Liquid delivery > Pressure switches - Injectors and Spritzers, for automated perfusion and liquid delivery

8-Channel pressure switch, PS-V8P

This small manifold can deliver pressure to eight independent outputs - channels. If connected to sealed containers, small volume manifolds or cylinders, the pressure switch can deliver solutions to any custom chamber or fluidics device (no syringe pump or gravity driven perfusion is required). Can be used with any volume containers, including transfer bottles.  Can be also used with zero-dead volume manifolds to deliver solutions into small chambers and dishes. Requires a pressure pump and the valve controller. The controller can be programmed to deliver solution sequences and for continuous periodic solution replenishment. The switch is rated up to 150 PSI input pressure. It has a secondary threaded input port for the balance pressure to prevent back-flow. Dimensions: 5x2x2in. If purchased together with PC-16 valve controller, the switch will ship with free SVDS1 small volume manifold. Click on image to enlarge.

8-Channel Programmable Pressure Pico-Injector - Spritzer, UC-8

For use with pipettes, thin tubing, and small volume delivery systems. Generates pressure up to 15PSI with stability (does not require an external source of pressure, but can be modified to work with external pressure sources up to 300PSI). The controller regulates output pressure to provide defined solution flow to your sample. Prevents flow blockage by bubbles inside solutions. Eight channels with independent timers with 1ms resolution that can be programmed using touch screen. Includes remote control for easy operation. For 4-channel spritzers with independent channel pressure control, consider UC-4 model.

1-Channel Programmable Pressure Pico-Injector - Spritzer, UC-1

For use with pipettes, thin tubing, and small volume delivery systems. Generates pressure up to 15PSI with stability (does not require an external source of pressure, but can be modified to work with external pressure sources up to 300PSI). The controller regulates output pressure to provide defined solution flow to your sample. Prevents flow blockage by bubbles inside solutions. Built-in programmable timers with 1ms resolution. Includes remote control for easy operation.

Programmable 8-Channel liquid delivery system, PS-8P

In addition to 8-channel pressure switch PS-V8P, this setup includes 16-channel programmable valve controller with built-in 0-15PSI pressure controller-pump, adjustable stand SH-1A, small volume manifolds SVDS1 and SVDS2, and sets of pressure cylinders PC-10 and PC-50 (x8 each), connecting tubing and fitting. Can deliver solutions to any custom chamber or fluidics device (no syringe pump or gravity driven perfusion is required). Can be also used with zero-dead volume manifolds to deliver solutions into small chambers and dishes.

The controller opens valves through
  • manual buttons
  • wireless remote control
  • optically isolated digital or TTL signals generated by a computer or other equipment
  • analog signal
  • RS232 port (or USB connection) for software control

The controller can operate in AUTO Memory mode, to program timers and channels sequences for precise timing during manual operation;

INHIBIT mode with manual and external controls allows you to switch all channels OFF at once, if required. 

The controller has an option for valves control by Binary Encoding using only 2-4 digital inputs, in case if a limited number of digital outputs are available in your system. The RS232 port allows automation of solution switching and integration with data acquisition and imaging systems.

SET output is used to switch an outflow unit ON automatically every time perfusion is ON.

RS232 port allows software control by any imaging or data acquisition setup. Can be upgraded to USB/RS232 adapter. 

Comes with an external 120/220V power supply.

Small Volume Delivery System with pressure switch, SVDS2-P

This is the same SVDS2 manifold for 15ml tubes with incorporated pressure switch, which is controlled by PC-16 controller. It allows you to connect tubes directly to the manifolds without using valves. Ideal for use with custom fluidics devices and zero-dead volume manifolds that do not have back-flow. The system has a secondary input port for the balance pressure to prevent back-flow. The valve controller can be programmed using built-in timers to generate solution sequences. Requires pressurized gas to deliver the solutions.

The system comes with all necessary tubing and fitting to connect to a pressure source and to the manifolds or sample chambers. The small size allows to position solutions near your sample. Comes with X-block to attach onto a standard 0.5 in. stand. Includes replaceable plastic tubes x8 15ml, PTFE tubing, fitting and tubing to connect to a pressure source, and cable to connect to the valve controller. Click on image to enlarge.
