Biopharmaceutical Chromatography Systems. Chromatography is the collective term for a family of laboratory techniques for the separation of mixtures. Chromatography may be preparative or analytical. Preparative chromatography separates components of a mixture for further use. Analytical chromatography measures the relative proportions of components in a mixture. Ion chromatography is a process that allows the separation of ions and polar molecules based on the charge properties of the molecules. It can be used for almost any kind of charged molecule including large proteins, small nucleotides and amino acids.
Things to Consider: Flow range (L/hour), Piping inside diameter, Pipe connections, Dimensions, Uncrated weight, Working pressure, Working temperature range, Surface finish – internal, Operating environment (Temperature/Relative humidity), Electrical ratings (IP54/NEMA 13), Electrical and safety approvals (CE and UL), Quality systems (ISO9000), Design standards (ASME BPE, GAMP), CFR21 part 11 compliance, Number and type of pumps, Gradient/In-line dilution capability range (%), Number of inlets including product sample, Number of outlets including waste, Column flow control, Bubble trap, Filter type and micron rating, Air sensor, Instrumentation (Flow meter/Pressure transmitter/Conductivity/Temperature/pH/UV), Wetted materials (Pipework/Pumps/Valves/Bubble trap/Filter/Instrumentation/Elastomeric seals), Warranty.
Environmental Chambers: Equipment used to perform scientific testing of products under a variety of stresses and environmental conditions. These chambers can simulate environments with extreme temperatures, humidity levels, altitude, radiation, wind, bacteria, dust and chemical exposure.
Things to Consider: Temperature control, Humidity control, Light control, Safety thermostats, Timer, Controllers, Display, Programming, Adjuastable alarm limits, Sensors, Accessories, Fittings (Water filling port/Drain port/Max water pressure), Shelves (Dimensions/Max load per shelf/Permitted total load), Power requirements, Dimensions (Exterior/Interior/Volume of working chamber), Weight.
