*New extended range is important for GxP applications to reduce potential incident event reporting.

The integrated microprocessor control aggregates information from the entire system and compares to normal or setpoint values. Out-of-compliance events are announced by visual and audible warnings, and remote alarm when connected to an external system.

All performance attributes are displayed on a large, visually intuitive alpha- numeric display.

Internal temperature log files are expressed in graphical form over time.

Out-of-compliance events are announced by visual and audible warnings. Error codes quickly identify problem sources and permit fast diagnosis and remediation.

MDF-U500VXC, MDF-U700VXC specifications

The Sanyo MDF-U700VXC and MDF-U500VXC models are compact and efficient commercial freezers designed for laboratory and medical applications. These products are lauded for their reliability, precision temperature control, and user-friendly features. Both units cater to institutions that require secure and consistent storage for temperature-sensitive items.

One of the standout features of the Sanyo MDF-U700VXC and MDF-U500VXC is their advanced cooling technology. They utilize a hybrid refrigeration system that combines both natural refrigerants and cutting-edge compressor technology. This not only ensures a stable cooling environment but also minimizes environmental impact by using eco-friendly refrigerants. The temperature range for both models typically spans from -20°C to -30°C, making them ideal for preserving biological samples, pharmaceuticals, and other sensitive materials.

Another prominent characteristic is the temperature accuracy and uniformity. Both units are equipped with sophisticated microprocessor-controlled temperature management systems that maintain precise temperature levels. Additionally, integrated alarms and monitoring systems provide alerts in case of temperature fluctuations, ensuring that the stored contents remain undisturbed and protected. This feature is crucial in laboratory environments where product integrity is paramount.

The MDF-U700VXC has a larger capacity compared to the MDF-U500VXC, appealing to users who need to store a significant number of samples or larger items. However, both models are designed with space efficiency in mind, featuring adjustable shelving and a well-organized interior that allows easy access to stored materials. The exterior is crafted for durability, with a robust construction that can withstand the rigors of daily use in busy environments.

Energy efficiency is another key consideration in both models. They are designed to minimize power consumption while maintaining optimal performance, which is a critical factor in reducing operational costs for laboratories and medical facilities.

Both Sanyo models feature user-friendly interfaces, making setup and operation straightforward for staff members. Optional accessories such as external temperature recorders can further enhance usability and compliance with safety regulations.

To summarize, the Sanyo MDF-U700VXC and MDF-U500VXC represent cutting-edge solutions for temperature-sensitive storage. Their advanced cooling technologies, precise temperature control, user-friendly design, and energy efficiency make them essential assets for any laboratory or medical facility striving for excellence in sample preservation.
