Continuous flow
Feed enters and product leaves during operation.
Continuous Stirred Tank Reactors (CSTR)
Borosilicate glass continuous stirred-tank reactors for well-mixed, steady-state chemical processing as single vessels or controlled reactor cascades.

Continuous reaction
Hold a well-mixed process at steady operating conditions.
A continuous stirred-tank reactor receives reactants and removes product while agitation maintains a comparatively uniform composition and temperature throughout the vessel. The outlet therefore represents the conditions inside the reactor, making the CSTR a practical platform for steady-state flow chemistry.
Borosilicate glass provides corrosion resistance and direct process visibility for kilo-lab, pilot and small-production duties. Heating or cooling can be supplied through a jacket or bath, and automated controls can be incorporated around flow, temperature and agitation.
Well mixed
Agitation promotes uniform bulk conditions.
Thermally controlled
Jackets or baths add or remove process heat.
Automation ready
Flow and process controls can be integrated.
Salient features
Designed for controllable continuous processing.
The vessel and control arrangement can be matched to reaction rate, residence time, phase behaviour and heat-transfer demand.
Steady-state operation
Reactor conditions are maintained while feed and product flow continuously.
Uniform process conditions
Effective mixing limits gradients in temperature, density and concentration.
Broad reaction duty
Suitable for exothermic, isothermal and endothermic liquid-phase reactions.
High-agitation applications
Useful where viscous or immiscible liquids require strong mixing.
Heat-transfer options
A vessel jacket or external bath can supply or remove heat.
Process visibility
Glass construction lets operators observe flow, mixing and phase behaviour.
System arrangements
Choose a single CSTR or a controlled reactor cascade.
Residence-time and conversion requirements determine whether one vessel or multiple reactors in series provide the better process fit.
Single continuous stirred-tank reactor
One well-mixed stage for steady-state processing
A single CSTR provides a straightforward continuously fed and discharged reaction stage with agitation and thermal control.
Process characteristics
- Flow pattern
- Continuous feed and product withdrawal
- Mixing
- Well-mixed vessel contents
- Outlet condition
- Representative of the reactor bulk
- Typical phase
- Homogeneous liquid reaction
CSTR cascade
Multiple stirred reactors operated in series
Three- or four-reactor cascades can improve residence-time control and reduce back-mixing when a single vessel cannot deliver the required conversion or process behaviour.
When to consider a cascade
- Reaction rate
- Slow reactions requiring more controlled residence time
- Fluid behaviour
- Viscous or immiscible phases requiring high agitation
- Conversion
- Processes targeting higher reactant conversion
- Typical arrangement
- Three or four CSTR stages
