Liquid Dispensers and Receptacles

ENV-201A
Liquid Dispenser, Drop Type

This dispenser features a miniature solenoid-activated valve to dispense small drops or small quantities of water. The valve is activated by a 28 V DC output; however, the length of time the valve is on is controlled via an adjustable timer on the controller. The reservoir consists of a syringe tube which is easily removed from the luer fitting on the valve. The syringe tube is partially sealed, so that measurements of total volume can be made. This unit attaches to the top of the ENV-200R3M.

ENV-200R3M
Pellet/Liquid Drop Receptacle, Cup Type

This receptacle was designed for use with the ENV-201A liquid drop dispenser.  It also features a pellet tube on the back with a pellet guide, so that a single receptacle may be used for either pellets or liquid drops.

ENV-200R3AM
Cup Receptacle with Dual Liquid Pipes

This receptacle features two small stainless steel cups into which liquid may be pumped via 18 guage (custom sizes on request) stainless steel pipes.  Use with any syringe pump (see PHM-100) for precise delivery of a liquid reward.  This method is much more accurate than liquid valve style drop dispensers, and does not permit evaporation of the reservoir as with liquid dippers, which is ideal for alcohol studies.
