Select to suit your budget

Choose the units you need. Add more at any time.

BioTOWER grows with you: from a single unit, to multiple units, to a full parallel system. Each reactor/Tower unit is totally independent and able to support both glass and metal (pressure) reactors of different sizes, and further units can be added at any time.

1single unit

A Tower and PC running one reactor: a low-cost way in.

+1multiple units

Add further reactor/Tower units at any time, as your work and budget grow.

8in parallel

Up to 8 independent units side by side, glass and pressure together.

A low-cost start that grows with your needs

Start with one unit.

One reactor/Tower unit: a Tower and PC running one reactor of the size and type you choose. A low-cost way in.

Swap the reactor, not the system.

Glass from ~50 mL to larger, or metal (pressure) reactors up to 10 bar, all on the same Tower.

Add units at any time.

Each further reactor/Tower unit adds a parallel reactor: anywhere from 2 to 8.

Never start over.

Every unit is totally independent, so your first one stays part of the system as you grow.

Affordable by design

Most bioprocess labs do not need a full parallel platform on day one. The BioTOWER lets you buy only what you need now, a single reactor/Tower unit, and expand at any time without starting again. Because reactor types and sizes are interchangeable on the same Tower, one investment supports work from ~50 mL screening to bench scale and beyond.

Low-cost start

One reactor/Tower unit runs one reactor of the size and type you choose. Start small, without paying for capacity you do not yet need.

Expand at any time

Add further reactor/Tower units whenever your work grows, up to 8 parallel reactors. Your first unit stays part of the system.

Totally independent units

Each reactor/Tower unit runs its own reactor with its own Tower and PC, fully automated.

Glass or metal, one Tower

Reactor types and sizes can be switched on the same Tower, so you do not need a separate control system for each scale.

Choice of interchangeable reactor systems

Reactors of different sizes are supported by the specified Tower and PC. For example, scale-up studies covering small (~50 to 500 mL), bench-scale (~1 to 5 litres) and larger reactors can be used with the single control system. High-pressure reactors run up to 10 bar.

BioTOWER glass reactors (~50-500 mL, ~1-5 L, larger) and high-pressure reactors up to 10 bar — **Glass reactors** (~50–500 mL, ~1–5 L and larger) and **high-pressure reactors** up to 10 bar (small and larger).

Frequently asked questions

Why is the BioTOWER affordable?

You select reactor/Tower units to suit your budget. Start with one unit, a Tower and PC running one reactor, and add further units at any time. Reactor types and sizes can be switched on the same Tower, so one unit serves several scales instead of buying a separate system for each.

What is the BioTOWER?

Powerful, affordable bioreactor systems, from one reactor to multiple, built from reactor/Tower combination units. Each unit is totally independent and supports both glass and metal (pressure) reactors of different sizes.

Can I start with one reactor and expand later?

Yes. The system can be expanded by adding further reactor/Tower units at any time, up to 8 parallel reactors.

What reactor sizes and types are supported?

Glass reactors from ~50–500 mL and ~1–5 L to larger, and stainless-steel high-pressure reactors up to 10 bar. Reactor types and sizes can be switched on the same Tower.

Which gases can be fed?

Each reactor has its own independently configurable mass flow controllers, from air and O₂ to H₂, CO, CO₂ and CH₄, with DO control to set point.

What sensors come as standard?

Temperature, pH and dissolved oxygen as standard, with redox, foam/level and optical density as options. Sampling can be manual or automated.

What monitoring options are available?

Optional BioVIS for inline, non-invasive cell-density monitoring, and optional Tandem off-gas analysis for real-time oxygen uptake rate, CO₂ production rate and respiratory quotient.
