Overview
The WIGGENS Celshak CRC/SRC/MRC Series are precision-engineered orbital shakers specifically designed for integration within CO₂ incubators used in mammalian cell culture, stem cell expansion, and bioprocess development. Unlike conventional shakers, these units employ contactless electromagnetic induction drive technology—eliminating mechanical brushes, gears, or belt-driven motors. This architecture delivers high-torque oscillation while generating negligible heat (95% RH environments, while the user interface remains fully externalized via a dedicated remote controller.
Key Features
- Electromagnetic induction drive system ensures brushless, maintenance-free operation with exceptional torque-to-heat ratio
- IPX4-rated moisture resistance: epoxy-coated motor windings and sealed internal electronics for reliable performance in high-humidity incubator environments
- External remote controller (155 × 95 × 25 mm, 0.5 kg) with LED display enables real-time monitoring and parameter adjustment without opening the incubator door—reducing CO₂ loss, thermal disturbance, and contamination risk
- Thin-profile feedthrough cable (≤3 mm diameter) passes through standard incubator glass doors via factory-sealed ports; no internal power outlet required
- Mounting flexibility: controller attaches via integrated neodymium magnets or hook-and-loop straps to incubator exterior surfaces or top panel
- Microprocessor-based PID control with ±1 rpm resolution and programmable ramp-up/down profiles for sensitive suspension cultures
- Orbital motion pattern (25 mm standard, 50 mm optional) optimized for homogeneous suspension of adherent and non-adherent cell lines in flasks, multiwell plates, and bioreactor vessels
Sample Compatibility & Compliance
The Celshak platform accommodates standard tissue culture formats including T-25 to T-225 flasks, 6–96-well plates, Petri dishes, and Erlenmeyer flasks (capacity range: 100 mL × 16 up to 2000 mL × 2, depending on model). All contact surfaces are constructed from medical-grade 304 stainless steel with electropolished finish to support ISO 13485-aligned cleaning protocols and prevent biofilm accumulation. The device complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and its operational parameters align with GLP/GMP environmental monitoring requirements for cell banking and therapeutic manufacturing. While not certified under FDA 21 CFR Part 11, audit trails and parameter logging can be implemented via optional RS-232 or USB interfaces when integrated with validated LIMS or ELN systems.
Software & Data Management
The Celshak series operates via embedded firmware with non-volatile memory retention for all setpoints (speed, time, amplitude) across power cycles. The remote controller provides real-time display of actual RPM, elapsed time, and remaining runtime. For traceability-critical workflows, optional data export modules enable timestamped CSV logging of operational parameters at user-defined intervals (1 s to 60 min). When deployed in regulated environments, the system supports manual calibration verification per ASTM E2500–21 (Standard Guide for Specification, Design, and Verification of Pharmaceutical and Biopharmaceutical Manufacturing Systems) through documented procedure execution and operator sign-off.
Applications
- Suspension culture of CHO, HEK293, and hybridoma cells under controlled CO₂ and temperature conditions
- Stem cell expansion in serum-free or chemically defined media requiring gentle, consistent agitation
- Microcarrier-based adherent cell culture in spinner flasks and wave bioreactors
- Long-term microbial fermentation studies where oxygen transfer efficiency depends on orbital mixing intensity
- Drug screening assays using 3D spheroid or organoid models maintained in rotating bioreactors
- Antibody production workflows requiring scalable, incubator-integrated shaking during upstream processing
FAQ
Can the Celshak shaker be installed in any CO₂ incubator?
Yes—provided the incubator features a dedicated cable port or a glass observation door with sufficient clearance (≥3 mm gap) for the feedthrough cable. No internal power socket is required.
Does the shaker generate electromagnetic interference (EMI) that affects CO₂ sensor accuracy?
No—the electromagnetic drive operates at a fixed 50/60 Hz frequency synchronized with mains supply and includes built-in EMI suppression filters compliant with IEC 61000-6-3 Class B limits.
Is sterilization compatible with the shaker’s construction?
The stainless steel platform and epoxy-encapsulated motor tolerate routine surface disinfection with 70% ethanol or isopropanol. Autoclaving or dry-heat sterilization (>121 °C) is not recommended.
What is the maximum allowable ambient temperature for external controller operation?
The remote controller is rated for continuous operation at 5–40 °C ambient, making it suitable for placement on standard laboratory benchtops adjacent to incubators.
How is speed calibration verified?
Each unit ships with a NIST-traceable calibration certificate. Field verification can be performed using an optical tachometer or laser Doppler vibrometer against the displayed RPM value.
