Cooper Union 2014 iGEM 

== Test Tube Roller ==

(picture)



== Introduction ==

The test tube roller is an open source lab equipment design. This design was created by Karlin Yeh and Wilfrido Castillo and a version of it is in the Cooper Union. This design is made from cardboard, .125" acrylic, a few electronic components and a DC motor. 

== Build ==

Parts

The following are needed to build the roller:

- .125" acrylic sheet
-DC Motor
-Power adapter

A 12V wall wart was used for this but most appropriate power sources can be used.

-Power switch
-Transistor

Both a power switch and transistor are optional and can be used to regulate the power and speed of the motor.

-#8-32 screws, jam nuts, and locknuts


Plans

(Need to post the dxf files and sldprt) The mounting holes and 3-d printed hub may need to be modified based on the DC motor being used.


Assembly

The acrylic pieces are assembled to make the frame with screws.

The motor is mounted to the front piece using screws.

A transistor can be soldered on the wall wart to control the speed.

The hub and spinner plate are screwed on to the motor.

The test tubes slip fit onto the spinner plate. 


Final Assembly

(pictures of the roller with test tubes)

The design was mainly based around the DC motor since it was the only one that could be used at the moment. Future designs can be modified to fit other DC motor's.
