Working with molecular biology, you need imagination, unless you got a microscopic eyes that can zoom into molecules. Here are some tools we using.
A spectrometry, to check on the concentration of bacterial cells, protein, as well as DNA by the reflextion of light.
An Autoclaving machine, heat up to 121C for 15mins, 15bar, in order to sterilize culture media, keep our tools from contamination by microbes.
Not what u want? run again then, u just wasted another 60minutes.
There are a lot other useful stuff for molecular biology such as SDS P.A.G.E for protein analysis, crystallization wells and others.
