Dual syringe holder for a Harvard syringe pump

The standard Harvard syringe pump accommodates a single syringe.
Rather than buying another pump to fit 2 syringes, use these adapter pieces.

Front piece sits on the syringe bed, beneath the syringe clamp, holding the syringes in place.
Back piece connects to the driver to deliver force to the two syringes.

*Rate of infusion cannot be controlled independently but the volumes can, by staggering the position of the syringes.
