Zhi Chu CO₂ incubator shakers, also known as the advanced co2 incubator orbital shaker, integrate precise environmental control with orbital shaking, ideal for aerobic cell cultures, microbial fermentation, and protein expression. ZHICHU offers compliant co2 incubator orbital shaker products in multiple capacities with precise CO₂, humidity, and temperature control to optimize cell culture scalability.

Types of CO2 Incubator Shaker

Enhancing Protein Yield with CO2 Incubator Orbital Shaker

In protein research, maximizing yield is important. CO₂ incubator orbital shakers offer an integrated solution, combining precise temperature control, stable CO₂ levels, and uniform shaking to optimize cell growth and protein production. The controlled environment of the co2 incubator orbital shaker minimizes stress on host cells, ensuring higher protein expression. Meanwhile, the gentle yet consistent agitation promotes efficient nutrient uptake and gas exchange, critical for robust cell cultures.

For a closer look at how CO2 regulation supports culture-medium pH balance and cell growth, read our explanation of co2 incubator function.

For those utilizing a stackable CO₂ incubator, these features are essential for maximizing space efficiency while maintaining optimal conditions for protein research. The ability to stack units allows for increased capacity without compromising the precise environmental control necessary for high-quality protein expression and cell culture outcomes.

Advantages of ZHICHU CO2 Incubator Shaker Technology

Advantages of ZHICHU CO2 Incubator Shaker Technology

  • Superior chamber sealing: CO₂ concentration decreases from 5% to 4.5% in ≥30 minutes when powered off, a key stability feature of the orbital shaker co2 incubator by Zhi Chu.

  • Superior temperature uniformity: 9-point measurement ensures ≤±0.3°C deviation at 37°C setpoint under 25°C ambient conditions.

  • Precise humidity control via steam-generated humidification and optimized airflow circulation; eliminates contamination risks in high-humidity environments.

  • Antimicrobial SUS#304 stainless steel inner chamber with 99.9% bacterial inhibition rate eliminate cross-contamination risks in cell culture.

  • Advanced PID control integrates with remote monitoring systems for real-time surveillance.

Compare Models by Vessel Capacity, Orbit and Temperature Uniformity

Choose a co2 incubator shaker by matching your vessels, batch size, shaking conditions and temperature-uniformity requirement. The comparison below highlights the published differences between ZHICHU configurations, helping you shortlist a model before confirming holders, options and installation requirements.



Configuration and representative modelsCapacity or platform referenceOrbit diameter and speedTemperature uniformity at 37°CWhen to shortlist
Standard stackable co2 incubator: ZCZY-AN / AS8 / AS9 / ASERespectively 36 / 66 / 66 / 77 positions for 250 mL flasks with stainless-steel holders50 mm standard: 10–250 rpm; 26 mm optional: 10–300 rpm. Published speeds are no-load values.±0.3°CCompare these configurations when flask throughput and future stacking are priorities.
Stackable CO2 incubator shaker with rounded corners: ZCZY-ANR / ASR8193 / 306 L per chamber; respectively 36 / 66 × 250 mL flasks per tier50 mm standard: 10–250 rpm; 26 mm optional: 10–300 rpm±0.5°CConsider when the rounded-corner exterior and either chamber size fit your handling and capacity requirements.
High-precision stackable CO₂ incubator shaker: ZCZY-VANR / VASR8193 / 306 L per chamber; respectively 36 / 60 × 250 mL flasks per tier50 mm standard: 10–250 rpm; 26 mm optional: 10–300 rpm±0.3°CCompare when your specification calls for ±0.3°C uniformity; check tray capacity and dimensions against the standard stackable range.
High-speed, single platform: ZCZY-ARH / BRH / CRH193 L per chamber; one 575 × 435 mm platform3 mm standard: 10–800 rpm; 1.5 mm optional: 10–1200 rpm±0.5°CCompare incubator speed options for small-orbit protocols, then confirm plate or vessel compatibility.
High-speed, dual platform: ZCZY-ANRH / BNRH / CNRH193 L per chamber; two independently controlled 435 × 298 mm platforms3 mm: 10–1000 rpm±0.5°CConsider when comparative runs require separate shaking-speed settings within one chamber.
Floor-standing CO₂ incubator shaker: ZCLY-100168 L chamber; 485 × 410 mm platform; 488 mm internal effective height26 mm: 10–300 rpm±0.5°CCompare for a smaller chamber; the specification also lists a two-unit stacked configuration.
Floor-standing: ZCLY-180221 L chamber; 485 × 485 mm platform; 563 mm internal effective height26 mm: 10–300 rpm±0.8°CCompare when a larger platform and greater internal height are needed.


Check the configuration behind each figure. For the stackable ranges, A, B and C identify one-, two- and three-tier configurations within the corresponding model family. Chamber volumes are per chamber, not total stacked volume or liquid working volume. Flask counts refer to the stated flask size and holder arrangement; confirm the loading layout for your actual vessels.

All five product pages list 0–20% CO₂ control and a 4–60°C temperature range at an ambient temperature of 23–25°C. Automatic humidity control is configuration-dependent, so specify whether it is required in your quotation request. Confirm allowable speed with your actual load and selected orbit.

The high-precision and current standard stackable specifications both list ±0.3°C temperature uniformity at 37°C. Compare their capacity, dimensions and supplied options rather than selecting from the range name alone.

Request a model and configuration recommendation. Send ZHICHU your cell type, vessel dimensions and quantity, working volume per vessel, required orbit and rpm, temperature and CO₂ setpoints, available installation space and humidity-control needs. Include your preferred number of tiers so the quotation can address the complete configuration.
