I have used LabCollector since 2010 for samples like DNA, RNA, tissues, primers, bacteria, cells, embryos and enzymes.  I have followed all the nice evolutions of this database. I just have one piece of advice to give:

Don’t just think about where  to store your samples, but also where to find them in the future.

If you use the database and the electronic lab notebook (ELN), you will have a very effective tool to follow your experiments,  the samples generated and where they are stored.
I really appreciate the customer service at LabCollector because they always respond to my specific requests and try to find solutions to my problems. LabCollector is a database adapted to its clients.
