Laboratory furnacesare composed of a heating element connected to a sampling chamber and regulated by a digital controller.
What Is a Lab Furnace?
实验室炉执行几种常规功能，包括样品退火，烘烤，固化，溶剂去除和灭菌。尽管大多数炉子都是为安装在台式上安装而设计的，但是可以提供专业的自由式和步入式炉。
如何使用实验室炉？
Lab furnaces常用在材料科学、水treatment, environmental science, chemical, metal treatment, electronic, and agricultural biology industries.

A - Furnace Style and Design
（返回图表）
A1 - Ashing Furnace
玻璃炉determine the change in weight of a compound as one or more constituents are burned off. Ashing furnaces are used for the material analysis of coal, rubber, plastics, and grain. Specialty porcelain quartz crucibles accommodate up to 38 samples for high-volume ashing or incineration.
A2-盒炉
箱炉contain larger sample chambers than ashing and muffle furnaces for processing bulk samples, such as raw metals, plastics or electronics. Double-wall construction reduces exterior surface temperatures for operator protection and energy efficiency. Hinged side-mounted or top-mounted doors provide full-chamber access for quick loading and unloading of samples.
A3-炉子炉
Muffle furnacesare box furnaces equipped with ceramic fiber insulation to permit faster heating ramp rates than standard box furnaces. Muffle furnaces are used in laboratories for gravimetric analysis, sintering of small organics, quantitative analysis, and sample volatility studies.

A4 - Tube Furnace Design
Tube furnacesare designed for heating small samples in an inert atmosphere. Certain models include three-zone controls to support segmentation of the sampling chamber into three distinct temperature gradients for material testing. Tube furnaces are used for sample viscosity testing, calibration, thermal expansion, and crystal growing.
B - Maximum Lab Furnace Temperature
（返回图表）
Laboratory furnacesinclude a PLC controller to regulate temperatures from 100°C to the maximum temperature of the furnace, which ranges between 975°C and 1,700°C. Although lab ovens are also used for sample annealing, curing and baking, standard ovens do not maintain temperatures above 350°C.
C - Lab Furnace Controls and Programs

Thermo Fisher科学实验室炉包括安装在设备前面板上的积分PLC控制器，以方便访问和维护。积分控制器提供了几层方法和编程控制，以支持简单和高级协议。
C1-多程序炉
热费舍尔’s Lindberg/Blue M Box炉子包括能够存储多达25种不同程序的控制器，每个程序都有多个细分。
C2-多段炉
多段炉控制器allow for the segmentation of each program into individual ramp times (heating or cooling) and dwell times. Program patterns are defined by either time or rate and programs are repeatable for 999 cycles.
C3 - Furnace Setpoint
Simplified setpoint furnace controllerssupport protocols calling for a single-segment ramp to a specified temperature.
C4 - Single Program Furnace Controllers
热费舍尔Tube Furnaces with economical single program controllers, do not include a database of saved programs for quick retrieval. The single program, however, accommodates multiple segments for advanced heating protocols.
C5-单段炉控制器
单段炉控制器support procedures defining a single-segment ramp to a specified temperature, but may support multiple saved programs for different sample types.
D - Furnace Voltage

120伏连接适用于美国的标准实验室电源插座。
208-volt or 240-volt connections require less current (amperage) and smaller conductors than equipment designed to operate at 120-volt.
F - Special Furnace Features

F1 - Over-Temperature Protection
数字可调过的过度控制控制在控制器故障的情况下，一旦达到设定点，可以通过关闭电源来保护炉子和电气负载。
F2 -RS -232炉
Thermo Fisher Therlolyne台式式炉子炉包括RS-232端口，用于炉子和打印机或远程计算机之间的双向通信。
F3-炉流量计
热费舍尔Lindberg/Blue M LGO Box Furnacesinclude an adjustable gas flowmeter, mounted on the front panel for purging the sampling chamber with an inert gas, such as Nitrogen or Argon.
