QED Laboratory Stuff

This is where we will store all information related to experimental work.

Lab Principles - good laboratory practice

The Ten Laboratory Commandments - QEDLabEtiquette :

1. Keep a comprehensive and comprehensible Lab Book How_to_keep_your_log_book.pdf
2. Make sure the lab is in a better condition when you leave than when you enter.
3. Don't leave the lab unattended at the wrong time
   
4. Do not leave broken or 'not-working-properly' stuff lying around
   
5. Fix it before it breaks
6. Keep the lab tidy
7. Record borrowed items in the lab borrow book
8. Security
9. Mobile phone number
10. Do not use measurement computers for internet surfing, watching TV, etc
