RVC 2-33 CD


RVC 2-33 CDplus


Another business activity since over 15 years is the production of rotational-vacuum-concentrators ("RVC"). Here, the close relationship between the Martin Christ company and Sigma Centrifuges offers obvious advantages in construction and production demands.

The Christ RVC-series is well structured in size and combination with different cooling traps and vacuum pumps. This gives the customer a maximum benefit for every application.


Examples for multiple applications:

  • Efficient concentration of DNA/RNA-samples, proteins etc.
  • BioTech and Genetic Engineering
  • Sample preparation in HPLC, GC, MS, Electrophoresis ...
  • Isolation and synthesis of natural compounds
  • Storage and handling of drugs (chemical libraries)
  • Combinatorial Chemistry
  • High-Throughput-Screening (HTS)

Performance characteristics

+ the maxi concentrator: a multipurpose system for large sample volumes with practically all types of solvents
+ rotor capacity 216 x 1,5/2,2 ml tubes up to 12 x microtiter-plates or 4 x deepwell plates
+ stainless steel/glass compound cover with window (corrosion proof)
+ high-performance system, 1.550 min-1 (500xg for micro-tubes) prevents bumping and foaming (e. g. with DCM)
+ practically tolerant to imballance (> 50 g)
+ chemical resistant diaphragm pumps (2m3/h suction capacity, 9 mbar final vacuum), standard, vacuum system with lower vacuum and vacuum controls, optional,chemical hybrid-pump for solvents with high boiling points (e. g. DMSO)
+ recommended use with 4 liter cooling traps due to high volume evaporation (-50, -60, -90 oder -105°C)
+ optional strobe light for monitoring of the evaporation process
+ flexible use as vacuum drying chamber through easy dismantling of rotor shaft
