One KF-40 vacuum bellows Three KF-40 quick clamps. Two KF-25 quick clamps.
HV Station High Vacuum Station	Structure	Mobile cart size:  600 (L) x 600 (W) x 700(H), mm Max. Loading:       600 Lbs on top Molecular pump control Panel:   LCD digital Inside:   Pfeiffer vacuum pump  Made in Germany Vacuum sensor is included
	Vacuum sensor	The vacuum sensor has a KF-25 connector. High vacuum gauge (measuring range 10^-8 mbar ~ 10^3 mbar)
	Control Panel	One button operation - the diaphragm pump and the turbomolecular pump will start after pressing the "start" button. System controlled spinning speed - the controller will control the speed of the turbine spinning up and down according to the vacuum level and leaking rate of the reaction chamber. Self-protection - the system will protect the pump from damage by overheating and overcurrent if the leaking rate of the reaction chamber is too high to achieve the high vacuum. LCD screen - double lines parameters checking interface make the working easier to be handled. Self-testing Spinning up Error report Voltmeter  Full speed

Warning Click here to learn the installation of a gas regulator	The tube furnaces with quartz tube are designed for use under vacuum and low pressure < 0.12 MPa (absolute pressure) Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator. The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
