Retention times vary slightly due to different bed lengths.

 

Reliability:

  • Reproducible column efficiency
  • Reliable hydraulic compression system, maintained by air pressure
  • Explosion-proof available
  • In accordance with European safety regulations

DAU-50

 

Safety:

  • Special hydraulics safety design:
    DAC hydraulics are separated from the column, thus there is no risk of contamination of the column bed with hydraulic liquid
     


Reproducibility of column efficiency

Ease of use:

  • Fast and simple column packing procedure
    (15 min, DAU 500-1000)
  • Optional slurry packing unit for convenient column packing available
  • Easy unpacking: Unpacking under sealed conditions via outlet tube to prevent dispersal of gel
  • Design of piston, column seals and frits allows easy dismantling and service

Flexibility:

  • Customisation of column dimensions is available on request
  • Compact design, mobile column stand
  • Column bed variable from 0 to 600 mm (larger dimensions available on request)
  • Suitable for virtually any packing material

DAU 500-1000

Safety:

  • Special hydraulics safety design:
    DAC hydraulics are separated from the column, thereby ensuring that there is no risk of contamination of the column bed with hydraulic liquid
