Benchtop Electric Mini Fermenter

Single & parallel autoclavable
stirred mini-fermenter/bioreactor

Solaris Lab


IO is a completely electrical mini fermenter/bioreactor with a fast and accurate thermoregulation system (without water circulation).
With total volumes of 200ml or 1000ml, it represents an innovative device for process development and media optimization.

Solaris IO

Features and benefits

Single-wall borosilicate glass vessel, with thermoregulation performed through a Peltier Cell (no need for an external chiller/water supply).
Different configurations available for microbial (aerobic/anaerobic) and cell culture applications, with the choice of Rushton/Marine/Pitched-Blade impellers and fluted/L-shaped sparger.
Wide range of measurement and control options, including temperature, pH, dO 2,   dCO 2, redox, antifoam, level, conductivity, weight, cell density (total cells, viable cells).
Modbus digital sensors reduce background noise and guarantee quick response time.
Suitable for batch, fed-batch and continuous processes.
LEM01, the PLC-based control system supplied with the unit, integrates 4 fixed or variable speed peristaltic pumps.
Powerful and accurate (1 RPM) brushless motor.
LEM01, the PLC-based control system supplied with the unit, integrates 4 fixed or variable speed peristaltic pumps.
Different gas mixing strategies with up to 5 TMFC and/or solenoid valves.
Gas out can be optionally integrated with a condenser with Peltier Cell.
Extremely compact system maximizes lab space.

Frequenty Asked Questions

A compact benchtop bioreactor is the right measure between flasks and industrial-scale products. You get far greater control and precision over the culture process parameters than you would have using flasks, but still you can work with little volumes, avoiding wasting and cutting off costs. They are easy to handle, clean and sterilize. They let you remotely control the process, so you won’t have to loose a lovely seaside trip during the weekend just to feed your cells on a summer’s Saturday.
