Laboratory Hot Plates and Magnetic Stirrer Features Comparison Chart
What is a Laboratory Hot Plate?
实验室热门板consist of a heating element installed underneath a plate surface, manufactured from conductive steel or plastic, connected to a digital or analog controller.
What is a Laboratory Hot Plate Used For?
Ubiquitous in clinical, production and research labs, hot plates are used to slowly and safely heat samples, reagents and chemicals without the dangers associated with the open flame of a Bunsen burner.
搅拌热板件，组件和类型
热板配有一个搅拌器overhead or magnetic stirring apparatus混合样品在加热过程中,ensuring more complete temperature uniformity. For operator protection, hot plates include several safeguards, including over-temperature prevention, audible and visual alarms, and non-sparking components for flammable or explosive samples.
A - 加热器搅拌板设计

A1 - Hot Plate
标准温度控制热板不包括用于在加热过程中进行样品混合的搅拌装置。比搅拌热板更经济，标准热搅拌器板是可靠的工作主管，需要最小的维护和重新校准程序。
A2 - Magnetic Stirrer with Hot Plates
Magnetic stirring hotplatescontain an electromagnet, installed underneath the plate surface, which produces a rotating magnetic field across the plate. The magnetic field causes a stirring bar, immersed within the sample, to spin at a predefined speed (up to 2,500 rpm). Magnetic stirrers do not include a heating element.
A3 - Stirring Hot Plate
Stirring hot plates含有安装在板表面下方的搅拌装置和加热元件，以甚至搅拌为样品热量。搅拌热板比磁性热板搅拌器或标准热板更昂贵，它们为高体积（超过500mL）和高粘性样品提供更好的加热均匀性。
B - Hot Plate Material

B1 - Aluminum Hot Plates
Aluminum hot plate surfaces provide better temperature uniformity than ceramic, polypropylene, or stainless steel. More durable and harder to crack, aluminum-top plates are optimal for high-throughput operations involving steel beakers.
B2 - Ceramic Hot Plates
Ceramic hot plates耐腐蚀性和耐高温以高于350°C。陶瓷的白色表面优化了由铝或钢板模糊的样品观察。陶瓷顶部容易受到金属缸的热震动，因此陶瓷是在玻璃烧杯中加热的样品的理想选择。
B3 - Polypropylene Hot Plates
聚丙烯热板抵抗刺激的化学品，酸和溶剂，但确实不会像陶瓷或铝一样达到温度。聚丙烯热板对于涉及甲醇，乙腈和乙醇等溶剂的湿化学工作是最佳的。
B4 - Stainless Steel Hot Plates
Stainless steel hot plates resists corrosion, most alcohols and ethers, and promotepromotes aseptic conditions. Stainless steel hot plates are optimal for ISO-grade cleanrooms, cGMP spaces and USP-compliant facilities.
C - Hot Plate Temperatures
(back to chart)
Standard hot plates carry a maximum temperature of 250°C to 350°C.
High-temperature hot plates, such asThermo Fisher的Cimarec线路, maintain temperatures up to 540°C for high-boiling point solvents.
Incubat要么-safe hot platesare used with bacterial and mammalian cell cultures to achieve optimal growth conditions, such as 37°C or 45°C.
D - 热板电压
(back to chart)
120-volt connections are suitable for standard laboratory power outlets in the United States. 240-volt connections, common in Mainland Europe, require less current (amperage) and smaller conductors than equipment designed to operate at 120-volt.
电子板控制器和加热类型
(back to chart)
E1 - Digital Hot Plates
带数字控制器的热板include on-board software for saving programs, PLC readouts to monitor temperature output, and up/down keys to quickly alter ramp rates. Advanced controllers include password protection, data export and over-temperature alarms.

E2 - 模拟热板
带模拟控制器的热板include dials to modify temperature set points and audible over-temperature alarms. More economical than digital hot plates, analog models require limited maintenance and re-calibration.
F - Maximum Hot Plate Stirring Speed
(back to chart)
Analog stirring hot plates with overhead stirrers reach speeds up to 1,200 rpm for mixing of samples and solvents. For viscous and high-volume samples, digital stirring hot plates utilize electromagnets and stirring bars to reach speeds up to 2,500 rpm.
G - Application-Specific Features
(back to chart)
G1 - 紧凑型热板
Optimal for crowded lab spaces and shared-use core facilities, small-footprint hot plates use limited benchtop space without sacrificing performance.
G2 - Explosion-Proof Hot Plates
Thermo Fisher’s explosion-proof hot plateis suitable for Class 1 location and Group D atmospheres housing explosive liquids and powders.
G3 - Incubator-Safe Hot Plates
Optimal for prokaryotic and eukaryotic cell culture work,incubator-safe hot platesmaintain temperatures ideal for cell line growth and resist moisture-based corrosion.
G4 - 遥控热板
Remote-controlled hot platesinclude extension cords to allow users to operate the hot plate without risking chemical exposure. Ideal for units installed on wet processing decks or within fume hoods,
