Used EG&G 307 #9239860 for sale

EG&G 307 is a laboratory device used for automated molecular weight determination. It is a four-wheel robotic system which can be operated via a computerized control unit and features an external environment chamber with a full range of environmental variables. 307 allows precise analysis and control of exposure to temperature, humidity, and CO2 levels. It is designed for use in the preparation of samples or for sample collection of liquid or gas, as well as for sample manipulation during analysis. EG&G 307 includes an injection port and a flash vaporizer chamber. The injection port is used to inject solids or liquid samples into the chamber, either in bulk or pre-dissolved in a compatible solvent. If the sample is liquid, flash vaporization occurs as an instant purge of the sample into gas form. The vaporizer is set to operate in "auto" or "manual" mode. In auto mode, the device takes in sample, vaporizes the sample and transfers it into the chamber with precise control. The sample is then blown out of the chamber and the parameters are checked to determine the molecular weight via the internal weighing mechanism. The internal weighing mechanism on 307 is a capacitive capsule loaded cell. This component measures the mass of sample molecules and has incremental resolution of 0.001 milligrams. It is accurate to within one milligram of the total weight. The machine is also able to print a hard copy of the reading. Furthermore, EG&G 307 can be operated manually or with a computerized control unit. 307 operates via a single phase power supply. It is plugged into a normal nongrounded electrical outlet and has an electronic heater and cooling system to allow extreme temperature modification. The external environmental chamber is also designed for both air and liquid cooling. In conclusion, EG&G 307 is a fully automated device for the precise measurement and manipulation of samples in the laboratory. It features a computerized control unit and an external environmental chamber with adjustable temperature, humidity and CO2 levels. It has an injection port and a flash vaporizer chamber for the introduction and vaporization of samples, and a capacitive capsule loaded cell to accurately measure the mass of sample molecules. Also, 307 is able to print a hard copy of the reading for further study. It is an efficient and reliable tool designed to make molecular weight determination simple and accurate.
