Pharmaceutical R&D Laboratory – Germany

A mid-sized pharmaceutical R&D lab in Baden-Württemberg, Germany, specialized in custom API synthesis, needed a reliable glass reactor system for small-batch production and process validation. Their key requirements included precise temperature control (–20°C to +180°C), vacuum distillation capability, and explosion-proof operation for volatile solvents.

They selected the PGR-50 due to its 50L volume, 6 neck ports on the cover, and 0.098 MPa vacuum degree. The 140W motor with 50–600 rpm speed range and 2.23 Nm torque provided sufficient agitation for viscous reaction mixtures. The double jacketed design allowed circulation of hot oil and freezing liquid without cross-contamination.

*“The PGR-50 has become the centerpiece of our kilo-lab. Temperature stability is excellent, and the digital speed control on the BET56-B frequency box gives us reproducible agitation across batches. The explosion-proof motor (ExdⅡT6) gives our safety team full confidence. We have since ordered a second unit for our new cleanroom."

• Reduced batch cycle time by 25% compared to their old single-jacket reactor.
• Achieved consistent yields within 98–102% across 50+ runs.
• Successfully scaled up three new API candidates from 5L to 50L.

The German client also appreciated the 12-month warranty (excluding glassware) and the option for on-site commissioning, which they utilized for operator training.
