Modular holders chemistry labs

The base plate and the holders take standard small magnets (1.2 cm diameter; 2 mm thick)
The base plate is to be glued to a surface on to which the different holders can be placed.
The use of magnets allows for more than one type of configuration to be used on the same base plate surface, while at the same time preventing samples from sliding.
In the provided pictures, the design was used for sample conditioning on a Schlenk line.
The base plate was fixed to teflon screw caps by double sided tape.
