Boost efficiency and secure long-term success

Complying with quality requirements and regulations in an IVF lab is crucial, but takes time and effort.

Log&Guard eliminates time-consuming manual procedures and eliminates the weak spots in manual monitoring. Measurements are standardised for greater reliability and human error is no longer a risk factor.

Made for the unique challenges of IVF

Log&Guard is specifically designed to automate and standardise frequent work in the laboratory, increasing quality and freeing up time.

Log&Guard gives you automated 24/7 monitoring of all critical parameters in embryo culture and cryostorage. The system consists of a network of independent precision sensors for temperature, CO2, O2, pH, ambient temperature, humidity and VOC, connected to a central unit that displays the readings and saves them permanently.


Powerfull controller for monitoring and warning

Packed with advanced technology yet highly compact, the controller is the brain of the Log&Guard system. A built-in backup battery ensures continuous operation even during a power failure. The onboard modem
sends notifications and alerts to your designated mobile phones.

Easy to use software program

Log&Guard operates on a web interface based software platform, easily accessible from any computer in your local network, and does not require a separate computer.

Alarm conditions and thresholds, measurement intervals and many other parameters can be set individually to perfectly adapt the monitoring network to your individual lab. Measured data can be downloaded for long term storage.

Never miss an alarm

The Log&Guard system will alert you in case any parameter is out of range. Besides acoustical and optical alerts in the lab you can also be notified by text messages on your phone.
