Large volume all-stainless exterior and interior.

Thermo Scientific Heracell Vios 250i CR (catalog number 51033782) is a large-volume 255 L (9.0 cu. ft.) CO₂ incubator that is the first of its kind to be third-party certified as cleanroom-compatible for ISO Class 5 and GMP Grade A/B environments (in accordance with DIN EN ISO 14644-1).

This all-stainless model features an electropolished stainless steel chamber and brushed stainless steel exterior, with a compact, easily stackable (double-stack capable) design. The unit is designed for reliable cell culture conditions while meeting the stringent requirements of cleanroom and GMP environments.

Key features
Certified cleanroom and GMP compatibility — Third-party validated for ISO Class 5 and GMP Grade A/B environments; includes patent-pending Active Particle Control System to limit particulates released into the cleanroom; factory compliance package included.
All-stainless construction — 255 L electropolished stainless steel chamber; brushed stainless steel exterior casing with IP54 rating for superior cleaning compatibility in cleanroom settings.
Stackable large-volume design — Compact footprint that is readily stackable (up to two units); adjustable perforated shelving; direct-heat chamber.
THRIVE Active Airflow — In-chamber fan distributes clean, humidified air for homogeneous conditions; parameter recovery in 10 minutes or less; auto-stop function minimizes air exchange when the door is open.
