From start to finish, PurePep Chorus is designed for an efficient workflow. This includes the use of a completely new software platform designed with the productivity of the user in mind:

Intuitive menu guided workflow

  • Pre-programmed standard methods may be used as is, or as a template for customized methods
  • Grouping allows reaction vessels to be configured to run simultaneously or in different groups to run sequentially. Groups can run unique protocols so that peptides requiring different methods can be conveniently prepared in the same synthesis
  • Import sequences to easily create new syntheses
  • Program new syntheses while others are run
  • Reagent preparation and usage calculators save time and prevent mistakes
  • Email notification delivers peace of mind that your synthesis is running as planned
  • SafePep™ feature prevents side reactions and undesired byproducts.
  • Self-diagnostics and automated cleaning routines ensure flawless operation of the system
  • Designed for 21CFR part 11 compliance with user management, electronic signatures, audit trail, and easy-to-review reports provide maximum traceability



  • Choose number of peptides to be synthesized
  • Group according to synthesis protocols


  • Input coupling methods, excess, and resin for record-keeping and calculations


  • Add sequences from library or create new ones with editor
  • Insert idle or no AA cycles for special chemistry within groups


  • Use default bottle positions for amino acids and reagents or arrange as desired
  • Select location of Single Shot amino acids
  • Choose up to 8 different solvents and reagents for a synthesis


  • Assign standard or custom chemistry protocols
  • Add special programs for any cycle


  • Software calculates weights and volumes needed for all reagents, as well as theoretical yield and synthesis time


  • Start from the beginning or cycle of your choosing
  • Monitor UV and temperature data in real time
