Viscotek TDA 302 Triple Detector Detektor Array GPC SEC RID ELSD UV-2501 UV 2501

Manufacturer: Viscotek Model: TDA 302 Triple Detector Detektor Array + 2501 UV Detector S/N (TDA 302 (more) Triple Detector Detektor Array): 302-0604-190 S/N (2501 UV Detector): 76363 Description: The Model 302 TDA Differential Refractometer is the basic detector component of a system for polymer analysis by gel permeation chromatography (GPC), also called size exclusion chromatography (SEC). SEC involves separation through the hydrodynamic volume of the molecular distribution. The refractometer can also be used to determine the concentration of solutions after calibration. It is specifically designed for polymer analysis by SEC3 or FIPA.In an SEC3 system, the Deflection-type refractometers are the most common type used in SEC separation; they operate by measuring the deflection of a light source caused by a difference in the refractive index of a sample-solvent mixture and pure solvent. Because different polymer types have different differential refractive index responses with concentration (dn/dc), each polymer type must have a unique RI response factor. Therefore, the area of the RI is proportional to the product of the concentration, injection volume and inverse flowrate of the sample only across a single sample type. The RI area is exactly proportional to the quantity of the mass injected of the sample and its dn/dc value. The Model 302 TDA is designed to be directly to the outlet of a properly functioning HPLC pump by the minimum length possible of 0.01”id SS tubing.  The viscometer detector utilizes the patented technology of the four-capillary bridge to minimize the influence of flow rate fluctuations and maximize the sensitivity of detection. Accurate measurement of the polymer or protein concentration profile is essential to good molecular weight or structure data. The high-stability Viscotek UV-PDA 2501 is ideally suited for multi-detection GPC/SEC. The Viscotek UV-PDA is sold as an addition to the Viscotek TDAmax to complete a Tetra Detector format, or as a stand-alone module for connection to other chromatography components, such as the 270max system. Excellent tool for the compositional analysis of co-polymers or protein conjugates. UV-PDA allows the mapping of the molecular weight to the full UV spectrum. Precise and accurate temperature control as the detector cell is housed in the same thermal chamber as the rest of the system. Unmatched baseline stability and data reproducibility. Also available is a single wavelength detector.

Manufacturer: HTG Model: Firefly Imaging System P/N: 90006 S/N: FF-0025 YoM: 2008 Description: The  (more)FireFly is a high-quality, highly sensitive, luminescent imager with a charge coupled device (CCD) camera that can image multiple targets for an entire 96-well plate in about 15 minutes, allowing researchers to analyze samples directly at their workstation in the laboratory.The system optimizes imaging for HTG’s ArrayPlate qNPA™ technology; a high throughput array that enables multiplexed measurement of RNA levels, DNA expression and protein function. HTG’s ArrayPlate qNPA technology is used to carry out quantitative multiplexed, gene-based drug discovery programs, including target validation, HTS lead optimization, metabolism, toxicology and clinical development.The HTG FireFly Bench Top Chemiluminescent Imager has been specifically designed for use with qNPA kits for directly measuring gene expression on multiple targets simultaneously in a wide range of sample types including formalin-fixed paraffin-embedded tissues without the need for extraction or amplification. The imager allows laboratory researchers in smaller labs to perform studies that previously were not possible due to budget constraints. Applications: - drug discovery - molecular diagnostic such as target gene validation, gene expression screening and time course studies. - in vitro and in vivo pharmacology- metabolism and drug safety studies performing treatment profiling, dose response curves and compound optimization. Features: - Low background and exceptionally high resolution enables researchers to discriminate extremely small changes, < 20 %, in target gene level activity with great confidence, providing the highest quality data to make critical decisions in their research.- Ability to read partial plates allowing increased cost effectiveness in matching plate use to a research budget.- Expandable capacity to read additional formats planned for future software versions.- Simplified, robust optical design that allows high-quality gene-expression experiments on the bench. The HTG FireFly also has a small footprint.- Proprietary light amplification technology increases sensitivity without the need for a cryogenically cooled CCD chip.- The software has been designed to allow researchers sophisticated control over the imager. The instrument’s graphic user interface is intuitive and easy to use. This makes it ideal for multi-user environment where scientists can read plates quickly without overly complex instrument controls. Items delivered: - HTG Firefly Imaging System Condition: The item is in perfect cosmetic as well as working condition. It is 100% functional tested and ready to be operated.
