The Sartocheck® 4 plus is the result of Sartorius 30 years experience in developing automatic filter integrity testers. Valuable productivity enhancing features and robust build quality have been combined with incredible ease of use to make the Sartocheck® 4 plus the only logical choice for integrity testing. The Sartocheck® 4 plus provides the following unique combination of benefits:

Integrity Test Methods

  • Bubble Point Test (BPT)
  • Diffusion Test (Diff)
  • Combined Test (Diff + BPT)
  • Pressure Drop Test
  • Water Intrusion Test (WIT)
  • Water Flow Test (WFT)
  • Multipoint Diffusion Test
  • Customer Specific Test
  • Automatic Test Time function for intelligent optimization of test times

Barcode Scanning

Using the optional barcode scanner allows easy and error-free entry of bag | filter cartridge data into the unit. Sartocheck® 4 plus automatically locates the suitable test program that matches the scanned bag | filter cartridge.

Cleaning Function

The patented cleaning function of Sartocheck® 4 plus (Bag tester and Filter tester) allows the user to perform reliable cleaning of the complete internal pneumatics even with aggressive cleaning agents (up to 1 M NaOH). This unique feature provides security of the integrity testing procedure while eliminating the need for costly down time and service calls. A fulfilled cleaning also generates a printout for full traceability.

Network Concept

The network solution for the Sartocheck® 4 plus incorporates the TCP-IP and FTP protocol standards, with data being transmitted via the Ethernet standard. Via standard RJ45 connection, all data can be easily up-loaded on a FTP server. Profibus communication can be used to allow bidirectional communication with process control system as a basis for complete automation.

Multiunit Concept

In order to increase productivity through parallel system testing, up to four additional MultiUnits can be easily connected to the Sartocheck® 4 plus. This provides the equivalent testing capacity of five Sartochecks operating concurrently at a significant cost savings to the end user.


Sartocheck® 4 plus ensures that all integrity tests are carried out with highest precision and accuracy. Our comprehensive Sartocheck® 4 plus validation documentation and world-class Service Team provide exemplary support for the user.
