3D model description

(the URL is missing the - at the end for the hyperlink)

An open source volumetric peristaltic pump developed as a low cost alternative to expensive laboratory grade volumetric pumps and peristaltic pumps. This device was developed during my analytical chemistry undergraduate research. It features volumetric and continuous delivery modes with accuracy of less than 1% error when delivering a volume if correctly calibrated.

This pump features:
continuous & volumetric delivery modes
variable flow rate 0.5 - 24mL/min
direction control
blowout for operation with a micropipette tips to reduce error between deliveries
interface with LabView over serial port

Most of the parts for this project can be printed without support, however there are 4 parts that require support for printing.
These are:
pump front
pump back
tubing clamp
tensioning fixture

The operation of this device uses a rotary encoder to select items on a menu. Rotation of the encoder will change between different modes and settings. Pressing the button selects the item, and rotating the encoder will change the value or state of that item.

More detailed writeup on operation will be added later.
