Product Features

Environmentally Friendly Refrigerants
Naturally occurring hydrocarbon [HC] refrigerants are environmentally friendly and compliant with sustainability objectives for non-depletion of ozone.
High Performance Refrigeration
The refrigeration systems and variable speed inverter compressor respond to demands for cooling based on temperature setpoint, frequency of door openings, and ambient temperature. Strategic integration of embedded cooling coils creates a uniform coldwall surface for fast response at temperatures as low as -30°C top to bottom.
Smart Cabinet Design
This space saving lab freezer allows more installation options in crowded laboratories or warm hallways. The cabinet is fitted with six wire shelves of which five are adjustable. Painted steel interior surfaces simplify cleaning.
Microprocessor Controller and Alarms
The microprocessor-based temperature control system with LED display maintains accurate setpoint temperature to within 1°C over a range of -20°C to -30°C. Audible and flashing visual alarm lights supplement the setpoint deviation system to warn of parameter violations and loss of power.
Our company has grown significantly over the last ten years. One thing I know I can always count on is DAI and their rep, Brian Langenderfer, doing their part to keep us informed of specials on instrumentation, get us great pricing on quality inventory, and rapid response times on all communications, including quotes. Not only that, but they coordinate quality movers to come onsite upon delivery and help unpack, move, and set up equipment professionally.  What I also appreciate as a lab manager is having the DAI employees, like Brian, to support all installations, upkeep, and is available for general questions. As our one lab has now grown to four, I always make sure my lab operation peers use DAI as their first “go to” for equipment purchases. We are always impressed and never disappointed with our DAI experiences.

Why D.A.I. Scientific

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

    Since we directly represent the manufacturer, you get the best price available — unlike a distributor who buys the product and then marks up the price to you. We have long term relationships with these manufacturers that provide not only a great price but superior equipment packages.
  • Providing the Right Recommendations
    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. They can also help you set up your equipment, provide training for you and your lab technicians and answer questions over the lifespan of your product.
