Scientifica Programmable Perfusion System (PPS)

Scientifica’s PPS combines full computer control of ten pinch valves and a high performance peristaltic pump, allowing the user to conduct fully automated and highly accurate perfusion. The PPS is contained within electronically isolated stainless steel housing with a magnetic base for simple and stable mounting.

Applications:

Drug delivery

Electrophysiology

If you are considering the PPS, you might consider the Slice Recording Chamber Kit or SliceMate temperature controlled tissue chamber.

Hands free control

  • Control the PPS on your PC by using Scientifica's LinLab software, control pinch valves and flow rate "hands free".

Custom protocols

  • Sequences can be programmed, saved and recalled to replicate difficult sequences, or help speed up time consuming routines such as cleaning and repeating assays.

TTL output

  • Timing of perfused stimuli can be precisely and automatically linked to cell responses, thanks to integration into pClamp and other DAQ systems.

Ten Channel Perfusion

  • Transfer up to eight solutions to your sample with the 8 inflow and 2 outflow pinch valves which smoothly control and match the rate in and out of your bath. A 4 roller peristaltic pump is also available.

Ultra-low noise electronics

  • Place the PPS close to your experiment setup, without any electrical noise interfering. This also vastly reduces the dead volumes of expensive solutions, as the tubing is much shorter.

Intuitive, convenient control 

The PPS is operated using a module within Scientifica’s ‘LinLab’ software, which is supplied free of charge. LinLab enables remote operation of the perfusion directly alongside micromanipulators, XY stages, microscope Z axis movement and temperature control devices. 

PPS-Control

 

Set perfusion protocols 

As an alternative to manually controlling the features of the PPS, custom protocols can be created, stored and recalled allowing the user to step away from any manual intervention of the PPS and return once the sequence has finished. This is invaluable when repeated tasks such as cleaning, priming or assay protocols are required, saving time and ensuring consistency. For added convenience, a data log is written for each experiment for evaluation and optimisation. 

Fast manual operation 

Using the graphical interface, the user can quickly and easily access the following functions: 

  • Activate and deactivate each of the inflow valves 
  • Divert the perfusion flow to the preparation chamber or waste, or recirculate the solution 
  • Commence and pause the pump 
  • Alter the pump speed, correlating to adjusted flow rates
