Product Description
MRC Labs TOS-3530CO2 CO2 Orbital Shaker
is a compact orbital shaker engineered for continuous use inside CO2 incubators and high-humidity environments. Its magnetic drive and sealed coil mechanism provide precise, maintenance-free motion with gentle start-up to protect cultures from splashing, while an external control box allows you to set and monitor speed and time without opening the incubator door. With a 355 × 300 mm platform, 19 mm orbit, and 30–300 rpm range, it accommodates a broad mix of flasks and bottles up to a 6 kg load. LED readouts show set and actual parameters for quick verification, and a 0–99:59 timer supports timed runs or continuous operation.
Applications
- Cell culture in CO2 incubators: Agitation of culture flasks and bottles under controlled CO2 and high humidity conditions.
- Bioprocess development and QA/QC sample mixing.
- Academic and clinical research labs requiring gentle orbital mixing.
Features
- CO2/high-humidity ready: Designed for use in CO2 incubators and humid chambers to support cell culture workflows.
- Maintenance-free magnetic drive: Sealed coils and magnetic actuation reduce wear and service needs.
- External controller: enables parameter adjustments without disturbing chamber atmosphere. Minimize door openings and stabilize temperature/CO2.
- Gentle start-up: Protects cultures from splashing and media loss during ramp-to-speed.
- Clear visibility: LED display shows both setpoints and actual values for quick checks.
- Flexible capacity: Supports a wide mix of vessel sizes with optional platforms, sticky mats, and clamps. (Sold separately.)
