12 Position N-EVAP Nitrogen Evaporator

Organomation

 

Compact unit that allows for up to 12 samples to be evaporated simultaneously.

  • Precise gas flow control at each sample position via precision needle valve. Ideal for the simultaneous evaporation of samples with varying evaporation end points.
  • Sample tray has a spring tensioner allowing ANY test tubes ranging from 10-30 mm to be processed without any instrument modification.
  • Optional small sample holder allows samples with an outside diameter of 5-16 mm to be processed.

12 position N-EVAP

Heated water bath or dry bath model available

The 12 position N-EVAP was the first nitrogen evaporator created by Organomation.  It has proven to be an extremely durable, time tested and highly affordable member of Organomation’s N-EVAP line. These economical units provide controlled concentration of sample vials through the application of nitrogen gas within a heated water bath. The N-EVAP’s circular rotating design permits each sample to be accessible from the front of the instrument for easy insertion and retrieval. The chrome plated needle valves are individually milled from solid brass, enabling precise, uniform adjustments for your nitrogen blow down. This promotes efficient and safe sample reduction with minimal nitrogen waste.

Advantages:

  • Small Footprint: N-EVAP Model# 111 has the smallest footprint of all the N-EVAPs
  • Flexible:  A small sample holder option can be added to accommodate vials with a smaller outside diameter in the range of 5-16 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:

  • Nitrogen filter
  • Adjustable flow meter, 0-10 lpm
  • High pressure phthalate free tubing for safety, Teflon tubing for no contamination
  • High temperature limit switch for safety
  • Dual band spring hoist assembly (except in dry bath model)
  • Precision needle valve tube assembly
  • Needles, 4 inch x 19 gauge with chrome plated brass hub and stainless steel shaft

Optional Features (contact us for more info and pricing): 

  • Z-Purge/intrinsically safe purge case 
  • Acid resistant coating on instrument and needles

Highlighted Application:

EPA 415.3Determination of Total Organic Carbon and Specific UV Absorbance at 254 nm in Source Water and Drinking Water

This method provides procedures for the determination of total organic carbon (TOC), dissolved organic carbon (DOC), and UV absorption at 254 nm (UVA) in source waters and drinking waters. The DOC and UVA determinations are used in the calculation of the Specific UV Absorbance (SUVA). For TOC and DOC analysis, the sample is acidified and the inorganic carbon (IC) is removed prior to analysis for organic carbon (OC) content using a TOC instrument system. In this method, the N-EVAP laboratory evaporator is used as a sparging device. The stainless steel needles of the N2 Evaporator are lowered into the 40- mL sample vials containing the TOC or DOC samples to remove inorganic carbon by sparging with nitrogen gas.

Other N-EVAP Applications:

• EPA Method 539

• EPA Method 548.1

• EPA Method 523.1
