SANYO North America Corporation (SANYO) Biomedical Solutions Division announces its new, larger 25.7-cubic foot Twin Guard Series™ -86°C Ultralow Temperature Freezer, the MDF-U700VXC, featuring Dual° Cool™ technology.

The Twin Guard Series™ is designed to preserve the most sensitive, high-value biologicals and serves as the ideal critical storage appliance in repositories and medical research facilities. Allowing more flexibility in storage space, up to 576 boxes (2-inch), the MDF-U700VXC is available now through SANYO Biomedical sales representatives.

Twin Guard Refrigeration System
The MDF-U700VXC employs advanced Dual° Cool™ technology to maintain ultra-low temperatures by using two completely independent one-compressor, autocascade cooling systems. The system offers a way to securely store biological samples by serving as a fail-safe mechanism, with two independent refrigeration circuits that include a closed-loop, cold-wall evaporator configured parallel one to the other. In the unlikely event that a compressor fails, the remaining compressor will automatically continue to keep the interior chamber at a minimum of -65°C for an indefinite period of time.

SANYO-designed new generation Cool Safe™ refrigeration compressors also feature innovative refrigerant feedback processes to reduce compressor temperature, extending compressor life and minimizing heat output.

EcoMode™ and Energy Efficiency
A unique EcoMode™ deploys both systems in alternating cycles to maintain -86°C and reduce energy consumption in response to cooling demands. The evaporator coils have also been strategically embedded in SANYO’s patented VIP™ PLUS vacuum-insulated, thin-wall panel cabinet to deliver both the best temperature uniformity at all shelf levels as well as maximizing interior storage space. EcoMode™ is recommended and capable of handling 90-95% of applications.

Because of the two-in-one freezer design, no additional backup freezer or its additional footprint and energy use is necessary.

Advanced Control and Monitoring
Freezer functions are made simple through an integrated microprocessor-based control system featuring a high resolution LCD information center. The control and information center includes comprehensive setpoint, alarm, monitoring, diagnostic and communications functions for enhanced operability and visibility.

Other Standard SANYO Features

The MDF-U700VXC is also equipped with standard industry and SANYO features, such as:
• SANYO-patented V.I.P. Plus™ vacuum insulation panel cabinet construction
• Insulated and gasketed inner doors that seal inside
• Inner door latches
• Seismic restraints to secure cabinet to building superstructure to meet local codes
• HFC-refrigerants only
• Quiet operation
• Vacuum relief valve mounted on left wall for easy access
• Easy-In/Easy-Out™ door latch for easy one-handed operation
• Security features such as universal keyed door lock

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins. Find the best cell and tissue culture products, kits and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Cell Lines Stem Cells and Primary CellsPrimary cell cultures, established cell lines and stem cells are vital for <i>in vitro</i> and <i>ex vivo</i> experimentation. High-quality cells, optimized for your applications, alongside optimized cell substrates, growth medium and supplements, are critical for experimental success. Explore a range of cells suitable for your applications, including isogenic cell lines, competent cells, induced pluripotent stem cell (iPSC)-derived cell lines, fungal/bacterial/mammalian cell lines, stem cells and cancer cell lines. Find the best cells for your research in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Refrigerators Freezers and CryogenicsRefrigerators, Freezers & Cryogenics can be used for preservation or experimental purposes. Types of freezers include deep freeze, -80C°C, ultra-low temperature, explosion proof, cryogenic and controlled rate freezers. Freezing is also used in freeze-drying equipment for dehydration processes. Feature to consider in freezers include temperature control and recorders, failure alarms and self-closing mechanisms.Assay AssemblyAssay Assembly is technique used in drug discovery to develop assays to test the cytotoxicity, genotoxicity, or other activities of a compound on a cell. Assay assembly requires chip assembly, a delivery system and a detection and analysis method. Beneficial features of assay kits or automated systems include high-throughput, high speed and sensitivity and low signal to noise ratio.Medicinal ChemistryMedicinal chemistry is a broad discipline encompassing the design, identification, synthesis and development of chemicals in drug discovery. It includes a number of techniques covering structural biology, synthetic chemistry and molecular biology. Technologies used in medicinal chemistry include ADME, lab-on-a-chip, high content screening and assay assembly.Blood TransfusionBlood Transfusion involves giving donor blood to a recipient patient. Screening is essential to avoid transfusion reactions. Blood banks use immunohematological techniques to determine rh and ABO blood group, and screen for antibodies using specific antisera. Blood Banks use Direct Coombs Tests (DCT) and Indirect Coombs Tests (IAT) to detect hemolysis and Haemolytic Disease of the Newborn (HDN).HematologyIn Haematology / Hematology, complete blood cell counts (or full blood counts) are obtained using automated blood count analyzers to enumerate blood cell types.  Hematology also encompasses haemostasis and coagulation, thrombophilia and hemophilia, plasma viscosity and ESR analysis, hemoglobinopathies, cell morphology and haematinic measurement.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Cellular PathologyCellular Pathology deals with the microscopic analysis of tissue samples and cells. Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Clinical GeneticsMolecular Genetics covers the analysis of hereditary genetic disease and chromosomal abnormalities. Genetics can be analysed using DNA, RNA, and protein microarrays, PCR, RT PCR and DNA sequencing. Genetic equipment includes genetic workstations, thermal cyclers, cooling blocks and electrophoresis products. Diagnostic kits are used for DNA / RNA extraction and purification.
