Stackable CO2 Incubator

What is the Stackable CO2 Incubator?

A stackable CO2 incubator is built to be stacked two or three high with accessories, saving floor space in busy laboratories. It is chosen when bench and floor area is limited but culture capacity must grow.

Overview

The stackable incubator is engineered so units can be placed directly on top of each other, with reinforcing frames, matched footprints and optional stacking kits. Air-jacketed and direct heat designs are usual because they are light and warm up quickly. Each unit keeps its own controller, CO2 supply and alarms, so cultures remain independent, though a shared gas manifold is often used. Chamber volumes of 50 to 200 liters per unit are typical, with infrared CO2 control, humidity near 90 to 95 percent and optional high-temperature decontamination. Front-access doors allow use without unstacking, and casters help when units must be moved for service. It suits growing cell culture laboratories and core facilities that need more incubators in the same footprint.

How does it work?

A CO2 incubator heats an insulated chamber to a setpoint, usually 37 C, and adds carbon dioxide from an external cylinder to hold the medium pH near 7.4 in bicarbonate buffers. An infrared or thermal-conductivity sensor measures CO2, and a PID loop opens a valve or modulates gas flow to correct deviations. Humidity is maintained near 90 to 95 percent by a water pan or an active humidity generator, which reduces evaporation and keeps osmolality stable. Air circulation may be natural, forced or designed as a gentle laminar flow to limit contamination spread. Door heaters reduce condensation on the glass, and over-temperature and CO2 alarms protect the culture. Interior surfaces are stainless steel or copper alloy, chosen for cleanability and antimicrobial behaviour, with gaskets that allow frequent decontamination.

What are the key features?

• Reinforced frame for stacking two or three high
• Matched footprints and optional stacking kit
• Independent controller, gas and alarms per unit
• Air-jacketed or direct heat construction
• Front access without unstacking
• Casters for service movement

What are the technical specifications?

A typical stackable co2 incubator configuration offers chamber volume per unit of 50–200 L, stacking capacity of 2–3 units, temperature range of RT+5 to 55 C, temperature uniformity of ±0.3–0.5 C, CO2 range of 0–20% and CO2 sensor of Infrared (IR). Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Stackable CO2 Incubator is used in growing cell culture laboratories, core facility and shared platforms, multi-user culture rooms and laboratories with limited floor space. Across the wider CO2 Incubators class, laboratories also deploy it for mammalian cell line culture, tissue and primary cell culture and in vitro fertilization and embryo work.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, IEC 61010-2-010, DIN 12880, USP <1116>, ISO 14644-1, ISO 17025 and ISO 9001. Certification candidates for this model are CE, ISO 9001 manufacturing and RoHS; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Place the incubator in a stable location away from sunlight, draughts and heat sources, with space for the gas cylinder and regulator, and anchor cylinders so they cannot fall. Use instrument-grade CO2 and replace the water in the humidity pan with sterile distilled water regularly to avoid microbial growth. Decontaminate the chamber on a defined schedule, and monitor CO2 concentration, temperature and humidity daily, logging values. Verify temperature and CO2 with calibrated references at intervals and after service. Check door gaskets and filters for wear, keep the chamber loaded so temperature stays stable, and avoid stacking past the manufacturer's limit.

How do I select the right Stackable CO2 Incubator?

Select a stackable incubator when capacity must grow without adding floor space, or when several independent units are needed in one location. Confirm the stack kit, floor loading and gas manifold design. In the RFQ, specify units, volume per chamber, stacking height, CO2 configuration and decontamination options.

How does it compare with other CO2 Incubators variants?

Choose a CO2 incubator when the culture needs a bicarbonate-buffered medium and high humidity, which is typical of mammalian and tissue culture. Decide the heating design first: air-jacketed units are simple and recover steadily, water-jacketed units hold temperature through long power interruptions, and direct-heat units warm and cool quickly. Then set chamber volume from flask count and check the CO2 range and sensor type, since infrared sensors resist humidity drift better than thermal-conductivity sensors. Consider humidity method, decontamination options such as high-temperature cycles, HEPA filtration and stacking. Confirm gas supply, alarm connectivity and power, and require validation support for regulated cell work.
