The Haier HCP-258B is a 258 L (9.1 cu ft) air-jacketed CO₂ incubator that delivers a reproducible cell-culture environment with ±0.1°C temperature control and an IR CO₂ sensor accurate to ±0.1%, then decontaminates itself with 180°C dry-heat sterilization — no disassembly, no consumables. A 7-inch touchscreen, 304 stainless interior, and UL certification make it a core mammalian and stem-cell culture platform on a standard 115V outlet.

Application Profile
Cell culture succeeds or fails on two things: a stable 37°C / 5% CO₂ environment, and freedom from contamination. The HCP-258B addresses both directly. Six-sided heating under fuzzy-PID control holds temperature to ±0.1°C fluctuation and ±0.3°C uniformity, and after a 30-second door opening the chamber restores temperature and CO₂ within about 4 minutes — critical when multiple users share one incubator. CO₂ is measured by a new IR (NDIR) sensor with a silicon-MEMS emitter rated to 190°C: it withstands 300+ sterilization cycles, drifts less than 0.3% over two years, and needs no recalibration after high-temperature cycles.
Contamination control is the headline feature. The 180°C dry-heat sterilization cycle completes in under 12 hours and sterilizes all internal surfaces — including the CO₂ sensor — with no disassembly and no cleaning consumables, avoiding the secondary-pollution risk of removing and autoclaving components separately. The plasma-electropolished 304 stainless chamber with laser-welded radiused corners and bracketless shelving is quick to wipe down between cycles.
Design Architecture
The 7-inch touch screen responds even in gloves and shows live temperature, CO₂ (and optional O₂) concentration, with color-coded normal/abnormal status and USB export of up to 15 years of data. A comprehensive alarm system covers high/low temperature, excessive CO₂, water shortage, door ajar, sensor error, and remote alarm. A high-efficiency microbial filter on the CO₂ inlet removes ≥0.2 µm particles at 99.99%. Options extend the platform: HEPA filtration to ISO Class 5, an O₂ control module (1–21% or 5–90%), a water tray, roller base, inner doors, and a stacking bracket for double-stacking.
Frequently Asked Questions
How does the HCP-258B prevent contamination? A one-button 180°C dry-heat sterilization cycle sterilizes every internal surface — including the CO₂ sensor — in under 12 hours, with no disassembly and no consumables.
How precise is the temperature and CO₂ control? Temperature holds ±0.1°C fluctuation with ±0.3°C uniformity; the IR CO₂ sensor is accurate to ±0.1% over a 0–20% range.
How fast does it recover after opening the door? Temperature and CO₂ restore within about 4 minutes after a 30-second door opening.
Does the CO₂ sensor need recalibration after sterilization? No — the IR sensor withstands the 180°C cycle (300+ cycles, ~15-year life) and needs no recalibration afterward.
Can I add O₂ control or HEPA filtration? Yes — an O₂ module (1–21% or 5–90%) and a HEPA system reaching ISO Class 5 are both optional.
Ordering & Configuration
The HCP-258B is a capital purchase: request a quote for pricing and lead time. Backed by Haier Biomedical's manufacturer warranty — confirm current terms with your quote.
Choose the HCP-258B when you want large 258 L culture capacity with contamination control built in — 180°C dry-heat sterilization that spares the CO₂ sensor and skips consumables. Step down to the HCP-168B or HCP-80B for smaller footprints, and add the O₂ module for hypoxia/physioxia work.
