What is a Laboratory Hot Plate?
Laboratory hot platesconsist 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.
Stirring Hot Plate Styles, Components, and Types
搅拌器热点板块装备ped with anoverhead or magnetic stirring apparatusto mix the sample during the heating process, 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.

A1 - Hot Plate
标准温度控制热板do 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杆以预定义的速度（高达2500 rpm）旋转。磁力搅拌器不包括加热元件。
A3 - Stirring Hot Plate
搅拌热板contain both a stirring apparatus and heating element installed underneath the plate surface for even stirring as the sample heats. While stirring hot plates are more expensive than magnetic hot plate stirrersmagnetic stirrers or standard hot plates, they provide better heating uniformity for high-volume (over 500 ml) and highly-viscous samples.

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 platesare resistant to corrosion and withstand temperatures above 350°C. Ceramic’s white surface optimizes viewing of samples obscured by aluminum or steel plates. Ceramic tops are susceptible to heat shock from metal cylinders, so ceramic is an ideal choice for samples heated in glass beakers.
B3-聚丙烯热板
Polypropylene hot platesresist s harsh chemicals, acids and solvents, but do does not reach temperatures as high as ceramic or aluminum. Polypropylene hot plates are optimal for wet chemistry work involving solvents like methanol, acetonitrile and ethanol.
B4-不锈钢热板
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-热板温度
(back to chart)
标准热板的最高温度为250°C至350°C。
High-temperature hot plates, such asThermo Fisher’s Cimarec line, maintain temperatures up to 540°C for high-boiling point solvents.
孵化器安全热板are used with bacterial and mammalian cell cultures to achieve optimal growth conditions, such as 37°C or 45°C.
D - Hot Plate Voltage

120伏连接适用于美国的标准实验室电源插座。与旨在在120伏的设备相比，在欧洲大陆常见的240伏连接所需的电流（安培数）和较小的导体所需的速度更少。
E - Hot Plate Controllers and Heating Types
(back to chart)
E1 - Digital Hot Plates
Hot plates with digital controllersinclude 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 - Analog Hot Plates
Hot plates with analog controllersinclude 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-最大热板搅拌速度
(back to chart)
与顶部搅拌器一起使用的热板搅拌热板达到最高1200 rpm的速度，以混合样品和溶剂。为了进行粘性和大量样品，数字搅拌热板利用电磁体和搅拌条达到高达2500 rpm的速度。
G-针对应用程序的功能

G1 - Compact Hot Plates
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 - Remote-Controlled Hot Plates
Remote-controlled hot plates包括延长绳，使用户可以在不冒险的情况下操作热板。适合安装在湿加工甲板或烟雾罩中的单元的理想选择
