Labbox hotplate with digital display, Onilab HP550-S, EU cable
The Labbox hotplate with digital display is specially designed for demanding laboratory applications where precise and constant temperature control is crucial. Whether for the synthesis of chemical compounds or sample preparation in research facilities - thanks to precise temperature control and a reliable safety circuit, this model outperforms many alternatives available on the market. The robust design and integrated safety mechanisms make it ideal for continuous use in laboratories, universities and industrial research departments.
Precise temperature control for laboratory use
With its square Ceran heating plate measuring 184 x 184 mm, this heating plate offers even heat distribution up to a maximum temperature of 550 °C. The temperature can be adjusted in 5 °C steps, allowing precise control according to requirements. The digital display shows the set and actual temperature with an accuracy of ±1 °C, allowing users to keep a precise eye on the current temperature at all times.
The Pt1000 temperature probe included in the scope of delivery is particularly practical and allows external temperature control. This allows the core temperature of the sample to be measured instead of relying solely on the heating plate surface. This direct measurement not only increases accuracy, but also reduces temperature fluctuations when working with temperature-sensitive substances.
The integrated safety circuit detects overheating and automatically switches off the heating function as soon as the plate exceeds 580 °C. In addition, a "HOT" display clearly indicates that the plate still has residual heat, even if it has already been switched off. This reduces the risk of burns and makes it easier to use the hotplate safely in everyday laboratory work.

Concrete application examples
- Chemical syntheses: When heating reaction batches in flasks, beakers or reactors, the even distribution of heat ensures a controlled reaction. Substances such as ethanol or toluene can be heated safely and evenly
.
- Sample preparation: For laboratory analyses such as drying, evaporation or melting point determination, the exact temperature plays an essential role in achieving reproducible results.
- Pharmacological research: When producing or modifying pharmaceutical samples, researchers benefit from controlled heating, for example when developing new active ingredients.
- Biochemical experiments: In molecular biology or biotechnology in particular, defined temperatures are often required to allow enzyme reactions to take place in a controlled manner or to denature proteins.
Thanks to its versatility, compact format and robust design, this device is the ideal choice for research and development laboratories, quality control departments and educational institutes.
FAQs
How safe is operation at high temperatures?
The heating plate is equipped with a separate safety circuit that switches on automatically as soon as the core temperature rises above 580 °C. This prevents overheating and the appliance switches off early to prevent damage or accidents.
Do I need additional accessories?
The stand rod for the temperature sensor (STIH-A04-001) is not included in the scope of delivery. For special laboratory applications where an exact measuring point needs to be fixed, it is recommended to purchase this stand rod separately so that the probe can be optimally positioned.
How can the exact temperature in the sample be determined?
Thanks to the Pt1000 temperature probe included in the scope of delivery, the temperature can be measured directly in the substance to be heated. This ensures reliable and precise temperature control of the medium, which is particularly useful for temperature-sensitive applications.
Is the heating plate splash-proof?
The housing has protection class IP21 and therefore protects against dripping water. While care is still required in everyday use, this standard significantly increases operational safety in a normal laboratory environment.
Which substances can be heated
In principle, temperature control is designed for a wide range of substances, such as organic solvents, aqueous samples or reagents in chemical syntheses. It is important to observe the general safety regulations in the laboratory, especially for highly flammable or reactive substances.
What is the maximum sample quantity?
The maximum sample quantity depends on the container used and the heat capacity of the substance. As the heating plate has a nominal output of 1000 W, it is suitable for medium sample volumes. For very large volumes or highly exothermic reactions, it is advisable to choose a device with a higher power reserve.
Does the manufacturer offer a guarantee?
There is a two-year warranty, which contributes to reliable, long-lasting operation if the hotplate is used and maintained correctly.
