StirCradle™-Pro

Stirred Tank Bioreactor Partner

The StirCradle-Pro is a fully stainless steel fermenter/bioreactor system designed with an automated 5-step cycle SIP system for both culture medium and reactor vessel. VacciXcell offers a wide range of standard reactor capacities from 20L up to 1000L; however, customized reactor sizes are available should the users require.

StirCradle-Pro features various advanced design and assembly to facilitate the fermentation/culture process including reactor design that eliminates blind spots and increases oxygen retention rate, lifting system for easy cleaning of reactor vessel, and LED light for easy viewing within the culture tank.

VacciXcell simplifies scale up from the laboratory to pilot and production scale by providing analysis data as reference for scale-up conditions. Apart from customized sizes, VacciXcell also offers parametric programming and special vessel development to help speed up the experiment. Vaccixcell offers complete documentation of system parts.

Sterilization in Place (SIP) Screen

  • SIP screen shows real-time view of sterilization process:
    • Shows the current step of the sterilization process
    • Shows open or close valves
    • Shows the present and set values for sterilization parameters: temperature, agitation, air, pressure, and time
  • 5-step sterilization process:
    • Heating 1 – 100% steam in heating jacket
    • Heating 2 – Steam in heating jacket and Air filter
    •  
    • Cooling 1 – Use of air for cool down system to 50 – 60oC
    • Cooling 2 – Use of chilled water/tap water to completely cool down system
  • Sterilization modules for both reactor vessel culture medium

Culture Screen

  • Real-time dynamic display of culture process
  • Shows the set value and present value of all parameters, open and closed valves, and total volume of liquid added by each pump
  • Users can switch between automatic and manual control of parameters
  • Shows the total culture time

Feed Setting Screen

  • Users can set the flow rates for each pump. Once flow rate for each pump is set, flow of each pump can be controlled via speed percentage.
  • Users can set the pump as one of the following:
    • On/Off: Users control pumping without depending on parameter values
    • DO Stat: Pumping is controlled by changes in DO value, depending on the criteria set by the user
    • pH Stat Pumping is controlled by changes in pH value, depending on the criteria set by the user

Step Control Setting Screen

  • Users can set a 50-step control program for temperature, agitation, pH, DO, aeration, and feeding
  • Up to 20 step programs can be saved for each parameter. Saved programs can be loaded, modified and deleted.
  • Users can select the point on a step program at which the program will begin
  • The 50-step parameter control is designed to ease and automate user control of the culture/fermentation process

Sterilization and Culture Setting Screen

  • Users can set the parameter values for the sterilization cycle and culture process
  • For sterilization process, users set the end temperatures for each sterilization step, agitation speed, pressure, airflow, and total time of sterilization.
  • For culture settings, users can choose to have automatic or step control of the parameters:
    • Automatic: controlled by the set value (SV) of the user
    • Step: controlled by the step setting of the user
  • Users can set one of the following DO control modes they require:
    • Agitation speed
    • Vent Control
    • Agitation speed -> Air -> O2
    • Vent -> Agitation speed -> O2
  • Users can designate one of the following settings for the peristaltic pumps:
    • None: no pump action
