MoFlo Astrio sorter (Beckman-Coulter)

This flow cytometer provides the technology and the power necessary for the simultaneous reading of more than 20 fluorescence parameters and for the sorting of events, even if they are rare, in a population of heterogeneous objects. It is equipped with 22 photomultipliers, and 5 laser lines (355 nm / 100 mW; 405 nm / 55 mW; 488 nm / 150 mW; 561 nm / 200 mW; 640 nm / 100mW). Sorting can be accomplished in six ways (harvest in 5ml or eppendorf tubes) or on a plate (6 to more than 96 wells) with a reading speed of 70,000 events per second. Since January 2015, the analyzer-sorter has benefited from a module allowing the detection of small events (≥200 nm).

Although it is difficult to train for sorting with occasional use, training in autonomy in analysis is possible and recommended for routine experiments.

To define the type of device most appropriate to your problem and the desired level of access, a first discussion with one of the members of the platform is recommended.

Three levels of access are offered to our users:

The provision of assisted service concerns work carried out by the platform on behalf of a user. It implements techniques and know-how mastered by the platform. The work done in this type of service is not inventive.

An analysis of the results obtained will be provided in PDF format. It implies recognition of the engineer’s investment in possible publications. The platform does not guarantee the retention of data at the end of the service.

The use of equipment requires prior user training by one of the platform members. This training results in the acquisition of autonomy allowing the user to reserve the equipment on which he has been trained.

Use of the equipment after training is suggested when the user’s needs require repeated use of the equipment.

Before being fully autonomous on the machines, the user must agree to comply with the platform access conditions by completing an “access request”. The user’s team leader must also agree by signing this document.

The platform must be thanked in any publications.

In addition to the training provided as part of our service offers to lead to the autonomy of use of equipment, Imagerie-Gif organizes training in the form of theoretical courses, practical work and tutorials in specific areas of cytometry : link to training page.

The purpose of scientific collaboration is to remove a methodological barrier, in direct collaboration with a user. Collaboration is particularly implemented when a user’s request requires adapting protocols or carrying out specific developments.

The engineer involved will be considered in the position of co-authors in a possible publication.


The funding requests necessary for the development of the Imaging-Gif division make it essential that the activity of the platforms be explicitly recognized.

Conditions of Use

  • Access to equipment

Before any training or service, the user must complete an “access request” to agree to the proposed service and the proposed access terms. The user’s team leader must also sign this document. Upon signing, the team leader thus acknowledges having read and accepted the terms of use of the platform’s resources.


By signing this document, the user AND his/her team manager therefore agree to:

– respect the health and safety rules and the operating rules of the platform,

– provide all the information on the samples analyzed, in particular with regard to the potential risks for the manipulator and / or the material and inform the platform engineer of any change in biological material,

– respect the reserved hours of use,

– accept the billing conditions for services performed on the platform

– notify with acknowledgments any publication / presentation of data acquired on the platform

– enhance the investment of engineers


By signing this document, the platform for its part undertakes to:

– advise and guide the user towards the system (s) most suited to their needs,

– provide the user with maintained, checked and calibrated equipment,

– train users to support them towards partial or total autonomy in using the desired equipment,

– provide technical and / or scientific support,

– improve the quality of services offered by implementing a quality management system certified ISO9001 and NFX-50-900.


If these instructions are not followed, access to the various services may be called into question.


  • Sample compliance

The platform laboratory is only authorized to handle level-1 risk biological samples. Higher-level samples must be inactivated before being brought to the platform. The platform is not equipped to support the study of radioactive samples.

In certain cases, the platform engineer reserves the right to refuse a service if he judges that the samples present too many biological risks.


  • Machine reservation

Reservation is compulsory and is done via the GIPSI website.

Once trained in the use of one or more equipment, the user receives his identifiers by email in order to be able to connect to the intranet of the GIPSI website.

To access the reservation, simply log on to the left of the screen with the email address and password received. Those who have lost their password can request a new one by clicking on “Forgotten?…” Below the connection login.

To reserve equipment, simply select the platform of your choice in the “Platforms” tab, then go to the “Reservations” tab.


  • Storage of data and analysis results

The platform does not guarantee the retention of data at the end of each session. The user is therefore solely responsible for archiving and safeguarding his personal data.


The data acquired or processed can be retrieved by the user at the end of each service (autonomous or assisted by the engineer) on a USB key or on an external hard drive. In the case of a service performed by the platform engineer, a hard copy or computer copy (sent by email) can also be provided to the user at his request.


NOTE: The duration of the acquisition / analysis session MUST take into account the transfer time of acquired or processed data. No data should remain stored on the local drive.


  • Equipment maintenance

The platform monitors the stability and good condition of this equipment. This is essential to ensure our users have good reproducibility in their acquisitions.

For his part, the user is obliged to report any problem encountered when using the devices by completing an anomaly section made available on his reserved slot on GIPSI.


  • Intellectual property & confidentiality rules

Intellectual property

The know-how and knowledge used by Imagerie-Gif to provide the services remains the property of the CNRS; consequently any improvement in know-how will remain the property of the CNRS. The property of the results of the services belongs to the customer.



Confidentiality rules

Each party (user and platform) undertakes not to publish or disclose in any way whatsoever the scientific, technical or commercial information of the other Party, and in particular prior knowledge belonging to the other party of which it may have knowledge during the performance of the services and this, as long as this information is not accessible to the public. This commitment will remain in effect for five years (5 years) from the date of issue of the invoice.

Any publication or communication from the user relating to the results of the services must indicate that these results were obtained by the platform. It must in no case disclose the know-how implemented by the platform.

  • GMOs include microorganisms (bacteria, viruses, yeasts, etc.), plants and transgenic cell cultures
  • Before disposal, all GMOs must be sterilized by treatment with bleach or autoclaving
  • Transgenic plants must be cultivated and handled in a greenhouse or in enclosures according to the rules which can be consulted in these places and on the Intranet.
  • The level of containment (L1, S1, S2 and S3) required for each type of experiment has been notified for each project by the Commission for Genetic Engineering (CGG). This information is available for consultation in the application files for the contained use of genetically modified organisms (groups I and II) submitted to the I2BC secretariat and available on the Intranet
  • Any new type of experiment must be the subject of a request for modification of the GMO contained use approval file.


  • Radioactivity: Specific measures

The user using radioactive markings must notify the technical manager of the platform from the first appointment.


  1. Training

Engineers inform and advise users for their training needs and requests. They will eventually set up specific training appropriate to the needs expressed.


  1. Use of IT resources

Each user of the Platforms hosted at the I2BC and using the I2BC’s IT resources must be aware of the I2BC IT charter.

It is strictly forbidden to use the computers dedicated to the management of the Platform equipment for purposes other than the acquisition or analysis of data related to the equipment (prohibition of Internet or intranet consultation, email, installation of programs, etc.).


  1. Use of collective technical resources

Engineers are responsible for maintaining equipment and laboratories. However, it is essential that the conditions and rules of use are strictly applied by each user. Platform engineers must ensure that users are trained and informed about security rules. They reserve the right to prohibit access to the Platform in the event of non-compliance with rules of behaviour.
