multiplex culture tube lid

The lab contest winners are featured on Teklab's Print My Lab project. Use ethanol to sterilize it before handling. You're told that nylon can print autoclavable parts, but I haven't tried this yet. http://www.teklalabs.org/print-my-lab-results/ Description: Sampling tubes from 12 to 36 at short intervals is crucial in some experiments, unfortunately the tube lids just friction fit on. Every tube has to be taken off uncapped and replaced with its cap again which must then also go into a separate place that's sterile. Mixing up caps between different tubes would lead to cross contamination so this entire process can take a lot of time that can't be spared in some cell culture tests. I solved the problem by connecting six tube lids in such a way that they just don't have enough friction to be taken off but are still loose enough not to cause too much strain, therefore it's possible to take off an entire row of tubes at once. This speeds up sampling time from minutes down to seconds and also stops cross contamination from happening which is vital for collecting valuable data without any problems. Print the cap holes upwards.
