Industrial size HP-RFC columns combine small footprint with ease-of-use

Tripod HP-RFC columns: Smallest footprint highest throughput

HP-RFC columns will significantly reduce the footprint required for an industrial column. In the example below the 210-230L Tripod column  with a bed height of only 12cm can be nicely tugged away in a corner without compromising acces processing 6000L/h at 300cm/h.!  A perfect match with the popular disposable bad buffer totes that take up enormous space in the cleanroom. Thanks to Tripod HP-RFC now manouvered without risk of injury.

Proxcys wins Innovation Award

RFC Equipment producer Proxcys from Nieuw-Amsterdam is the winner of the ‘Voorloper 2015’, the Annual Innovation Award of Drenthe (Region North Netherlands).

Director and founder Marcel Raedts received the prestigious award Wednesday during the Innovation Conference in the Hampshire Hotel in Emmen.

Proxcys started twelve years ago as a sole proprietorship in the garage of Mr. Raedts’ home, nowadays it is grown into a global operating company.

,,A successful example of an innovating company, international operating from the region of the roots'' according the jury.

Proxcys won the price of 10 other nominations, second and third place were for; innovating furniture manufacturer Drentea and Ninthway, creator of the Care Watch.

Proxcys B.V. is the world's primary producer of high performance low pressure cGMP compliant radial chromatography equipment.
