OHAUS monoblock heating block
These flexible heating blocks are designed to support laboratory applications where constant and precise temperature control is required. Whether for incubating samples, performing immunoassays or denaturing nucleic acids, users benefit from high temperature uniformity and stability with this system. This allows reactions to be carried out reliably and reproducible results to be achieved. Compared to similar devices on the market, these monoblocks impress with their robust design, versatile configuration options and user-friendly handling for everyday laboratory use.
Versatile features and technical details
The heating blocks are available in both digital and analog versions. Digital models enable precise temperature control and fine adjustment for demanding applications. Analog-controlled devices, on the other hand, offer solid performance at an attractive price-performance ratio. Both versions are equipped with an interchangeable module block that allows up to 40 configurations and can be changed in seconds without tools. This allows a wide variety of tubes to be accommodated, creating a high degree of flexibility for laboratories with varying application requirements.
Overview of important technical data:
- Choice of digital (HB1DG) or analog (HB1AL) control
- Temperature range (digital): 5 °C above room temperature up to 120 °C
- Temperature range (analog): 5 °C above RT to 100 °C (low range) or 75 °C to 150 °C (high range)
- Stability: ±0.2 °C (digital) or ±1.5 °C (analog)
- Homogeneity: ±0.2 °C at 37 °C (digital) or ±0.4 °C at 37 °C (analog)
- Heat-up time: approx. 16 minutes
- Safety certification: CE and TÜV tested
These monoblocks have a painted steel housing and therefore offer a durable and hard-wearing construction. The digital versions also impress with a practical touchpad, whose easy-to-read LED display shows both the temperature and time. Here you can switch between different setpoints in a matter of seconds, which supports efficient operation. The digital versions also offer an integrated timer function from one second to 9999 minutes. Another plus point is the single-point calibration function, which can be used to adjust the device's display to known external standards. The analog systems are controlled using two controllers and are ideal when a rough temperature adjustment is sufficient and an exact timer is not required.
A key feature is the tight fit between the sample tube and block, which maximizes heat retention. This results in a rapid heat-up time and homogeneous temperature distribution, which is particularly important for sensitive applications such as enzyme reactions. To provide users with even better protection against uncontrolled temperature peaks, the digital models have integrated overload protection (approx. 10 °C above the desired setpoint).
Certifications and standards
In order to meet the high requirements of professional laboratory environments, these heating blocks comply with CE and TÜV standards, among others. Users can therefore rely on tested material and safety standards for all routine and special applications. The robust design and corrosion-resistant paint additionally increase operational safety in daily use.
Application examples
-
Microbiological incubation
The flexibly adjustable heating blocks are suitable for the growth of bacterial or yeast cultures. Thanks to precise temperature stability, enzymes and microorganisms can be cultivated under optimal conditions, for example when culture media or agar preparations need to be heated to a specific temperature.
-
Enzyme reactions in molecular biology
Whether restriction digestion, ligation or PCR preparation: with their precise temperature control, the blocks are predestined for a wide range of enzymatic processes. This allows proteases, nucleases or polymerases to be incubated under ideal conditions in order to carry out reactions faster and more reliably.
-
Immunoassays in the diagnostics laboratory
For procedures such as ELISA or Western blot, the samples or reagents in tubes can be quickly brought to the required temperature. The digital version with timer function also ensures reliable compliance with defined incubation times
.
-
Research into protein and nucleic acid interactions
If complex structures are being investigated, high-precision temperature control is crucial. The monoblocks offer uniform heat distribution, which is helpful for denaturation steps and hybridizations, for example when melting DNA fragments or heating protein solutions.
FAQs
How easy is it to calibrate the digital models?
The digital heating blocks have a single-point calibration function that can be used to adjust the internal temperature display to known external standards. This keeps the temperature control accurate and reliable.
Can you use different sample sizes?
Yes, thanks to the large number of available module blocks, different tube sizes can be adapted. Each block can also be changed without tools.
Are the devices suitable for continuous operation?
The robust design made of painted steel enables long-term use in everyday laboratory work. At the same time, built-in safety functions - such as overload protection on digital models - ensure safe operation at all times.
Do I need specific accessories for the analog versions?
The analog models can be combined with an external thermometer or a separate temperature display to determine the exact temperature setpoint. This improves accuracy and is recommended for many applications.
Conclusion
These heating blocks offer a successful combination of precision, robust construction and uncomplicated operation. Whether in research, industry or routine analysis: Thanks to the interchangeable module block and versatile temperature ranges, they are equipped for a wide range of applications. Users benefit from high temperature stability, fast heat-up times and various safety features. If you are looking for a reliable heating system, this solution provides you with powerful and durable equipment for professional laboratory use.
