An incubator shaker is one of the most reliable and hardworking instruments in a lab. From microbial culturing to protein expression, its dual role, shaking and maintaining a controlled temperature, makes it a cornerstone of many biological workflows. But even the most robust equipment demands care. Without consistent maintenance, performance dips, errors increase, and downtime becomes unavoidable.
For lab managers and technicians, knowing how to maintain an incubator shaker is more than a checklist. It’s about protecting the integrity of experiments and extending the lifespan of a costly device.
Understand the Core Components
Before setting a maintenance routine, it helps to know what needs attention. An incubator shaker typically includes:
- A temperature control system
- A shaking platform
- A motor drive
- A chamber with internal sensors
Each of these components works in harmony. If one underperforms, the entire unit is compromised. For instance, debris around the shaking mechanism can affect motion uniformity, while a poorly calibrated temperature sensor can throw off sensitive cultures.
Routine Checks to Prioritize
Daily, wipe down the interior chamber and remove any spilled media. Moisture buildup and residue may seem harmless, but they often contribute to corrosion and microbial contamination. Schedule a weekly check of the platform to ensure it’s balanced and secure. Loose screws or uneven placement can strain the motor over time.
Temperature and speed settings should also be verified regularly. If your incubator shaker includes a digital display, compare the readings with an external calibrated thermometer and tachometer. Inaccurate readings may indicate sensor drift or internal wear.
When using models such as the SCI-O180-S Orbital Digital Shaker from NE LabSystems, consistent RPMs and smooth platform motion are critical. Their equipment is engineered for long-term use, but user vigilance helps prevent small issues from becoming major disruptions.
Cleaning Procedures
Use a non-corrosive disinfectant to clean the interior surfaces. Avoid bleach or strong solvents unless confirmed compatible with your model’s materials. Rinse with distilled water to prevent mineral deposits, especially if your lab has hard tap water.
Avoid spraying cleaning solutions directly into fans or electrical panels. Instead, apply with a cloth and clean around sensitive components. The door seal should also be wiped down weekly to maintain an effective seal and a stable internal environment.
Periodic Calibration and Inspection
Depending on usage frequency, schedule internal calibration and inspection at least once or twice a year. This includes checking temperature uniformity, shaking speed accuracy, and belt or bearing wear. Many labs coordinate this with annual equipment validation procedures.
For teams using NE LabSystems equipment, they offer calibration support and access to replacement parts tailored to each model. Their factory-trained service engineers can assist with maintenance planning that minimizes downtime.
When to Replace or Upgrade
Even with routine care, incubator shakers have limits. If your unit no longer holds a consistent temperature, produces unusual noise, or vibrates irregularly, it may be time for repair or replacement. Rather than wait for failure, many lab managers opt to replace older models proactively to maintain experimental reliability.
The product line at NE LabSystems includes shakers with programmable settings, quiet motors, and durable construction. Whether you’re running basic bacterial growth or advanced tissue cultures, they can recommend the right upgrade to match your lab’s goals.
Final Note
Maintaining your incubator shaker isn’t just about cleanliness. It’s about performance, reliability, and safety. Small habits, checking screws, cleaning chambers, and verifying RPMs translate to consistent results and fewer surprises.
