MDF-DU502VX-PE - HIGH-PERFORMANCE ULTRA-LOW TEMPERATURE FREEZER
The TwinGuard MDF-DU502VX-PE -86°C Ultra Low Temperature Freezer meets the industry’s demand for safe, long-term storage of highly valuable materials. Two independent cooling systems, supplemented by optional liquid nitrogen or liquid CO2 emergency cooling systems, provide unmatched protection on the market.
With two independent cooling systems, TwinGuard freezers maintain a reliable and consistent ultra-low temperature environment of -86ºC. Should one cooling system unexpectedly fail, the other circuit ensures safe cooling of irreplaceable samples at approximately -70ºC until repairs can be made.
Ultimate Sample Protection
The Dual Cooling System offers the best protection by utilizing two independent cooling systems. If one system unexpectedly fails, the other can maintain the freezer at -70°C. Store valuable and irreplaceable samples with the utmost confidence that they will not be lost in the event of a compressor failure.
Efficient Sample Storage
The combination of VIP PLUS vacuum insulation and improved cabinet design with an insulated outer door ensures optimal temperature consistency while maximizing storage capacity through reduced wall thickness.
Flexible Shelf Configuration
Multiple shelf configurations allow for a variety of storage options. Organize your samples using your existing storage racks.
Smart Interface
The EZ handle makes accessing stored samples even easier. A color LCD touchscreen allows full control by the user, even with gloved hands, while a USB port facilitates the seamless transfer of logged data to a PC.

LVL`D UP – What’s New, What’s Different?
A completely redesigned automation-friendly rack and tube take our long-term storage tubes to the next level. Join us and upgrade your sample storage. In addition to more than 13 different cap colors and countless possibilities for customizing tube and rack coding, we adapt your sample storage system to your needs and preferences.
The LVL Tube Laser Marker TLM 864:
Although the automation-friendly Data-Matrix code on the bottom of storage tubes has been standard for many years—and has greatly simplified sample handling—many users want to mark the tubes with their specific information. At the same time, they want to move away from time-consuming and unreliable labeling methods.
For this need, LVL has developed a fully automatic tube laser marker. The TLM 864 can automatically laser-mark SAFE® tubes in SBS 96, SBS 48, and SBS 24 formats from two sides and link the information in a database with the 2D code previously lasered during production. Up to 500 tubes per hour can be coded from nine SBS/ANSI positions.
