DescriptionCentrifugal concentrators are capable of removing water and organic solvents from a variety of sample formats.
Accepts a swing rotor for microplates and also take disc rotors for tubes and vials. Choice of medium or high vacuum pumps and a dedicated DNA system with built-in pump. Simple to use, and allows safe concentration of samples or complete dryness. Time and temperature monitored on the large clear display. Parameters set using the set-and-select dial. To improve performance, built-in special modes work with water and alcohols, which optimize concentration time. miVac system controls heat and thus provides protection for your valuable samples. With a wide variety of available rotors, miVac evaporators are suited to many different tasks, including drying or concentration in microcentrifuge tubes, conical centrifuge or other plastic tubes, glass vials and shallow or deep well microplates. Their simple, robust design will ensure years of reliable service even when used intensively, such as in teaching or multi-user laboratories. The intuitive controls allow inexperienced users to get first class results the first time with most samples, while allowing more sophisticated programming for experienced workers. miVac concentrators are extremely quiet when in use and typical results with water show that miVac systems are faster than comparable machines. Performance can be further enhanced through the use of the miVac SpeedTrap refrigerated condenser.
MiVac DNA system
The miVac DNA integrated system is a centrifugal concentrator capable of removing water and organic solvents from a variety of sample formats and is designed specifically for working with nucleic acids. It is supplied with built in high performance vacuum pump, concentration chamber and a fixed angle aluminium rotor for 1.5mL microcentrifuge tubes. The miVac DNA is suitable for simple organic solvents, e.g. methanol, ethanol, up to 100°C BP, and water in low sample numbers. There is a range of possible rotors including an option for microtitre plates. For a wider range of solvents and/or a larger range of sample formats select miVac Duo or Quattro concentrator with miVac SpeedTrap and pump.
miVac Duo and Quattro concentrators
The miVac Duo system has been designed to accept a two-swing position microplate holder or disc rotors for tubes and vials. The miVac Quattro is a bigger system with a larger capacity bowl, enabling it to use a four swing position rotor and much higher capacity disc rotors. In both swing rotors, each position for shallow well microplates can accept multiple plates through the use of stackers. Both concentrators feature a simple user interface for setting and monitoring time, temperature and method.
miVac Duo and Quattro Vacuum Pumps
There is a choice of three pumps to complement the miVac concentrators according to your applications. The miVac Duo pump is a quiet and compact two-head diaphragm pump suitable for removing most solvents that boil below 130°C, including water, methanol, ethanol and their mixtures. For more demanding applications, such as higher boiling-point solvents up to 165°C, we recommend the miVac Quattro pump as this four head diaphragm pump can reach pressures of <2mbar which are needed for successful drying of medium boiling point solvents. Both pumps come in stylish housings to match the other miVac components and are controlled automatically by the miVac evaporation chamber. A scroll type vacuum pump is also available for high boiling point solvents. You should consult your local sales representative about the exact pump configuration for the application you have in mind.
The miVac SpeedTrap is a novel high power cold trap used to condense solvent vapors. Cold traps can seriously improve the performance of any vacuum concentration system. When a cold trap condenses vapors back to liquid, there is a corresponding massive volume reduction helping to pull a vacuum and speeding up the concentration process considerably.The miVac SpeedTrap operates in a unique way, the cold condenser coils are suspended directly in the vapor path, solvent vapors condense directly on to the coils and run off into the collection vessel below without freezing, even when using water. This method is highly efficient, with more than twice the condensing power of a similar system, the user can quickly see the solvents in the trap, and emptying the trap is easy requiring no defrosting. The collection vessel is removed with a simple quarter turn, allowing safe disposal of the solvents.
The miVac connection kit contains all that is needed to turn the separate units of the miVac range into a fully integrated system. It includes vacuum tubing, a tube cutter, catch pot, and pump connection lead. Alternatively, system packages are available comprising concentrator, pump, cold trap and connection kit.
miVac are the only concentrators of their class to be supplied with rotors made from solid aluminium. The “JetRotors” range provides very high performance concentration compared to rotors made from plastic, or of an open construction. Speed increases compared with polypropylene types range between 40% and 200%, depending on sample format, providing a significant advantage when working with stubborn solvents, such as water. The precision solid aluminium rotors efficiently conduct the heat energy needed for concentration to the samples, whereas in an open or plastic rotor the samples are effectively insulated by the plastic and/or the vacuum in the chamber. Rotors are available for all common tubes, vials, centrifuge tubes and microcentrifuge tubes. A custom rotor service is also available to ensure that you gain best use of your system.
The miVac pressure controller can be added to any modular miVac system (or package) and allows the user full control over the running pressure in the system. A vacuum ramping mode enables concentration to be commenced gently and is used to help prevent bumping or spitting when evaporating solvent mixtures. For users who are uncertain of the appropriate pressures to choose, an automatic mode is available. Correct use of pressure control with the miVac SpeedTrap will make concentration faster and will enable more solvents to be caught in the SpeedTrap, reducing volatile solvent emissions.
A vapor wash bottle with either acid or ammonia neutralizing solutions is available for use when working these chemicals. Solutions change colour when exhausted indicating when they need to be changed. Traps are fitted after the pump and before the vapor is discharged to atmosphere or fume extraction system
