  • ELISA processor (BIOBASE2000)

Fully automated ELISA processor (BIOBASE2000)

BIOBASE2000 Elisa Processors is fully automated Four-plate ELISA processing system, capable of sampling, incubation, washing and data processing. It is complete solution for your IVD ELISA assays. The system combines a high precision pipetting unit with stable incubators and efficiency washers and photometer unit.



  • 1 Robotic hand.

  • 2 Pipetting probe, 1ul stepping (1000ul volumes).

  • Total 25 racks, arbitrary rack can be defined as sample or reagent on the software.

  • 4 units 96 well microplates (pipetting,incubator,reading).

  • 1 unit independent washer & reader( two 8 nozzle manifolds).
