Geri®: An innovative incubator with integrated embryo monitoring system

The incubator for an embryo is absolutely critical and essential for its survival while being cultured outside of the uterus. Geri® is a compact modular benchtop incubator that incorporates time-lapse imaging to capture critical developmental stages of embryo development. Designed to offer an individualised and undisturbed incubation, Geri® provides stable culture conditions in an optimal environment.



Focusing on what matters; the embryo

  • Six individual incubators/chambers, designed to have a single patient in each chamber, with each independently controlled for the storage and preservation of embryos at or near body temperature1.
  • Each chamber has its own dedicated camera, capturing up to 11 focal planes and a best focal plane, embryo-cropped image every 5 minutes in 2560 x 1928 pixels. This unique feature eliminates the need to move embryos around the incubator, while at the same time minimising any movement of the camera1.
  • It is easy to see at a quick glance which chambers contain embryos, either by looking at the individual LCD screen for each chamber, or the homescreen of Geri® showing an overview across all incubator chambers.
  • Each chamber is able to be swapped in and out, independent of the other chambers, thus minimising down-time and the need to send Geri® away for repair.

Creating optimal culture conditions

  • Geri® has a gas purge function to flood the chamber and accelerate the process of restoring optimum gas levels, to re-establish the optimal environment in the chamber as quickly as possible with a recovery time of 3 minutes1.
  • Each chamber has its own CO2 sensor, monitoring the concentration of CO2 rather than flow of gas. This assures that your mixed gas has the correct CO2 level1.
  • Each chamber can be humidified with the addition of the Geri® Water Bottle, thus reducing evaporation of culture media and minimising changes in osmolality levels that may impact embryo development, even at day 5 or 6 of culture3.
  • We have incorporated redundancies into the chamber so even if one of two heating element pairs fails, the temperature is maintained by the other heating element pair. This maintains the temperature of the chamber and reduces the impact on temperature variations for the embryo1.
  • The Geri Dish® has 16 micro-wells for individual embryo tracking providing Geri® with a capacity to hold 96 embryos.



Real-time monitoring of embryo growth

Geri® enables you to monitor each chamber’s environment and control incubation conditions in real time to ensure the ideal condition for embryo growth is achieved. Here are a few key factors that can be monitored in real time:
  • Temperature: Geri® maintains a precise temperature in each chamber, within +/- 0.2 ºC of a user-specified set point1.
  • Gas flow: A regulator maintains a consistent gas flow1.
  • Independent in-built sensors: Temperature and gas sensors detect abnormal environment conditions1.
  • CO2: Temperature and CO2 conditions in each chamber can be monitored with an external probe2 for reassurance1.


Incorporating the latest time-lapse technology

The Geri® software is built on a modular approach. Embryos can be viewed on the Geri® instrument itself, or the images can be transferred to the Geri Connect® server to be stored and then played back through the Geri Connect & Geri Assess Software. You can even share these images with patients to make their journey a more personalised experience than ever before.




Testimonials from our embryologists at Genea

  • “Geri® is very user friendly, provide good quality videos and allow consistency within our lab.” Brooke, Senior Embryologist, Genea Kent St.
  • “The ability to have a live view of the embryos as they develop has allowed us to manage patient expectations better as well as pick up any abnormalities earlier.” Samantha, Senior Scientist, Genea Wollongong
  • “It makes it easier for the patient to understand what I’m saying. It also provides us with the ability to have in-depth communication with doctors, particularly when the patient has multiple embryos on day 5 and to explain how we’ve differentiated between them.” Diana, Fertilities Lab Manager, Genea Kent St.

Geri® in the lab

At Genea, the Geri® incubator has enabled our embryologists to watch and monitor the development of each embryo that is being cultured in each chamber, which provides embryologists and doctors with more information about embryo development.



  • Geri® is a bench top incubator that incorporates time-lapse imaging to capture critical developmental stages of embryo development.
  • Geri® has been recognised internationally and awarded Gold in the Medical Design Excellence Awards in New York in 2017.
  • Geri® has been awarded the Australian Good Design Award in the product design category in 2017.
