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
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
磁力搅拌热夹contain 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
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 - 铝制热板
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.

E1 - 数字热板
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

G3 - 培养箱安全热板
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包括延长线，以允许用户在没有风险的化学照射的情况下操作热板。适用于安装在湿加工甲板上或通风罩内的单元，
