Parametric dual motor syringe with enhanced design - Imperial College London

//UPDATED 21/9/14: Syringe holder adjusted to make motor holder more rigid and to move the syringe body lip closer to the piston lip.//

A single motor syringe was tried and tested, we found that it was inadequate for high accuracy and precision situations. Pulling and pushing assymetrically adjacent to the syringe body caused flexing and strain in the piston holder. This design provides two motors pulling/pushing either side of the syringe, to eliminate flexing and increase reliability and power available.
We have successfully used this with glass syringes to reduce non specific adsorption of reagents to the syringe wall.
The design is mostly parametric and we be further modified to include more relevant parameters of interest to the user.
