Rocket Evaporators use patented vacuum technology to evaporate solutions to dryness, or a concentrate, rapidly and safely.
The latest Synergy series offers integrated, flexible solutions for processing a wide range of sample volumes. Interchangeable rotors will accommodate tubes, flasks and batch volumes of up to 100L.
Two models are offered:
Rocket Synergy, will evaporate samples in flasks, tubes, or a variety of innovative Genevac sample holders such as the SampleGenie. The removable rotor may be replaced with a 5L 316 stainless steel vessel for batch processing.
Rocket 4D Synergy is designed primarily to evaporate large sample volumes, with autofeed if required. The Rocket 4D Synergy can also be fitted with a removable flask rotor to accommodate the full range of Rocket Sample handling solutions such as flasks, tubes and SampleGenie.
Now you don't need to choose between flask or batch/feed evaporation. The Rocket and Rocket 4D Synergy evaporators will accommodate your process, whatever the volume. Each is capable of replacing several rotary evaporators and saving valuable bench space.
The Rocket Synergys rotor can be replaced with a vessel for batch processing.
The Rocket 4D Synergys vessel can easily be removed and replaced with a flask rotor.
There are two principle applications for the Rocket:
1. for concentrating to a small volume
2. for drying samples completely
The Rocket evaporator has been specifically designed with automated sample concentration in mind. Typically, samples require concentratation before analysis to enable more accurate results to be obtained, and is often used in the field of Environmental Analysis, for example, to determine if there are any pesticide residues in a vegetable crop.
The Rocket can concentrate up to 6 flasks of 450ml in parallel, and if desired, concentrate the samples directly into a 2ml GC autosampler vial, with no user intervention. The speed of evaporation previously not been available, and enables users to abandon highly labour intensive methods, and make time for science.
The key to this unique concentration capability is a fundamentally new drying technology developed by Genevac engineers. It uses steam at low temperatures (such as 40°C) and vacuum to dry the samples, with the result that the process is up to five times faster than other technologies capable of unsupervised operation. Crucially, the Rocket Evaporator is also equipped with the advanced performance features that Genevac users expect, such as effective bumping and crosscontamination protection, precise temperature regulation and very easy to use controls. A technical paper on Rocket technology
is also available.
There are two keys to accurate concentration with the Rocket, first is use of the SampleGenie flask for GC vials, and second is the correct concentration method.
flask enables a large volume of several hundred millilitres to be concentrated directly into a 2ml GC vial. To prevent concentration continuing once the sample is in the vial, the vial is insulated from the heat so that concentration stops. The Rocket evaporator detects this end point and then stops the concentration process automatically.
To enable this process to happen efficiently, it is imperitive to have the best concentration method. All of the methods on the Rocket Evaporator can be changed. The user can upload and download methods and date via a USB data key. Methods can be locked if desired, or some facets may be altered by the user.
An alternative method of achiving concentration would be add small qunaitiy of a less volatile solvent as a solvent "keep". This method has been used successfully with the Genevac EZ-2 Evaporator
and is detailed on our concentration technology
page. To save bench or fume hood space, the EZ-2 can be used on the robust Infinity Trolley .
The Rocket Evaporator has been designed to concentrate and dry samples in parallel, very fast. The Rocket can dry up to 6 flasks of 450ml, and if desired, concentrate the samples directly into small vials, all with no user intervention. The speed of evaporation previously not been available, and enables users to abandon highly labour intensive methods, and make time for science rather than attending to their evaporator.

Samples may be dried into a standard Genevac evaporation flask, where they will then need to be redissolved in a small volume of strong solvent and pipetted to the appropriate container for the next step in the process, or, can be dried directly into small storage vial of your choice, which eliminated the redissolving and transfer stages. This uses Genevac SampleGenie
The Rocket Evaporator is supplied with a set of preprogrammed methods which cover most solvents and their combinations, however, custom methods can be sent to users via e-mail and readily uploaded to the system via a USB data key. Stored evaporation data can also be downloaded from the system, or recorded directly on the USB key. To save bench or fume hood space, the EZ-2 can be used on the robust Infinity Trolley .
Each Puck can hold three ASE ®
vials, taking the total capacity of the Rocket Evaporator
to 18 vials. The Rocket dries these tubes very quickly and in parallel, providing complete safety for the sample. Dri-Pure ®
technology prevents bumping and cross contamination and the system has precise temperature control - not forgetting that your samples are cold while they are boiling. Rocket delivers very high analyte recoveries, even for the most volatile analytes.
To concentrate most samples in ASE ®
vials, it is necessary to add a solvent keep. More can be found about this methodology on the Concentration technology page
The maximum working volume of vials in the Puck is 55ml. Evaporation speeds in the Puck are fast - 33 minutes for 18 vials with 55ml of hexane, 55 minutes for 18 vials with 55ml of methanol. These at a typical low steam temperature of 40°C. The samples when boiling are typically between 0°C and -20°C depending on operating pressure.
Rocket 4D is an automated evaporation system for large volumes of solvent, from a few litres to 50 litres or 100 litres. The system feeds the solution for evaporation to the evaporation vessel, controls temperature, controls pressure, prevents bumping and foaming, drains the condenser, stops when dry or concentrated, and if required, redissolves the product in a small volume of solvent, unattended, and with no user intervention! Rocket 4D provides fast, safe evaporation for solvents with a boiling point of up to 165°C (DMF), and can easily dry aqueous samples.
