Lunaire CEO 958‑4 — Stability Test Chamber

The Lunaire CEO 958‑4 is a large‑capacity stability test chamber designed for ICH guideline testing, accelerated shelf‑life studies, steady‑state stability, package testing, burn‑in, curing, controlled temperature storage, and biomedical research. This model features a workspace of 58 cubic feet (1,642 litres) with interior dimensions of 60″ × 28.5″ × 60″ (W×D×H). Temperature range is from 0°C to +99°C with ±0.3°C control after stabilization and ±1°C uniformity in the 20–70°C range. Humidity range is 20% to 95% RH in the dry bulb range of +20°C to +85°C, limited by a 5°C dew point, with ±2% RH control and ±5% RH uniformity. The chamber features a highly efficient horizontal airflow system that provides maximum uniformity. Heating is provided by electric Incoloy‑sheathed tubular heaters, with a single‑stage reciprocating compressor using non‑CFC refrigerant and a Vapor‑Flo V Humidity Generator. The chamber includes a centrifugal type blower wheel with external mounted motor for air circulation. The controller features a high definition LCD display with four digital input lines. Standard equipment includes solid shelves. Options include RS 232 or RS485 communications, data logging and graphical trend chart, 5‑gallon water reservoir, recirculating system, water demineralizer, reverse osmosis system, condensate pump, external dryer for humidity levels as low as 5%, additional ports, additional stainless steel shelves, stainless steel exterior, heated viewing window, and interior lighting.
