Testing performed by our in-house service team:
The Kuhner ISF1-Z Peltier Incubator Shaker passed all tests and was found to be fully functional:
• We check the power.
• We test the displays and user interfaces of the controllers.
• We inspect the shaker bearings to ensure they are tight and in good condition.
• We reconfigure the system to meet customers’ requirements.
• We test shaking + full RPM range up to throw limits.
• We test the full temperature range (verified with NIST traceable calibrated equipment).
• We test the full humidity range (verified with NIST traceable calibrated equipment).
• We perform a stress test with simulated “under-load” conditions.

Instrument Overview:
• The Kuhner ISF1-Z Peltier Double Stack Incubator Shaker offers precise temperature and humidity control.
• Designed for high-throughput labs, it features two stacked units for doubled shaking capacity in a small footprint.
• This instrument provides uniform motion via Kuhner's orbital shaking platform, ensuring consistent culture growth.
• Temperature range is typically adjustable from ambient RT -5 DegC up to 60 DegC using Peltier technology for stable cooling/heating.
• The ISF1-Z system supports adjustable humidity to prevent culture evaporation during long runs.
• The Kuhner ISF1-Z is designed for durability and easy integration with existing laboratory infrastructure.

Instrument Application:
• Cultivation of microbial, insect, or mammalian cells under controlled temperature and humidity
• Protein expression in E. coli or yeast strains
• Fermentation process development and scale-up
• Long-term cell culture studies requiring stable conditions

The Key Features:
• Double stack design saves lab space
• Peltier system for cooling/heating
• Humidity control prevents evaporation
• Smooth, stable orbital shaking motion
• Wide temperature range, precise control
• Quiet, low-vibration operation

WHY DO CUSTOMERS MAKING CRITICAL LAB PURCHASES CHOOSE TO ORDER FLOOR SHAKERS FROM US?

They want to ensure the orbital shaking mechanism has been thoroughly tested under real load to confirm amplitude consistency and RPM stability across the entire platform, not just idled or spun unloaded.
________________________________________
They want to ensure the chamber has been disassembled and scrubbed down to ensure no spills or broken glassware is left behind to cause issues later on.
________________________________________
They want assurance that door seals, gaskets, and latch sensors are intact and tested, which is critical for stable thermal and gas environments.
________________________________________
They want to ensure that the temperature is not only accurate and tested against a NIST traceable probe but also proven to be stable over extended periods of time.
________________________________________
They want to ensure that onboard CO₂ and/or humidity regulation (if equipped) has been calibrated and verified using NIST-traceable, calibrated equipment, not guessed or assumed to be functional.
________________________________________
They want to know if the humidification system has been inspected and if the heaters have been tested for proper output.
________________________________________
They want peace of mind, knowing their instrument is backed by a warranty from a company that can stand behind it.
