Pilot-scale freeze dryers

Martin Christ pilot freeze dryers provide a powerful platform for process development, formulation work and small-scale production. With ice condenser capacities from 4 to 16 kg and single- or double-chamber configurations, the Epsilon range mirrors the geometry and control logic of full-scale production systems—ensuring reliable and predictable scale-up.

All models feature direct or fluid-cooled shelves, high-performance refrigeration and the intuitive LSCplus controller. Optional PAT tools such as LyoCam, LyoCoN, WTMplus 2.0, MTMplus and LyoControl offer unparalleled insight into nucleation, drying behaviour and product temperature.

Model overview:
Epsilon 1-4: 4 kg condenser, compact single-chamber design for routine R&D.
Epsilon 2-4: 4 kg condenser at –85 °C for more demanding formulations.
Epsilon 2-6D: 6 kg double-chamber unit for pharmaceutical-grade development.
Epsilon 2-10D: 10 kg condenser for mid-scale vial or tray batches.
Epsilon 2-12D: advanced process-development platform with full PAT toolkit.
Epsilon 2-16D: high-capacity pilot system with up to 1.44 m² shelf area, ideal for bulk or 24/7 pre-production. 
Epsilon 2-18D: 18 kg condenser, –75 °C, large shelf space (up to 1.51 m²) optimised for nested vials and protected trays (LyoGuard / Lyoprotect) in high-value biopharmaceutical applications.
