什么是实验室热板？
实验室热板consist of a heating element installed underneath a plate surface, manufactured from conductive steel or plastic, connected to a digital or analog controller.
实验室热板是用什么？
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.
搅拌热板样式，组件和类型
搅拌器热点板块装备ped with an开销或磁搅拌设备在加热过程中混合样品，以确保更完整的温度均匀性。为了保护操作员，热板包括几个保障措施，包括预防过度的预防，可聆听和视觉警报以及用于易燃或爆炸性样品的非屏蔽组件。
A-加热器搅拌板设计
(back to chart)
A1 - Hot Plate
Standard temperature control hot platesdo not include a stirring apparatus for sample mixing during the heating process. More economical than stirring hot plates, standard hot stirrer plates are reliable workhorses requiring minimal maintenance and re-calibration routines.
A2 - Magnetic Stirrer with Hot Plates
Magnetic stirring hotplates包含一个安装在板表面下方的电磁体，该电磁体在整个板上产生一个旋转的磁场。磁场会导致浸入样品中的搅拌棒以预定义的速度（高达2500 rpm）旋转。磁力搅拌器不包括加热元件。
A3-搅拌热板
Stirring hot plates既包含搅拌的设备，又包含安装在板表面下方的加热元件，即使在样品加热时搅拌。搅拌热板比磁性热板搅拌器或标准热板更昂贵，但它们为高体积（超过500毫升）和高粘性样品提供了更好的加热均匀性。
B - Hot Plate Material

B1 - Aluminum Hot Plates
铝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
陶瓷热板对腐蚀具有抗性，并承受350°C以上的温度。陶瓷的白色表面优化了对铝或钢板遮盖的样品的观看。陶瓷顶部容易受到金属气缸的热冲击，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S苛刻的化学物质，酸和溶剂，但不会达到陶瓷或铝的高温。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
不锈钢热板可抵抗腐蚀，大多数酒精和醚，以及促进脱氧物质的无菌条件。不锈钢热板是ISO级洁净室，CGMP空间和USP兼容设施的最佳选择。
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系列, maintain temperatures up to 540°C for high-boiling point solvents.
Incubator-safe hot platesare used with bacterial and mammalian cell cultures to achieve optimal growth conditions, such as 37°C or 45°C.
D - Hot Plate Voltage
(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.
E - Hot Plate Controllers and Heating Types
(back to chart)
E1 - Digital Hot Plates
带有数字控制器的热板包括用于保存程序的板载软件，PLC读数以监视温度输出，以及向上/向下键，以快速更改坡道费率。高级控制器包括密码保护，数据导出和过度温度警报。
Buy Digital Hot Plates and Stirrers
E2 - Analog Hot Plates
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-紧凑的热板
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的防爆热板is suitable for Class 1 location and Group D atmospheres housing explosive liquids and powders.
G3 - Incubator-Safe Hot Plates
对原核和真核细胞培养工作的最佳incubator-safe hot platesmaintain temperatures ideal for cell line growth and resist moisture-based corrosion.
G4-遥控热板
遥控的热板include 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,
