New Solvent Removal for Kilo Scale Preparative Chromatography
Genevac’s Rocket 4D Synergy evaporator offers automatic and improved drying or concentration
10 Jun 2018
The Rocket 4D Synergy evaporator from Genevac is designed to provide a productive tool for automatic drying or concentration of very large volumes. Configured with a 5-litre 316 stainless steel evaporation vessel – the Rocket Synergy 4D offers productive automated removal of solvent for labs running kilo scale preparative chromatography equipment.
Traditionally such labs have relied upon using several rotary evaporators to remove the large volumes of solvent from sample fractions. This time consuming manual process requires a dedicated operator to top-up dry ice in cold traps, feed the systems with more product and watch the systems continually. With a Rocket 4D Synergy evaporator you simply load your sample, select a method, press start, and walk away – the system will do the rest.
Compact in size the Rocket 4D Synergy allows you to dry or concentrate your samples with complete confidence as it uses proprietary vacuum technology to suppress solvent bumping and foaming – problems associated with sample loss when using large scale rotary evaporators.
Users wishing to dry volumes larger than five litres require the ‘Autofeed’ option, which enables the Rocket 4D Synergy to automatically draw in further chromatographic eluent ready for evaporation. The Rocket 4D Synergy controls product feed, drying and the discharge of condensed waste solvent without any external intervention. The autofeed system has an integrated rinse circuit which enables dried products to be automatically re-dissolved in a small volume of solvent at the end of the process.
Alternatively, the same circuit can be used under manual control for solvent exchange, by selecting a different solvent for re-dissolve. Cleaning the Rocket 4D Synergy between cycles is very straightforward. The PTFE feed tubing is easily detached for cleaning or replacement and the vessel can be readily cleaned, wiped, inspected and even put in a dishwasher. The Rocket 4D Synergy also includes powerful cold traps that maximise solvent recovery protecting the environment and improving drying of samples.

Rocket 4D Synergy Large Volume Evaporator
GenevacRocket 4D Synergy is designed primarily to evaporate large sample volumes, with autofeed if required, allowing automatic evaporation of volumes up to 100 litres. Rocket 4D Synergy provides fast, safe evaporation for solvents with a boiling point of up to 165°C (DMF) and can easily dry aqueous samples. The system feeds the solution for evaporation to the evaporation vessel, controls temperature and 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. 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.
