Improve workflow efficiency by choosing the autosampler option that best fits your throughput and experiment requirements. Three models of autosamplers are available to deliver walk-away automation seamlessly integrated with your Attune NxT Flow Cytometer for increased productivity.

“The Attune NxT autosampler allowed us to process multiple 96-well plates in a day, enabling high throughput experiments that could not be performed on other flow cytometers.”

“The Attune NxT is a very well-built instrument, we are very happy with the Attune NxT. The automated Autosampler is a real plus when it is combined with the acoustic focusing because it allows you to count very diluted samples fast. It’s very precise and gives reliable event counting.”

Our autosamplers are compatible with many different plate formats, including 96-well, 384-well, and up to 2 mL deep-well plates. The autosamplers give you a range of flexibility. An intelligent probe design minimizes clogging and carryover (0.5%) and helps prevent damage to the instrument. Conversion between plates and tubes is easy with a one-click transition. And autocleaning is performed automatically upon instrument shutdown. 


Unlike other systems that use shaking for mixing, our autosamplers aspirate samples for mixing. Aspiration for mixing is a novel approach that both ensures homogeneity of the sample and is gentle on cells to help ensure cell viability. 

Consistent results across all wells and across plates

The Attune NxT Flow Cytometer Automation configuration with the Attune Autosampler demonstrates consistent results regardless of whether the sample is delivered from a tube or from a plate


Attune NxT Autosampler offers consistent results regardless of sampling method. 


Lysed whole blood was stained for CD45, CD4, and CD8 markers, aliquotted into both a tube and a plate, and analyzed on an Attune NxT flow cytometer. Minimal variation was observed between the sampling modes.

To determine consistency across wells and plates,  lysed human whole blood was labeled with fluorophore-conjugated monoclonal antibodies for CD45, CD3, CD4, and CD8 targets. The labeled cells were fixed, then added in equal amounts to each well of two 96-well plates, and acquired on a 4-laser Attune NxT Flow Cytometer with Autosampler. The concentration statistic representative of events/μL of any given population and percent positive are examined in depth.

Robotic automation

Extend your unmanned runtime settings and scalability with robotic integration applications for the Attune NxT Flow Cytometer. Our range of automation solutions include robotic plate taxiing, extended fluidics, temperature-stable plate storage and software for operations, scheduling as well as integration can be leveraged to help you get the most from your solution.

Automation setup

The robotic arm offers active and passive protective safety features, demonstrated reliability, and flexible configuration options for arrangement and storage. Operation is managed by Thermo Scientific Momentum Scheduling Software, established with instrument drivers available for over 200 instruments. The dashboard facilitates dynamic scheduling for active prioritization, visualized progress, and plate tracing. Extended-run fluidics allow for up to 19.5 hours of unattended continuous runtime under specific run conditions.

The Orbitor RS2 Microplate Mover can handle 20 standard microplates or 9 deep-well blocks and a self-scanning internal inventory to ensure flexibility. The system can de-lid and re-lid plates as they are loaded, unloaded and stored to mitigate evaporation.

Thermo Scientific Orbitor RS2 Microplate Mover

The Orbitor RS2 is a compact platemover with unmatched speed and accuracy for robotically automated flow cytometry. The system’s innovative bi-directional telescoping arm provides exceptional reach and precision making it one of the most flexible movers in the market. The integrated barcode scanner enables sample tracking, barcode transmission and inventory management, while the plate detection in the gripper helps to eliminate labware handling errors and reduces the risk of lost samples.

Cytomat automated incubator

The Cytomat automated incubator uses orbital shaking that uses a synchronized dual magnetic drive system that ensures consistent shaking amplitude across all microplates without influences from load, position or number of plates.  


The synchronized dual magnetic drive system (located at the bottom and top) ensures consistent shaking amplitude across all microplates without having any influence of load, position or number of plates. An inductive wear-free driving mechanism allows for no particle emission or belts to change. 


The system supports a wide range of applications with individual speed settings of each Tower Shaker from 100-1200 rpm with oscillating amplitude of 2 mm (3mm option available).

The Cytomat incubator is easy to set up and flexible.  An active microplate clamp mechanism secures plate and lid separately to prevent abrasions on microplates during shaking. For optimal assay flexibility you can mix both Standard and Tower Shaker. 

Attune NxT external fluid supply

Attune NxT External Fluid Supply (EFS)

This 10L External Fluid Supply extends the period of continual operation. The EFS fits under the bench or on an adjacent cart connected to the Attune NxT flow cytometer by umbilical cords. Active monitoring of the EFS ensure operator is notified of issues encountered. 

Integrated Software

Dynamic scheduling in the software allows users to successfully create multiple workflows.


The software’s compatibility drivers support over 200 instruments. They have proven success in numerous implementations and can speed your integration project.

Momentum Integration Software 

The Momentum Integration Software includes easy to learn and use dashboard for operations, scheduling features to handle multiple workflows and compatibility drivers to speed implementation. 


A key factor to choosing your automation solution is ensuring that the software is both performant and easy to use. The dashboard in the  Momentum Integration Software is fast to learn, and helps users to actively prioritize and reprioritize runs, visualize progress and trace plates.
