* The stated capacity rating represents the maximum achievable and is based on freeze drying plain water under ideal conditions. Individual results will vary depending on application and, in most cases, be less than the stated maximum. The FreeZone Plus Cascade Freeze Dry Systems have dual refrigeration systems that reach -84° C (-119° F) for samples with low eutectic points including ones containing acetonitrile.
