SpeedDry Vacuum Concentrators Fast and gentle

Gentle evaporation Samples are precious, and so is your time. With rotational vacuum concentration (RVC), you can prepare samples quickly without sacrificing gentle handling. This method can be used for evaporation, drying, purification and concentration. Rotational vacuum concentration can be a true alternative for anyone who has previously worked with distillation systems, rotary evaporators or freeze dryers. Distillation systems and rotary evaporators use high temperatures for evaporation and operate at nearly atmospheric pressure. They are fast, but not especially gentle. Freeze drying...

Exemplary functions and performance Our devices are distinguished by numerous functions and features that contribute to especially good performance. Variable-speed magnetic drive No bumping and no moving parts outside the rotor chamber. That way the chemicals stay inside the samples space. This reduces stress on the samples and on the device. Extremely simple operation The CDplus system controller is intuitive and especially user friendly. An automatic start/stop sequence independently controls vacuum application according to the rotor speed. Venting is also performed automatically to...

Intuitive system control Convenient and flexible Our SpeedDry vacuum concentrators have numerous user-configurable parameters for optimal process control and monitoring. Essential information, including time, vacuum, rotor speed and rotor chamber temperature, can be seen at glance on the well-organised graphical display. System parameters such as lid open/closed status and alerts with error codes are conveniently visualised. CDplus controller features • Well-organised graphical display • Indication of important process parameters • Large selection of languages • Vacuum measurement and...

Mini concentrator RVC 2-18 CDplus The mini concentrator is economical and compact. This bench device is specifically designed for the concentration of relatively small sample volumes and fits on every laboratory bench. Quick analyses at the workstation are easy with this device. It is ideal for gentle handling of DNA/RNA, proteins and other liquid samples. The mini concentrator is configured as standard with a chemicalresistant membrane pump with 2 m3/h suction capacity and an end vacuum of 7 mbar. A membrane pump with a higher end vacuum can optionally be used instead. The device is also...

HCl concentrator RVC 2-18 CDplus HCl Version Special samples need smart solutions. That's why we developed this mini concentrator with something extra: it can handle samples containing aggressive substances, such as commonly used in combinational chemistry or chemical decomposition methods. This model is a special version of the RVC 2-18 CDplus and has the same technical configuration as the basic device. It is compact and equipped with state-of-the-art technology. Users can choose from a wide range of rotors. The mini concentrator can be individually combined with a cold trap with glass...

Midi concentrator RVC 2-25 CDplus The midi concentrator is a general-purpose bench device for routine concentration tasks. Compact and efficient, it fits on every laboratory bench despite its high capacity. This device is suitable for gentle handling of DNA/RNA, proteins and other liquid samples. The composite stainless steel / glass lid with view window is made from corrosionresistant materials. The rotor capacity is impressive, covering the range from 108 x 1.5/2.2 ml vials to two microtiter plates The standard accessory membrane pump has a suction capacity of 2 m3/h and an end vacuum of...

Maxi concentrator RVC 2-33 CDplus The maxi concentrator is highly versatile and ideally suited to large samples volumes. Virtually all commonly used solvents can be handled perfectly with this device. The CDplus controller provides simple operation and outstanding process overview. The high-performance 1,550 rpm drive system reliably prevents samples splashing. The maxi concentrator is virtually immune to imbalance. The materials ensure long service life. The glass/steel composite lid with view window is corrosion resistant. The RVC 2-33 CDplus can be configured as standard with a...

High-speed maxi concentrator RVC 2-33 CDplus Infrared Version This Christ vacuum concentrator is especially suitable for effective concentration of solvents with high boiling points. The wide variety of available rotors ensures high samples capacity. Thanks to efficient energy input with halogen IR lamps, large samples volumes for active ingredient screening (e.g. 100 ml tubes) can be processed quickly. The innovative drive concept is especially noteworthy. The powerful external-rotor motor, contactless central rotary coupling and direct force transfer ensure safe operation, even under high...

Efficient, high-performance cold traps The evaporation rate is limited by two factors: the energy input (heating temperature and vacuum) and the suction capacity of the membrane pump. It is much more reasonable to use a cold trap as a cryogenic pump instead of a larger vacuum pump. Cold traps accelerate the process, especially with aqueous solutions. Cold traps • Capacity 2 l (CT 02-50) / 4 l (CT 04-50) • Condenser temperature -50°C • Easy emptying through bottom drain valve Freeze dryer used as a cold trap • Capacity 2 (Alpha1-2 LDplus) / 4 l (Alpha 2-4 LDplus) • Condenser temperature...
