11 equipment available

JP Selecta laboratory and pilot-plant reactors in borosilicate 3.3 glass and AISI 316L stainless steel: jacketed units from 500 ml to 100 L, mechanical agitation with sealed PTFE guides and thermal control from −50 °C to 400 °C. Compliant with ISO 3585 and suitable for ICH Q7, Q9 and Q10 validation.

JP Selecta laboratory and pilot-plant reactors

JP Selecta laboratory reactors provide a controlled environment for chemical and biochemical reactions that require precise regulation of temperature, agitation and pressure. The range includes jacketed borosilicate 3.3 glass reactors from 500 ml to 100 litres, and modular pilot-plant systems for production-scale pre-validation.

All units support uniform tempering through circulation of thermostatic fluid across the jacket, with mechanical agitation, temperature control and accessories configurable per process.

Our reactor range

Our reaction-system line covers everything from analytical microvolumes to complete semi-industrial processes, ensuring predictable, safe and efficient scale-up.

Glass laboratory reactors

This line is designed on demand for maximum technical flexibility in bench configurations built in high-thermal- and chemical-resistance borosilicate 3.3 glass, combined with pure-PTFE internal contact elements.

  • Standardised capacities: 0.5 L, 1 L, 2 L and 5 L.
  • Compatibility: Heidolph stirring systems.
  • Operation: suitable for atmospheric pressure or vacuum (up to 400 °C).

Stainless steel reactors

Robust instrumentation built to withstand intensive use and demanding mechanical conditions. Manufactured strictly in AISI 304, AISI 316 or AISI 316L stainless steel with mirror-polished finish.

  • Standard configurations: 6 and 12 L.
  • Structure: reinforced frames.
  • Heating: external 1500 W ceramic clamp heaters (up to 400 °C) or internal stainless steel coils for thermal fluids.

Pilot-plant reactors

Integrated systems on self-supporting wheeled frames geared to pilot scale-up and medium production. Double wall of transparent borosilicate 3.3 glass with integrated volume graduation.

  • Volumes: 5, 10 and 20 L; high capacity 50 and 100 L.
  • Agitation: 0 to 500 rpm (or up to 1450 rpm on special models).
  • Temperature/pressure: from −50 °C to 200 °C.

Jacketed reactors for precise thermal control

The jacketed reactor circulates a thermostatic fluid between its two glass walls, eliminating thermal gradients and enabling highly reproducible linear heating or cooling ramps.

The glass bodies comply with ISO 3585 and the pressure or vacuum joints are designed per ASME BPVC, supporting validation under ICH Q7, Q9 and Q10 in pharmaceutical and biotech environments.

Mechanical stirring system: Integrates an induction motor coupled to sealed PTFE guides and interchangeable shafts.

Multi-port lid and control accessories. Five ground-glass standardised ports at specific angles to simultaneously host addition funnels, Dimroth reflux condensers, charging stopcocks and sheaths for internal-control Pt100 probes.

Adjustable mechanical support and drain valve. AISI 304 stainless steel tubular structures with safety-ring fixing clamps. The base includes a PTFE drain valve with no dead spaces.

How to request a quote for reactors equipment?

You can request a quote through our website contact form, by email (selecta@jpselecta.es), or by contacting our sales team directly at +34 93 770 08 77. We offer personalized advice.

How do I choose the right reactor capacity for my work scale?

The choice should be based on the net reagent volume and on the headspace needed for vapour condensation or substance addition. As a general analytical rule, the liquid volume should never exceed 70–75 % of the vessel's nominal capacity. For early experimental phases or high-cost reagents we offer micro and bench reactors from 250 ml to 5 litres. If you need to process small pre-industrial lots or batch validations, choose pilot-plant reactor configurations from 10 to 100 litres.

What is the difference between a glass and a stainless steel reactor, and when to use each?

The borosilicate 3.3 glass laboratory reactor stands out for its full transparency (essential to observe colour changes, phase transitions or crystallisations) and for its universal chemical resistance against strong acids. It should be used in pharmaceutical and general organic synthesis. By contrast, stainless steel reactors (AISI 304/316L) offer infinitely greater structural mechanical resistance to impacts and pressures, and allow working with extremely viscous fluids (up to 1,000,000 mPas) or industrial processes where direct visual inspection is not required.

What stirring system do I need depending on the process or sample viscosity?

For low-viscosity fluids and water-like densities (e.g. distillations or standard dissolutions), PTFE propeller-shaped stirring shafts provide fast, efficient axial flow. If working with biological suspensions, cell cultures or fluids prone to sedimentation, choose anchor-shaped paddles that sweep the reactor bottom while minimising splashing. For medium or high viscosities at pilot plant, integrate high-torque synchronous motors with folding paddle systems or high-power dispersers.

Can JP Selecta laboratory reactors work under pressure or vacuum?

Yes — all our modular pilot-plant lines (RE-605 to RE-6100 series) are technically ready as standard to operate either at atmospheric pressure or under severe vacuum conditions (useful to lower the boiling point of heat-sensitive solvents or to degas mixtures). Vacuum is maintained via stirring guides with high-friction sealed PTFE joints, flexible expansion bellows and high-vacuum greases that tolerate suction pressures down to 10⁻⁶ mm Hg with no systemic leaks.
