1200C Laboratory Tube Furnace With Vacuum Flanges And Quartz Tube 60mm

Product Overview

PT D60/400/12 is a single zone split atmosphere controlled laboratory tubular furnace with HRE heating wire up to 1200℃. Equips a OD60mm quartz glass tube, 304SS fast open sealing flange with needle valves and gauges. The single zone lab tubular furnace is controlled by a high-precision digital controller, a microprocessor-based self-tuning PID controller, which provides 30 segments of programmability, with accuracy of +/-1°C and no overshoot. Our laboratory tube furnaces specially equip a single-channel gas supplying device, it can be purged with inert gases such as argon, nitrogen, helium, synthetic air, oxygen and a small amount of diluted nitrogen or H2 in nitrogen.

Product Details

1200°C Single zone Laboratory tubular furnace with gas supplying device

• The 1200°C atmosphere controlled single zone laboratory tubuar furnace is mainly composed of five parts: furnace body, furnace tube, flange sealing accessories, gas supplying system and temperature control system. The furnace outer steel shell is processed with pickling and phosphating, environment powder coating on the surface, corrosion and oxidation resistance, built-in cooling fan, surface temperature Rt+45℃
• Exquisite appearance, ISO, CE compliance

1200°C Single Zone Laboratory tubular furnace chamber​ 

• The tubular furnace is made of two semicircular ceramic fiber materials, vacuum filtered, and tightly coupled in one piece. Embedded HRE alloy resistance wire with temperature up to 1200℃, surround convection heating, uniform temperature field
• The heating zone length is 400mm and can be adapted to 40-80mm quartz tubes. The processing tube is made of high-purity transparent quartz tube, with a temperature resistance of 1200°C. The critical part of the heating zone inside the furnace tube is equipped with the ceramic tube plug, which can effectively prevent heat from escaping and reduce heat loss
• N type thermocouple locates on the top of the chamber centre

Quick opening flange, furnace tube supports, 1/4" pagoda gas nozzle

• Equipped with SS304 quick-opening flange accessories for materials fast loading and unloading, sealed with high-temperature resistant fluorine rubber sealing rings
• The air inlet and outlet adopts G1/4-inch pagoda air nozzle, which can be connected to a PTFE pipe with an outer diameter of 8mm. Max vacuum can reach 10*-7torr
• Equipped with adjustable flange brackets to ensure safe and stable operation of the furnace tube

Single channel gas supplying device

• The 1200C-1700C laboratory tubular furnaces are all equipped with a single-channel gas supply device
• Double ferrule joints; gas float flowmeter, the flow rate is adjustable ranges 60-600ml/min
• Available gases: N2, Ar, H2, CO etc.

      NOTE:When filling reducing gas, check valves, one-way valves, exhaust gas treatment systems, etc

Control panel for 1200°C atmosphere controlled lab tubular furnace

• Integrated design with temp controller, Ammeter, voltmeter, function buttons on panel

Technical Specifications

Application Notes

• Quartz tube pressure should be lower 0.02MPa
• Gas source should equip the pressure reducing valve
• Before filling reduction gases like H2, should pump the air out of the tube
• When filling gases from gas inlet in the tube, should make sure the gas outlet valve open
