Automatic integrity test device for testing the integrity of membrane filter cartridges

Home - Products - Integrity testers - TECHNOCHECK-3

TechnoCheckTM-3 is an automatic device for testing the integrity of membrane filter cartridges used in biopharmaceutical industry.

To ensure the quality of manufactured products in accordance with GMP requirements when using filtration systems, it is necessary to check the integrity of the membrane filter cartridges.

Technofilter has developed TechnoCheck, the first Russian automatic integrity test device. It is easy to operate and allows performing integrity tests according to basic standard methods.


The device is designed for testing systems:

  • with flat disk membranes;
  • with filter cartridges;
  • with filter capsules.

Measured parameters

  • Bubble Point
  • Forward Flow or Diffusion 
  • Pressure Drop
  • Water Flow

Features and benefits

  • Accuracy, fast and reliable measurement.
  • Operational control and indication of results on touch control panel.
  • Fast program selection and data input.
  • Easy data reading due to clear display (7").
  • User – friendly menu design and online hints facilitate the user operation.
  • The integrated printer for printing test results ensures data storage.
  • Reporting of measurement results in automatic mode using compact printer.
  • The change function enables changing programmed test parameters.
  • Freely programmable test allows testing filters produced by different manufacturers according to individual integrity test parameters.
  • High reliability of the device ensures long service life.
  • Storing the test results in external USB-flash memory. 
  • Optionally the device can be equipped by QR code reader for express filter’s data input. 

Advantages of TechnoCheck®-3

1. Calibration procedure is significantly simplified.

TechnoCheck®-3 is self-calibration device attached with detailed instructions for the calibration procedure. There is no more need to send TechnoCheck®to the manufacturer for calibration.

NPP Technofilter can also send a specialist to calibrate the device at the customer's enterprise.

2. EasyAccess 2.0 technology allows you to get remote access and to manage the device using a computer or tablet.
