StirCradle™

Stirred Tank Bioreactor Partner

StirCradle is a desk-type bioreactor/fermenter for microorganism culture. By combining the vessel, workbench, controller and peristalic pumps into one integrated system, this patented system effectively provides the most capacity for a small footprint. The StirCradle is ideal for research and development involving microorganism or animal and plant cell cultures.

Features

  • The patented design of the mixing system optimizes DO control during high density culturing
  • Can be used with oxygen enrichment devices and/or multiple gas devices to achieve ideal gas mix for cell culture
  • Vessel can be easily changed to suit different applications
  • Light weight and small footprint vs similar competitor models
  • Patented chassis thermal loop interchange design to provide the best temperature control
  • Four (4) built-in peristaltic pumps (with option to add up to 3 more) with assignable functions.
  • Two integrated USB port for ease of saving online data to external memory eliminating the need for a dedicated PC.
  • Datalog can record for up to 25 days with one (1) or two (2) minute/s intervals for all parameters.
  • 8”TFT Full ColorTouch Screen for Human-Machine Interface with easily replaceable panel membrane
  • Able to save up to 20 customized culture settings (with 50 culture conditions each)
  • Equipped with an easy-to-detach stainless steel condenser for easy cleaning
  • Can connect to downstream processing equipment to obtain high concentration of desired product
  • Exhaust gas analyzer can be connected to the internet for online monitoring
  • Free remote monitoring App viewable in smartphones, tablets, laptops or PCs (static IP address required)

Applications

  • Research and Development
  • Biopharmaceuticals
  • Proteomics
  • Laboratory-scale productions

Highlights

  • Real time data logging
  • Continuous recording up to 25 days with either 1 minute or 2 minutes interval per recording
  • Zoom in/out option
  • Integrated USB port for saving .xls files to external memory for data analysis and reports
  • The angle of the HMI monitor can be adjusted to provide a comfortable working environment for the operator
  • Vessel glass is made of either PYREX (U.S.) or SCHOTT (Germany) material.
  • Rigid, heat-proof, acid-proof and alkali-proof
  • Vessel base and support is made of stainless steel (SS316) that undergoes three manual polishing and electrolysis polishing (Ra<0.42µm)
  • The internal base of the vessel is designed with an arc to eliminate stagnation zone making it effective for culturing fungus or hypha.
  • Bottom heating plate has an integrated overheat protection and will not get hot when misused
  • The size of the heating plate is so small that it can fit into a medicine cabinet easily
  • Dynamic and interactive display for easy retention and reduced operator error
    • Real-time actuation with illustrated graphic effect
    • Real-time data display and recording
  • System can be equipped with 12 different impellers
  • Impellers can be applied with anti-stick coating if required
  • 1-1,200 operating rpm provides a wide range of culture shearing force
  • Patented Down Suction Distributed Impeller increases the amount of dissolved oxygen
  • User access is divided into eight (8) authority levels providing security to R&D or academic research data
  • Six (6) sensor/probe ports are located on the head plate allowing the operator to choose the configurations for probes and sensors
  • Four (4) assignable peristaltic pumps can be assigned for Acid, Alkaline, Feed or Anti-foam related activities. These pumps can be set as manual or automatic with adjustable speeds.
  • The system is made of stainless steel providing rigidity and easy cleaning
  • The 750w AC servo motor is brushless and maintenance free
  • Easy set-up. Simply mount the servo motor on the guided motor shaft.
  • Light weight and easily movable
