (Diameter x Depth) 16.0 x 4.5in40.6 x 11.4 cm Outside Dimensions (w x d x h) 24 x 19 x 6 in61 x 48 x 15 cm Total Wattage Bath Temperature Range Temperature Controller Type Digital Electronic with LED Display Controller Accuracy Side Mounted Control Box with Timer for Nitrogen & Heat #### TESTIMONIALS Catalog Number *All “-O” models come with a base and stand assembly instead of a heated bath.
