12 Position N-EVAP
Nitrogen Evaporator

#11155

The 12 position N-EVAP nitrogen evaporator (cat# 11155) is a compact unit that allows for up to 12 samples to be evaporated simultaneously. At each individual sample position, the gas flow can be controlled via a precision needle valve. This is ideal for the simultaneous evaporation of samples with varying evaporation end points. The sample tray has a spring tensioner which allows any test tube between 10-30 mm to be processed without any modifications to the instrument. An optional small sample holder allows samples with an outside diameter of 5-16 mm to be processed.

First introduced in 1959 as The Meyer N-EVAP, the 12 position N-EVAP (cat# 11155) was the first nitrogen dryer 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.

24 Position N-EVAP
Nitrogen Evaporator

#11250

The 24 position N-EVAP is our most adaptable benchtop evaporator. The basic model offers all of the standard features from our N-EVAP line. Additionally, the 24 position N-EVAP offers the most customizable options for your sample preparation needs. The standard sample holder can accommodate samples with an outside diameter of 10-30 mm. However, with the optional 8 position large sample holder, vials with an outside diameter of 30-70 mm can be processed. The 24 position N-EVAP test tube evaporator can also be upgraded to include digital controls for heat and time with the addition of the side control box (Option code -CB).

These economical units provide controlled concentration of sample vials through the application of nitrogen gas within a heated water bath. The dual band spring hoist assembly provides a simple and effective means of removing samples from the 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. Time tested technology and proven construction ensure a long lasting, user-friendly experience.

64 Position MULTIVAP
Nitrogen Evaporator

#11364

The 64 position MULTIVAP nitrogen blowdown evaporator is a water bath model. 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 64 samples. Nitrogen gas flow is also controlled by an adjustable flow meter and a built-in pressure regulator.

The 64 position MULTIVAP parallel evaporator uses a heated water bath to reach evaporative temperatures ranging from 30°C to 100°C. An unheated version is available for evaporations that will be performed at ambient temperatures. Sample racks are customized within a range of 11-30 mm for the user’s sample size. Please specify sample size (outside diameter and length to nearest 0.1 mm) when placing an order. All models can withstand contact with organic solvents; however acid resistant models are also available for use with corrosive solutions.
