BINDER VDL 23 vacuum drying oven
The BINDER VDL 23 vacuum drying oven is specially designed to work safely and efficiently with flammable solvents at low temperatures and under vacuum. This model sets new standards for drying organic substances and preparing sensitive materials for downstream processes. Compared to conventional drying ovens, which are often only safe to a limited extent, this vacuum drying oven scores points with its ATEX-compliant design, which significantly minimizes explosion risks. Thanks to these features, the appliance offers a clear safety and efficiency advantage. Similarly robust solutions such as the [BINDER VDL 53 vacuum drying oven] also demonstrate how effective vacuum drying can be in complex laboratory applications, but the VDL 23 model is characterized by its more compact dimensions and equally high reliability.
Detailed device description
This device impresses with a wide range of features that are specially tailored to the requirements of laboratories and industrial facilities. It is operated intuitively via a modern touchscreen controller that visualizes both temperature and pressure in real time. Process parameters are automatically controlled by the programmable drying monitor and automatic ventilation takes place when the final criteria are reached. This ensures a reproducible and reliable drying process. As with other BINDER vacuum ovens, such as the [BINDER VD 53 vacuum drying oven], the walls are equipped with large heat conducting plates. These ensure optimum heat distribution and shorten the heat-up time.
Particular attention is paid to ATEX conformity in accordance with 2014/34/EU (EX II 2/3/- G IIB T3 Gb/Gc/- X). This increases safety when handling highly flammable substances and guarantees virtually risk-free operation. In addition, the integrated pressure monitoring system provides protection by only releasing the heating when the pressure is below 100 mbar. This protects both personnel and samples without unnecessarily complicating the process flow.Highlighted are the stable clamping inserts, which impress with a maximum load of 50 kg in total. The viewing window allows constant visual monitoring during the drying process without having to open the drying chamber. If required, various accessories such as stainless steel or aluminum inserts can be used to meet the requirements of a wide range of samples. The universal feed-through DN 16 supports external measuring systems, while an optional universal ventilation for inert gas or ambient air offers flexible application options.
Important technical data at a glance:
- Temperature range: +9 °C above ambient temperature to +110 °C
- Explosion protection according to ATEX (EX II 2/3/- G IIB T3 Gb/Gc/- X)
- Heating time to 100 °C: 110 minutes
- Leakage rate: approx. 0.01 bar/h
- Vacuum and temperature process: programmable via touchscreen
- Interior volume: 24 liters
- Nominal voltage: 200-230 V or 100-120 V at 50/60 Hz
- Energy consumption at 100 °C: 140 Wh/h
Other options, such as the APT-COM multi-management software and various analog outputs for pressure and temperature recording, can also facilitate integration into laboratory networks. If you need even more flexibility, you can even request a DN 40 universal feed-through to integrate additional measuring devices.
Certifications and standards
The device meets all the requirements of the ATEX Directive 2014/34/EU. This means that it is suitable for use in areas with potentially explosive atmospheres and can be used in environments where the handling of volatile, highly flammable substances is required. The safety glass pane and splinter protection complement this concept perfectly.
Typical areas of application
- Drying sensitive materials in pharmaceutical industry laboratories, for example active ingredients in powder form.
- Research facilities where organic solvents such as acetone, ethanol or diethyl ether are regularly used
- Forensic institutes that need to dry evidence materials gently and safely.
- Industrial Quality Control when testing heat-sensitive parts or electronic components.
FAQs
What is the maximum load of the slide-in units?
The maximum permissible total load is 50 kg, while each individual drawer can be loaded with up to 20 kg.
What safety functions are available
In addition to the ATEX-compliant design and the safety glass panel, the built-in pressure switch offers special protection. The heater is only released when the pressure is below 100 mbar.
How long does it take to heat up to 100 °C?
The heating time is around 110 minutes, whereby the large heat conducting plates promote even temperature distribution in the interior.
What options are available for process monitoring?
In addition to the integrated data logger, analog outputs for pressure and temperature can be installed. The APT-COM multi-management software is also available as an option to create comprehensive documentation.
For which voltage ranges is the device available?
The vacuum drying oven is available in two versions: 200-230 V and 100-120 V. Both models operate at 50/60 Hz and offer the same temperature range.
Conclusion
Thanks to its robust design, excellent heat transfer and ATEX-compliant safety features, this drying oven is ideal for applications involving flammable substances. It combines protection, ease of use and precision at the highest level. The range of applications can also be further expanded thanks to additional options. Anyone looking for a reliable and safe vacuum drying oven for sensitive laboratory substances will benefit from a well thought-out design and a wide range of functions that will also reliably cover future requirements.
