AG Hauck - LabWiki
Welcome to the Hauck's LabWiki
This is the LabWiki – your central reference for all methods, rules, and protocols in our laboratory!
This wiki is designed to help you work safely, efficiently, and reliably. Here you will find guides on various work techniques, important safety regulations, and documentation on equipment and materials.
The data and protocols have been curated and carefully prepared over a long period of time. Nevertheless, there may still be errors in a few areas. Please let us know in the discussion section of the respective article.
Knowledge grows when shared. That's why we appreciate it when you contribute your knowledge here and help us continue developing it.

💡 Pro Tips
Before printing:
- Check print preview: Is everything fully visible?
- Consider page count: Split long protocols?
- Images/Tables: Are they displayed correctly?
For large tables:
- Choose landscape orientation for wide pipetting schemes
- Reduce scale to 70-80%
- Check page breaks in preview
Save ink/toner:
- Disable background graphics
- Use draft mode for internal protocols
- Black & white for color printers
🔧 Troubleshooting
Text gets cut off
- Reduce scale (85-90%)
- Set margins to "narrow"
- Use landscape for wide content
Page too long
- Check page breaks in preview
- Use "Print selection" for specific sections
- Create multiple PDFs for different sections
Images/formulas missing
- Enable "Print background graphics"
- Refresh browser before printing
- Take screenshot as alternative
💡 Tip: For important protocols, always save as PDF first, then print!
