Product Features

Advanced technology and integrated electronics combine to allow the compressors to operate at a slower pace once the temperature set point has been attained and when the main door is closed. This provides less noise, less heat emission and lower energy consumption during daily operation.
Performance & Reliability
Robust refrigeration system with purpose built compressors that are made for the application. Unique internal heat exchange increases performance envelope, tolerates high ambient temperatures
Security Control
Optimal Security Convenience including facial recognition technology, keypad access and proximity card options to unlock the EZ latch electronic locking mechanism for cabinet access or adjustment of desired performance settings.
Large Intuitive LCD Touchscreen control panel interface which allows information to be viewed from various angles. This display allows for easy programming of temperature, monitoring of performance statistics and the ability to view displayed information from long distances. This model comes standard with USB Data Retrieval capabilities.
EZ latch
EZlatch Electronic Lock Door Assisting Handle is engineered to aid the users by pushing the door away from the cabinet frame during door openings and to provide greater efficiency when closing the door after loading/unloading the equipment. This handle is also built to tolerate frequent door openings, simplify one-handed access, and control frost build up.
My experience with DAI Scientific has been exceptional. I have come to appreciate the reliability of their products, the professionalism of their employees, and the readiness of their responses whether at the quoting, purchasing, delivery or setup stage. I have purchased multiple items from them over the years and their performance and endurance has been outstanding. I frequently recommend DAI to my colleagues and their experience has been as good as mine.

    Not all lab equipment suppliers are created equal. Here is why you should get a quote from D.A.I. Scientific:

    We work with a lot of lab equipment consultants and architecture and engineering firms to provide recommendations for new buildings or renovations. But we’re your resource no matter what. Companies continually call us for ideas and recommendations on equipment purchases even after a project is finished, and we’re happy to help.
  • 50+ Years of Experience
    We’ve sold thousands of pieces of lab equipment, which means we know how to avoid common challenges and pitfalls that can occur during a purchase. If you need help with purchasing a single piece of equipment, or an entire lab for a new building, let our experience save you time, money and unnecessary headaches.
  • No Surprise Fees
    We believe in complete transparency, which means we won’t surprise you with any fees during the process. We’re up front about our pricing, and our goal is to help you understand the complete cost from order and delivery to setup and training.
  • Training
    Our experienced, factory-trained representatives have the specialized knowledge to answer your questions and help you pick out exactly what you need.
