BIOSTELLAR Air-Jacketed CO₂ Incubator for Cell Culture, 50 L / 150 L

Model NO. RYX-50/RYX-150

The BIOSTELLAR CO₂ incubator provides a temperature-controlled, humidified environment for laboratory cell culture. Available in 50 L and 150 L capacities, it combines six-sided direct heating, an air jacket and gentle air circulation. An infrared sensor monitors CO₂ across a 0–20% control range, while a heated inner glass door helps limit condensation during operation.

Quantity

Features：

Two chamber capacities: Choose 50 L or 150 L to suit culture workload and available laboratory space.
Six-sided heating with an air jacket: Operates from ambient temperature +5°C to 55°C, with 0.1°C temperature resolution, ±0.1°C fluctuation and ±0.35°C uniformity.
Infrared CO₂ monitoring: Supports a CO₂ control range of 0–20%, with specified concentration fluctuation of ±0.5%.
Gentle circulation with door interlock: The fan and heating stop when the door opens, helping limit air exchange and heating overshoot.
Evaporative humidification: A water pan provides natural evaporation; the specified chamber humidity is ≥90% RH.
Chamber designed for cleaning: Rounded corners, a mirror-finished SUS304Cu stainless steel interior and a concealed UV lamp support routine chamber hygiene.
Double-door construction: A double-sealed tempered-glass inner door provides visibility, while inner-door heating helps reduce condensation. The outer door supports left- or right-opening configuration.
Operating controls and alerts: PID temperature control, a 0–9,999-minute timer, fixed-value and timed operation, menu locking, power-failure memory, and overtemperature, abnormal CO₂ and low-water-level alarms.

1. Which chamber capacities are available?
The range includes 50 L and 150 L versions. Select the capacity according to the number and dimensions of your culture vessels.

2. What is the operating temperature range?
The range is ambient temperature +5°C to 55°C. The lower limit therefore depends on the temperature of the room.

3. How is CO₂ measured and controlled?
The incubator uses an infrared CO₂ sensor. The specified control range is 0–20%, with concentration fluctuation of ±0.5%.

4. Is chamber humidity actively adjustable?
The supplied specification describes natural evaporation from a water pan and chamber humidity ≥90% RH. It does not specify an adjustable humidity setpoint.

5. What happens when the door opens?
The circulation fan and heating stop automatically to help limit air exchange and temperature overshoot.

6. What features support chamber cleaning?
The chamber has rounded corners and a mirror-finished SUS304Cu stainless steel interior. A concealed UV lamp provides supplementary disinfection of the water-pan area and circulating air.

7. Which alarms are included?
The specification lists overtemperature, abnormal CO₂ concentration and low-water-level alarms, together with power-failure protection and memory.

8. Is automatic switching between two CO₂ cylinders standard?
No. The source lists automatic dual-cylinder switching as an optional configuration. Confirm its inclusion when requesting a quotation.
