The SP Genevac miVac 2 range is designed to be modular and capable of removing water and organic solvents from a variety of sample formats including tubes, microplates and vials. Applications range from DNA, RNA and peptides, oligosynthesis and clinical diagnostics testing through to molecular biology.
Centrifugal evaporators remove solvent under vacuum: as system pressure drops, the boiling point of the solvent drops with it, so solvents can be removed at very low temperatures. Vapour boiling off the samples is either trapped in a condenser or pumped away. Samples are spun throughout, and the g-force generated is enough to keep each sample in its own tube rather than boiling over.
Choose your concentrator
- miVac 2 DNA — an integrated system supplied complete with a built-in high performance vacuum pump, concentration chamber and a fixed-angle aluminium rotor with 48 positions for 1.5 or 2 ml microcentrifuge tubes. Designed specifically for working with nucleic acids, it suits simple organic solvents such as methanol and ethanol up to 100 °C boiling point, and water in low sample numbers and volumes.
- miVac 2 Duo — accepts a two-swing position microplate rotor or Jet rotors for tubes.
- miVac 2 Quattro — a larger chamber taking a four-swing position microplate rotor and much higher capacity Jet rotors.
Both the Duo and Quattro control the pump, heat and run time, with specialised programs for water, alcohols and other solvents. Setting up uses a single ‘set and select’ control knob and a minimum of keys, with all status and program information on a large LCD display.
Choose your pump
- miVac 2 Duo Pump — a quiet, compact two-head diaphragm pump suitable for removing solvents that boil below 160 °C, including water, methanol, ethanol and their mixtures.
- miVac 2 Quattro Pump — a diaphragm pump reaching 3 mbar, required for successful drying of medium boiling point solvents.
- Super Vacuum Pump — a scroll-type pump for exceptionally demanding uses and freeze-drying, capable of routinely removing higher-boiling solvents at pressures down to 0.15 mbar.
All pumps are controlled automatically by the concentrator. When using solvent mixtures, a wide range of solvents, or a high vacuum pump, the miVac 2 Pressure Controller is recommended: it gives full control over running pressure, and a vacuum ramping mode starts concentration gently to help prevent bumping or spitting.
SpeedTrap — a high power cold trap
The cold condenser coils are suspended in the vapour path, so solvent vapours condense directly onto the coils and run off into the collection vessel below. The user can see the solvents in the trap at a glance and emptying is easy; the redesigned jar ensures safe removal and replacement. Three settings are available:
- Automatic defrost — the system periodically defrosts for a few minutes without interrupting the concentration process, preventing ice build-up. Ideal for solvents liable to freeze.
- Continuous chilling — for most organic solvents, giving the highest recovery. Ideal for solvents that do not freeze above -50 °C.
- Manual defrost — used after continuous chilling with solvents that freeze above -50 °C, for example when freeze-drying.
Rotors and freeze-drying
miVac 2 evaporators are the only ones in their class supplied with rotors made from solid aluminium. Speed increases compared with polypropylene types range between 40% and 200% depending on sample format, because the solid aluminium conducts heat energy to the samples where an open or plastic rotor effectively insulates them. A miVac Duo holds six shallow plates and the larger Quattro up to twenty shallow-well or eight deep-well plates.
The SpeedTrap with a Super Vacuum Pump may be used to freeze-dry up to 250 ml of water or other suitable solvents, or as a stand-alone freeze dryer by fitting the freeze-drying accessory jar in place of the regular collection vessel. Manufacturer’s note: the Duo Pump and Quattro Pump are not suitable for freeze-drying.

SP Genevac miVac 2 in Thailand
The SP Genevac miVac 2 is a modular centrifugal vacuum concentrator supplied and supported in Thailand by Thai Unique, built to dry samples held in tubes, microplates and vials by lowering pressure so solvents leave at gentle temperatures.

Where the centrifugal vacuum concentrator is used in Thailand
Based on the specifications above, the miVac 2 range suits laboratories that:
- Need to take water or organic solvents off DNA, RNA, peptide, oligosynthesis, clinical diagnostics and molecular biology samples without heating them hard, since dropping the pressure also drops the solvent’s boiling point.
- Work with a fixed sample format such as 1.5 or 2 ml microcentrifuge tubes, where the DNA model’s built-in pump, chamber and 48-position fixed-angle rotor cover the job as a single unit.
- Want to move between tubes and microplates as projects change, using the Duo’s two-swing plate rotor and Jet rotors, or stepping up to the Quattro’s larger chamber, four-swing plate rotor and higher-capacity Jet rotors.
- Need the pump matched to the chemistry — a two-head diaphragm pump for solvents boiling below 160 °C, a diaphragm pump down to 3 mbar for medium boiling points, or a scroll pump reaching 0.15 mbar for freeze-drying and higher-boiling work.

Frequently asked questions
Which miVac 2 model and pump should we choose if we dry both microcentrifuge tubes and microplates?
The DNA model is built around tubes and simple solvents such as methanol and ethanol boiling up to 100 °C, while the Duo and Quattro accept microplate rotors as well as Jet rotors and control pump, heat and run time with programs for water, alcohols and other solvents. If you run solvent mixtures or a high vacuum pump, the pressure controller, which can start with a stepped pressure reduction (vacuum ramping) to stop samples bumping, is worth discussing with our team.
Why buy SP Genevac miVac 2 from Thai Unique rather than direct from the manufacturer?
Because the people who look after it are here. Installation, calibration, scheduled maintenance, repairs with genuine parts and operator training are all handled by our team in Thailand, without routing every request overseas.
Can we test our own samples before deciding?
Yes. Our sample testing and method verification service runs your real samples so you can see the results this centrifugal vacuum concentrator gives on your workload before you buy.
How much does it cost, and how do we request a quotation?
Pricing depends on the configuration, accessories and the scope of work in your laboratory. Tell our sales team what you need to analyse and how many samples you run per day, and we will propose a configuration together with lead time and service terms.
