Government College Of Engineering And Textile Technology Tender

Thermo Gravimetric Analyzer (TGA) with following specifications • Modular design with interchangeable furnaces – TGA system should be easily reconfigured to a STA model, for greater flexibility and versatility. • Easy changeable Sensor without Service interaction – Sensor should be easily removed, replaced, and cleaned by customer – no service required. • Compact system with smallest footprint - the instrument should have a footprint less than 38 cm square. • Should include mass flow controller - an integrated mass flow controller for monitoring and controlling purge flow rates must be included as standard. • Control on both sample and balance purge. • Intuitive Touchscreen - Touch interface must simplify instrument operation, significantly enhancing productivity. • Should include Software suite which is easy to use and feature rich for maximum application flexibility. • Designed for Hyphenation – should be designed to be easily linked to other instruments like FTIR / GCMS (Hyphenation) with manual or automated loading. • Balance to be of top-loading design to allow ease of sample loading and operation. • The furnace must be made of a material which is corrosion resistant. • The instrument should be designed so that the furnace and balance are isolated from operators. • Must be able to heat at up to 300°C/min controlled and 450°C/min ballistic. • The temperature range needs to cover 15°C to 1100°C. • The balance should be protected from the reactive sample purge gas as well as materials evolved by the sample. • Temperature precision needs to be 0.6 °C • Calibrating via either melting or curie points • Balance measurement range up to 1500mg. • Balance Accuracy to be better than 0.005% of total sample mass. • Balance Precision ± 0.005% • The following cooling time is necessary: 1000 to 30 °C in less than 20 minutes. • Must have an inert cooling gas – for faster cooling of your gas choice. • Comprehensive accessory kit to be included as standard. • Atmosphere can be static or dynamic, including nitrogen, helium, carbon dioxide, air, oxygen, argon or other inert or active gases over full temp range. • Small furnace improved balance housing design should be there for reduced gas consumption. Local accessories: Suitable PC, Printer, UPS and necessary Gas Cylinders with Double Stage regulators should also to be included with the machine and the rate quoted accordingly with specifications.
