KONDUiT module

Walkaway TFF Automation

You can do it with Spectrum® KONDUiT

Monitor and evaluate conductivity, UV and temperature for automated process controls.

KONDUiT is an add-on module ready to use with Spectrum® KR2i and KMPi TFF Systems and Pro-Connex Flow Paths, with the ability to scale from 1mL to 1000L process volumes. Using single-use, gamma stable sensors, the KONDUiT can be used with hollow fiber or flat sheet TFF filters and can automate process control parameters defined by weight, conductivity, and UV independently or in conjunction with each other.

To the existing integrated functions of the KR2i and KMPi systems, KONDUiT adds:

  • End point conductivity control for ultrafiltration / diafiltration operations
  • End point UV control for diafiltering free drug from drug delivery particles
  • End point UV control for concentration of certain molecules
  • UV alarm for monitoring membrane breakthrough
  • Real-time temperature monitoring
  • Two independent temperature/conductivity readings
  • Simultaneous monitoring of 2 wavelengths: 260nm and 280nm
  • KONDUiT side view
  • 2 conductivity and 2 UV ports
  • KONDUiT side view
  • KONDUiT power button and communication port


Dimensions (L x W x H): 7 ¾ x 4 ¾x 4 ½
Weight: 1.6 kg
Pressure Range: Rated for pressure up to 75 psi (5 bar)
Conductivity: Range: 0.1 to 100 mS/cm

Accuracy: From 0.1 to 2 mS/cm ± 0.1 mS/cm; 2 to 50 mS/cm ±5% of reading; 50 to 100 mS/cm typically ±5% of reading
Temperature: Range: 0-70°C

Accuracy: Better than ±0.2°C (typically better than 0.1°C)
UV: Output signal: 4-20 mA sourcing with 400 ohm maximum at 24 VDC; scaled to 0-2 AU with repeatability of 1% of full scale (0.02 AU)

Typical Response Time: 1 second

Maximum Zero Shift: <2% of full scale (<0.040 AU)

Long Term Output Drift: <5% per month of full scale (<0.100 AU)
