Design

Lachesis is a compact control unit supporting the Clio and Thalia type of diaphragm Single-Use-Pump cell's. Lachesis differs from Clotho in that the proportional valves and internal manifold is larger facilitating higher drive gas volumes to be regulated.

Driving Clio and Thalia SUP's requires pressure above and lots of vacuum capacity below atmospheric pressure. The SUP cell drive gas pressure is continuously adjusted by sets of proportional valves inside Lachesis. Intelligent microprocessor with advanced PID algorithms get information from Laser and pressure sensor's.

Specification

Lachesis needs to be connected to a pressure and vacuum source with sufficient capacity - then the spec is:

  • Drive of one big Clio or Thalia SUP cell's
  • Pumped volume (Cardiac Output) according to stroke length and cell size
  • Stroke length, %: 1-100
  • Atropos can inform about a velocity according to a diameter, m/s: 0.1-15

SUP size, name

Clio/Thalia M140

Clio/Thalia M200

Clio / Thalia M300

Stroke Volume, SV, mL/stroke

900

2,500

 

Cardiac Output, CO range, mL/min

10-10,000

20-25,000

 

Lachesis can of course be driven by in lab installed pneumatic air and vacuum.

Don’t forget that the vacuum pump of good capacity should not be mounted more than 5 meter from Lachesis with ID 25 mm. Or the tubing systems longer then 5 meter should be at least ID 50 mm size.

Communication

  • Internal 5” touch sensitive TFT display or external to PADs or smartPhones via Wi-Fi for programming and info from the built-in webserver
  • USB port for USB adapter/Wi-Fi connection and 5 VDC / 1 amp charging smartPhones
  • RJ45 for IP/TCP via LAN and ModBus or OPC-UA communication
