Description:
The Thermo Scientific Locator Rack and Box Systems simplify sample storage and retrieval with unique hanging rack and gridded box design, advanced vacuum insulation, and unmatched temperature uniformity. Includes four indexed stainless-steel vial racks. Outstanding temperature uniformity: samples are stored below -180°C even when less than 2" (5 cm) of liquid nitrogen remains in the vessel. Advanced vacuum insulation minimizes liquid nitrogen evaporation and reduces operating costs.
Specifications:
The Parker Balston® LC-MS NitroFlow Lab is a self-contained membrane nitrogen generator that produces LC-MS grade nitrogen with output pressure to 116 psig. Nitrogen is produced by utilizing a combination of compressors, care¬fully matched with filtration, and membrane separation technology components. Intake ambient air from the labora¬tory is filtered using an inlet suction breather filter to remove airborne organic and particulate impurities. This purified air is delivered to a long life low pressure air compressor which provides an air stream to hollow fiber membranes which subsequently separate the clean air into a concentrated nitrogen retentate and oxygen enriched permeate, which is then cycled through the system. Prior to exiting the system pure nitrogen retentate is delivered to a nitrogen amplification compressor to assure proper pressure, flow and purity to the LC-MS. The Parker Balston LC-MS NitroFlow Lab will deliver a continuous or on demand supply of pure nitrogen making it the smart alternative to cylinders. Superior engineering with carefully matched filtration, membrane separation and compression technologies have resulted in a system with the utmost reliability and longevity. Additional applications include: nebulizer gases, chemical and solvent evaporation, instrument supply and purge, evaporative light scattering equipment and sparging.

Description:
This state-of-the-art Cryogenic System can be used in either liquid or vapor phase. Worthington Industries K SERIES Cryostorage Systems are designed for applications where extremely low temperature storage of biological products is required. They are also appropriate for industrial or other applications where liquid nitrogen temperatures and high capacity are needed. The K SERIES style refrigerator is designed for, but not limited to, the laboratory environment. The standard model is equipped with a Worthington Industries approved electronic liquid level controller that will monitor and control the supply of liquid nitrogen to the unit.
Specifications:
Model 3300 ELSD is designed for use with High Performance Liquid Chromatography (HPLC) systems to analyze any sample compound that has sufficiently lower volatility than the mobile phase. Some of its possible application areas include carbohydrates, pharmaceuticals, lipids, triglycerides, underivatized fatty and amino acids, polymers, surfactants, nutraceuticals, and combinatorial libraries. Evaporative light scattering detection eliminates common problems associated with other HPLC detectors. Refractive Index (RI) detectors can be complicated by solvent front interferences, baseline instability, and gradient incompatibility. RI detectors can also have a less sensitive response than ELSD. Low-wavelength UV can suffer baseline drift with steep gradients and also requires that the analyte contains a chromophore. ELSD does not have these limitations. It can achieve stable baselines with multisolvent gradients for improved resolution and faster separations. Also, since ELSD response does not depend on the sample’s optical characteristics, the sample does not require a chromophore or fluorophore for detection.

Description:
The Worthington Industries High Capacity (HC) Series of cryogenic refrigerators is designed for long-term storage of biological material at liquid nitrogen temperature. Seven different models offer a variety of choices between sample storage capacity and holding time, while offering easier access to stored materials due to larger neck openings. Applications range from industrial to laboratory, biological and non-biological material. A low profile (12HCL) model is available for applications where a shorter unit is needed.
