N-EVAP Automated Blowdown Evaporator, 20 Position, with wate (C003B-037441)

The Automatic 20 Position N-EVAP® is an advanced blowdown evaporator combining classic blowdown technology with timed automation. The unit can run in automatic or manual mode due to the integration of a unique pneumatic system. The automatic mode removes samples from the heating medium when the designated time cycle has been completed. Samples can also be removed manually 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. A 9 position automatic instrument is also available for large glassware with outside diameters of 30-54 mm. Advantages: Automation : Samples are raised out of the bath and the gas flow is shut-off after the timed endpoint has been reached Flexible : A 9 position large sample instrument can be chosen to accommodate vials with a larger outside diameter in the range of 30-54 mm Gentle : N-EVAP nitrogen evaporators combine nitrogen blow down with a heated bath to gently concentrate delicate samples Individualized Control : Gas flow can be controlled at each sample position via needle valves Standard Features: Adjustable flow meter, 0-20 L/min Adjustable pressure regulator, 0-30 psig High temperature limit switch for safety Digital temperature controller Electronic timer Precision variable valve technology Pressurized cylinder technology Precision needle valve tube assembly Needles, 4 inch x 19 gauge with plated brass hub and stainless steel shaft
