Rotational-vacuum-concentrator RVC 2-33 CD plus

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.

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
