QX200 Droplet Digital PCR System

Name and Model (Year of Manufacture / Installation)

Bio-Rad QX200 Droplet Digital PCR system (2014/2014)

General Information

A digital PCR system. Droplet Digital polymerase chain reaction (ddPCR) provides high-precision absolute quantification of nucleic acid target sequences. Bio-Rad’s QX200 ddPCR system combines water-oil emulsion droplet technology with microfluidics.

 The system consists of the following devices:

  • QX200 Droplet Generator
  • QX200 Droplet Reader
  • PX1 PCR Plate Sealer

Suomeksi: Digitaalinen PCR-laitteisto geneettiseen tutkimukseen.

Key Specifications and Features       
  • Droplet partitioning by the QX200 Droplet Digital technology reduces bias from amplification efficiency and PCR inhibitors.

PX1 PCR Plate Sealer (components):

  • Heat sealing instruments
  • Plate support block for 96-well plates
  • Sealing frame

Other features:

  • The touch-screen interface of the Plate Sealer instrument shows the instrument status, platen temperature, protocol name, set temperature, and time.
  • Sealing protocols can be stored and easily edited.
  • The sealer can be programmed to automatically shut down after a user-defined period of idle time. Touching the display after shutdown will reactivate the display and the sealer will begin heating to the last set temperature.
