VAPODEST 500 for precise Kjeldahl analyses in high-throughput labs

Specially developed for users in high-throughput laboratories, VAPODEST 500 performs Kjeldahl nitrogen determination as well as steam distillation of volatile substances. Efficiency, safety and conformity with standards are the features that matter most.

  • Efficient: Fully automated and process-optimized Kjeldahl analysis
  • Robust: Designed for high-throughput analyses and continuous operation
  • Fully integrated: Network-compatible data and process management

Combine VAPODEST 500 with the KJELDATHERM KT-L20s to use the most powerful complete solution on the market for Kjeldahl digestion and analysis.

Time-critical analysis and high throughput – no problem for the VAPODEST 500

In a high-throughput lab, each additional manual step costs you valuable time and reduces the reproducibility of your nitrogen analysis. So it’s good to know that VAPDOEST 500 is optimized for use in high-throughput laboratories.

Your benefits:
  • More samples analysed in less time because distillation and titration are performed simultaneously (online titration).
  • Reduced time to result because result calculation and data transfer are carried out automatically
  • Outstanding result precision compared to burettes because the high-precision microdosing pump and the software are perfectly matched
  • Peace of mind because you are guided through all steps of the process


Full network functionality – The C. Gerhardt Dashboard keeps you on top of things

VAPODEST 500 fits seamlessly into your processes. Use the full potential of the C. Gerhardt Dashboard:

  • Control devices in your network, such as printers, balances, LIMS and barcode scanners, via a single software solution.
  • Enter and evaluate sample data from anywhere, anytime.
  • Export your data directly to your LIMS system


Keep everything under control during nitrogen determination

For Kjeldahl analysis, there is no way around handling aggressive chemicals. However, the VAPODEST series keeps you safe at all times.

  • The clever and proven design protects you and your working environment from unintentional contact with hazardous substances.
  • The illuminated glass components give you a good view of the entire analysis process.
  • The self-diagnosis feature detects errors early and switches automatically to a safe mode.
  • The “Soft Start” feature ensures controlled reactions even when analysing reactive substances.
  • The filling level sensors fit on commercially available containers for chemicals, so there is no need for cumbersome decanting.


Well-prepared for your next audit

The requirements for standards-compliant Kjeldahl analysis and the corresponding data management are high. VAPODEST 500 supports you so there’s no need to worry about your next audit:

  • Individually configurable user rights
  • Automatic logs of all work steps
  • Tamper-proof data storage
  • Data management in compliance with DIN EN ISO, AOAC, EPA, ASTM, EU regulation, APHA, Ph. Eur. 2.5.33 Method 7, Procedure A.


Stay flexible with your spectrum of samples

If you work with strongly foaming samples or large volumes, it is often difficult to find the right sample container. C. Gerhardt offers sample containers from 250 ml to 1,200 ml and Kjeldahl flasks from 100 ml to 750 ml.


Uptime at predictable costs is a must

Determining nitrogen at high-throughput asks a lot of your Kjeldahl analyser. So it is good to know that its modular design simplifies maintenance. The working lives of the wearing parts are perfectly matched, making maintenance easy to plan and the costs predictable. Your benefit: your Kjeldahl system needs to be serviced only once a year, allowing undisturbed use for the entire year to follow.

Validated and chemical-resistant components, such as ceramic microdosing pumps and plastic distributor heads, let you benefit from low operating costs. A stand-by mode and the separately controllable cooling water supply keep costs down.
