Product Manual Library
We do have a variety of Product Manuals at our disposal. Due to US Copyright law, manuals listed in our library are not for copy, sale and/or redistribution. These manuals are used by HiTechTrader.com to make sure that the parts, accessories, and actual instruments are compatible with our customers’ needs. They are also used to repair and maintain equipment. This compatibility is key when buying surplus laboratory or used analytical equipment. Specifications on equipment marketplaces, such as Ebay, can lack this crucial information. Our library allows us to answer customer “needs” questions (i.e.- “Can the software work on Windows XP, Windows 7, Windows 8, or Windows 10?”).
Make : Jasco
Model : 880-81 Back-Pressure Regulator
The Jasco Model 880-81 Back-Pressure Regulator is specially designed for the use in supercritical fluid extraction and supercritical fluid chromatography. Its operating principle is totally different from conventional regulators, and is based on high-speed flow switching. The model 880-81 has many advantages over conventional regulators as low dead-volume prevents fractions from being re-mixed each other, enabling sharp cut-off between fractions, the valve needle is vibrating and continuously forcing precipitate solutes to pass through the value path, allowing stable operation without blocking of the valve path, control pressure can be set simply by the digital switch in three-digit number, operating pressure is displayed on LED digital meter in three-digit number, and the valve body is thermostatted by a PID temperature controller. Contains 2 identical copies in stock.
