Gradient Fractionation System

Added: Aug 28, 2016 2:12 pm The National Institutes of Health (NIH) /National Institutes of Allergy and Infectious Disease (NIAID) in support of the Laboratory of Viral Diseases(LVD) has a requirement for a Gradient Fractionation System from Brandel 8561 Atlas Drive, Gaithersburg, MD 20877. This is a brand name or equal solicitation in accordance with FAR 52. 211-6. The Brandel system has the following salient characteristics: Gradient is displaced from the bottom up. Displacement from the bottom up allows for a continuous absorbance profile as the gradient is displaced by a dense chase solution. System seals and punctures the bottom of most common centrifuge tubes. Zone broadening and mixing are minimized with upward bulk flow. Syringe pump provides a more even displacement than the pulsation associated with peristaltic pumps. Collect peaks by time, volume, signal threshold, signal slope or using multiple detector channels. Fraction collector accepts 12 different collection vessels from MiniVials to Prep funnels at flows up to 100 mL/min. The part number for this system is BR-188-176 with the following components UA-6, type 11 Detector with Chart Recorder, FCC-176 R1 Fraction Collector, 60-120-211 UA-6 Detector Cable, BR-186-5, Tub Piercer w flow cell and Syringe pump and 2137-188 Data Capture Software. Installation and Training and an option for an additional 1 year warranty is requested. The government will award a fixed price purchase order to theresponsible contractor who can provide the same or similar equipment, installation, training and maintenance.
