What are laboratory hotplates used for? Hotplates are true all-rounders! They are used to heat substances in containers such as beakers, flasks, or test tubes. The heated substances are then used for various applications, such as chemical synthesis and sample preparation. But hotplates can do much more! They evaporate solvents, melt solids, and maintain the temperature of a reaction or process.
Be sure to contact your häberle expert if you want to evaporate solvents in a solution! He or she can help you make the right decision.
Hotplates for chemicals are used in scientific research in various fields, such as biology, chemistry, and materials science. In biology, these plates are true all-rounders! They are often used for cell cultivation, sterilizing equipment, and preparing samples for analysis. In chemistry, hotplates are essential for chemical synthesis, cleaning substances, and conducting chemical reactions.
Hotplates are indispensable in materials science
They are used for processing and testing materials, such as melting metals for casting or heating ceramics to high temperatures.
However, hotplates are not only a blessing in research but are also used in various industrial sectors. They are used for melting or heating materials, drying and curing coatings, and preheating parts for manufacturing. But that's not all, because hotplates can also be used in product quality control and testing. Laboratory hotplates are essential for many scientific and industrial applications. Their versatility and controllability make them an absolute highlight and an indispensable part of every laboratory and production facility.
Three types of hotplate surfaces There are three fantastic main types of surfaces used for laboratory hotplates: ceramic, aluminum, and stainless steel. Each surface has its amazing features and is best suited for specific applications.
Ceramic hotplates:
Ceramic surfaces are extremely popular for laboratory hotplates due to their excellent corrosion resistance, high temperature stability, and uniform heating. Ceramic hotplates are true all-rounders! They quickly reach high temperatures, which leads to the evaporation of solvents or boiling of low-boiling liquids. However, this is also a small risk because solvents can splash, which can be dangerous. But hey, that's part of the deal when you're on fire and flame about it! But don't worry, because we have the perfect solution for you! Simply use suitable laboratory equipment such as a heating mantle or reflux system when heating samples with low boiling points or evaporating solvents. Or use one of our high-quality ceramic hotplates with a precise temperature controller that allows you to easily prevent overheating of the sample.
Aluminum hotplates are a great cost-effective alternative to ceramic hotplates. They are super lightweight and have excellent thermal conductivity, making them perfect for applications that require rapid heating or cooling.
Stainless steel hotplates are also a great choice. Stainless steel surfaces are extremely durable and corrosion-resistant. They are perfect for rough laboratory environments because they are super easy to clean and maintain. And they are also ideal for applications that require high temperature stability and uniform heating. Ceramic surfaces are a real all-rounder! They are super resistant to corrosion and high temperatures. No wonder these plates are so popular in scientific research, healthcare, and industrial applications.
Ceramic hotplates are perfect for low to medium temperature applications. For example, they are great for evaporating solvents or heating samples with low boiling points. Ceramic hotplates are also ideal for applications where a uniform heating surface is required to ensure the consistency of the experiment or process. And the best part: They are often used in biochemistry, organic synthesis, and medical research!
But that's not all, because ceramic hotplates also score with these advantages: This means they can withstand sudden temperature fluctuations effortlessly without breaking or splintering - a clear advantage!
Thanks to their uniform heating surface, you can be sure that all samples are heated evenly and consistently.
Chemical resistance - another highlight!
Ceramic surfaces are chemically inert and generally do not react with heated substances. This means that contamination of samples in the laboratory is reliably prevented.
Aluminum hotplates Aluminum hotplates feature a flat aluminum surface that heats up when electric current flows through it. This works similar to ceramic hotplates. These plates are at home in various industries, such as food processing, materials science, and manufacturing.
To the products The benefits of aluminum hotplates include:
Excellent thermal conductivity - Aluminum is an excellent conductor of heat and ideal for applications that require rapid heating or cooling.
Lightweight and portable - Aluminum hotplates are lightweight and portable. This property makes them ideal for use in the field or remote locations.
Aluminum hotplates are super easy to clean because their surface is generally smooth and easy to clean. This is really convenient because it prevents contamination and maintenance is super easy.
Stainless steel hotplates are also really cool because they have a flat stainless steel surface that heats up when electric current flows through it. Their surface is extremely resistant and corrosion-resistant, making them suitable for various scientific, medical, and industrial applications. They are also suitable for applications in chemical engineering, materials science, and metallurgical research.
Stainless steel hotplates offer a variety of advantages!
Durability: Stainless steel hotplates are extremely durable and corrosion-resistant. They are therefore ideal for long-term use.
High-temperature suitability: Stainless steel surfaces can withstand high temperatures. They are used for applications requiring high heat.
Stainless steel surfaces are not only easy to clean and maintain but also extremely hygienic. The risk of contamination is minimized and maintenance is easy.
Round vs. square hotplates
Round and square hotplates are two absolutely useful laboratory heating devices, each suitable for certain applications. Here are some factors to consider when deciding on a specific type of hotplate.
Shape of glassware: If you mainly use glassware with a round bottom, such as round-bottom flasks or test tubes, a hotplate with a round surface is perfect because it perfectly matches the curved shape.
On the other hand, if you frequently use square or rectangular glassware, such as crystallization dishes, a square hotplate may be the perfect choice because the flat surface perfectly matches the shape of the glassware.
The square shape is just perfect for anyone conducting sensitive experiments or working with hazardous materials.
Heat distribution:
Round hotplates distribute heat more evenly over the round surface, while square hotplates may have hot spots due to uneven heat distribution. This is an important point for conducting temperature-sensitive experiments.
Advantages and disadvantages of round hotplates
They are suitable for various shapes and sizes of glassware, including glassware with a round bottom.
They distribute heat evenly over the round surface, which is advantageous for conducting temperature-sensitive experiments.
They are easy to use and set up.
Square hotplates offer a variety of advantages! They are perfect for experiments requiring stirring or mixing. The flat sides of the heating surface are super easy to clean and maintain. And the shape is perfect for square or rectangular glassware.
But even though there are some disadvantages, the advantages outweigh them by far! Uneven heat distribution on the surface can create hot spots. But there's no need to worry because these spots can be easily avoided by pre-heating the hotplate before use.
Another disadvantage is that they may not be suitable for glassware with a round bottom. But there's a solution for that too: Simply use a pad to protect the hotplate.
And even though it may be a bit more difficult to use them with different sizes of glassware, there's no need to worry. Because there's the practical adjustment option.
Heating mantles are a brilliant invention!
They are glass-silk-insulated heaters and serve to heat various glass vessels. This allows you to maintain media at processing temperature or increase to a desired temperature. A heating mantle can have multiple heating zones, which can be independently switched and controlled depending on the design. This ensures uniform heat transfer and gentle treatment of laboratory glassware. The thermal insulation between the heating element and the outer shell reliably
