eJournal Electronic Laboratory Notebook
Test documentation as it should be!

The electronic laboratory notebook eJournal is more than an adequate substitute for a paper-based laboratory notebook. eJournal automatically records all information gathered in the course of a test. In addition, it is also possible to consistently display and archive test regulations, material properties of the reactants and products, laboratory analyses and other information. This significantly increases productivity and prevents a loss of knowledge through employee turnover.

The trend towards electronic documents is becoming more and more evident. The American FDA (Food and Drug Administration) is pushing the deployment of electronic media within documentation. Digitally signed electronic documents in compliance with FDA 21 CFR Part 11 are legally equivalent to hand-signed paper documents. The increase of productivity in the research industry due to the change to an electronic system is estimated to be over 50%.

A computer-aided laboratory notebook offers significant advantages: read and write errors are eliminated, a search function enables a fast search for experiments and results. Tamper-proof filing with an electronic signature has been made possible. Test parameters, measurement data and evaluated results are presented in clear report sheets. 

The laboratory personnel receives support through additional functions (e.g. automated evaluation) and is relieved of particularly bothersome routine activities such as the noting of measurement values.

An electronic laboratory notebook is particularly a "must-have" if the laboratory process (synthesis laboratory, fermentation laboratory) has to run compliant with GLP (Good Laboratory Practice) standards or where a validated mode of operation is required.

Advantages of eJournal

  • A standardised way of working
  • Release of the lab personnel from routine activities
  • Avoidance of read and write errors
  • Filing free of manipulation
  • Easier retrieval of experiments
  • Promotes the paper-free laboratory
  • Individually configurable
  • Online evaluation and spreadsheets
  • Full-text search in individual or all PDF documents
  • Export of the test report as a PDF or RTF file


The relevant values, parameters and events and any possible text to be written and comments on a test are recorded and stored in the electronic laboratory notebook. It is also possible to automatically insert digital photographs which have been taken on an event-driven basis or according to schedule with the Multi-LabCam system during the test. The recorded data are shown on freely configurable report pages with tables, diagrams and value and text fields. As a result, this guarantees an optimal documentation of the test events at all times. Manual processing of the data is no longer required, thus eliminating one major source of errors. Unattended operation is now possible and night time and weekends are now available as times for experimenting. A multitude of tests can now be processed in a minimum of time.


A batch report with all values, events, operator interventions, value changes etc. is automatically established. Digital photographs, chemical formulas, laboratory analysis data, links to data files or websites, comments etc. can be easily inserted. eJournal is thus a major step in the direction of a paper-free laboratory. Authenticity and integrity of the information are ensured. The report can be adjusted to meet the special demands of your laboratory. It contains, among other things, a cover page with general information, a page with information on the reactants, products and system properties, a page with analysis values and report pages with the recorded measurement values, events, and comments. The layout of the report pages can be freely designed using the form generator. The recorded values are also graphically presented to enable a better overview. The laboratory notebook can be exported as a PDF or RTF file for further processing.


Evaluation and documentation of the experimental data are supported or fully automated. The recorded data can be automatically evaluated online using HiText and presented in tables or various diagrams in various forms, such as a set of curves, average values with minimum and maximum bars or standard deviations. Self-calculating tables are also possible.

Data Import and Export

There are various possibilities for a data exchange to third party software, such as

  • CSV files
  • Text files
  • Named pipe
  • Data interfaces

Comprehensive Documentation

A set of comprehensive synthesis recipes is essential for the clear execution of a reaction. It contains and respectively links all information required to make the reaction comprehensible. This includes information on the test construction, the recipe flow diagram, the data of the reactants and solvents and test parameters such as periods, quantities, temperatures and pressures. The material data and other parameters of the reactants and products can be called off from the LIMS database.

The storage of the synthesis recipes ensures the availability of all information required for a later repetition of a test.

Organisational, procedural and chemical information are also recorded in the eJournal to enable the remaining data to be precisely allocated.

eJournal structures the data in such a way that they can easily be retrieved with the help of the HiLIMS laboratory information management system and are available for further use. This ensures that new and proven synthesis recipes, including the knowledge of the synthesised substances, are not lost and available at all times. 

A single user license is also available for the modification of laboratory notebooks on an additional stand-alone workplace. The single user license does not require a LabVision® installation (see eJournal offline viewer).
