Rocket Evaporator

Rocket evaporatorConcentration and evaporation is an important step in achieving accurate analytical results with sample extracts. It is also labor intensive. The Rocket Evaporator automates this process, allowing the analyst to spend more time on other projects.

The Rocket Evaporator can be used either to dry samples completely, or to concentrate them to a small volume. It is equipped with the advanced performance features that Dionex users expect, such as effective bumping and cross-contamination protection, precise temperature regulation, and easy-to-use controls. A two-stage cold trap is built into the Rocket Evaporator, providing high levels of solvent recovery, even with volatile organic solvents. The cold trap auto-drains under the control of the evaporator to ensure that optimal solvent recovery is maintained, no matter what mix of solvents is being used.

Rocket evaporator parts

To help achieve the best results in the desired sample format, there are several options:

1. Evaporation Flasks:
450 mL volume For drying or concentrating samples. When drying, samples must be re-dissolved then removed via pipette.

2. SampleGenie™ Flasks:
250 mL (plus vial) For vials from 12 mm to 28 mm diameter and up to 70 mm in height. The SampleGenie system allows drying of the sample directly into the storage vial.

3. SampleGenie for GC Vials
Specifically for concentrating into GC autosampler vials, this special version of SampleGenie insulates the vial so that only the solvent in the flask evaporates, leaving a small volume in the vial.

4. Pucks for ASE® Tubes
The Puck insert replaces the flasks and allows up to 18 ASE tubes to be evaporated at one time.

5. Flip-Flop system
Samples are collected directly from the extraction system in the special double-ended tube. A SampleGenie adaptor with GC vial is then fitted. The tube is flipped over and placed into the Puck in the Rocket Evaporator and the cap removed. The samples are then concentrated directly into the GC vial.

Recirculating Chiller

A powerful, compact recirculating chiller is available with the Rocket evaporation system, which is specified to complement the evaporator. The evaporation system can be connected to the chiller by RS232 link, enabling the evaporator to control the chiller, which can provide improved solvent recovery and better drying of samples than by using a static cooled supply. A connection kit with insulated pipe work is available for this chiller.
