Benchtop Cell sorter

 
CYBR Perspective Standard-W.png
 
 

Our team was commissioned by a medical device start-up who wanted to upset the laboratory device market with a compact version of a cell-sorting device that used to take up whole sections of laboratories by replacing them with this benchtop-sized model instead. They wanted to eschew the medical device aesthetic in favor of simplicity and accessibility.

DESIGN CONSIDERATIONS:

• Sterilizable, corrosion-resistant materials required

• Internal sheet-metal chassis design required

• 12-inch touchscreen required

• Operates in biohazard cabinet:
maximum working dimensions of 50”W x 30”H x 24”D

• 3 internal compartments: Sorting, fluidics, and computation

• 3 access areas:

Hourly – Sample loading

Daily – Operational fluid loading

Weekly – Pump maintenance

Client-provided files

This assemblage was provided by the client for inclusion in the primary assembly.

Sheet metal chassis

A structure was developed cooperatively with the client’s internal engineering team and our design and engineering team.

 
 
 

Process

During our concept refinement phase, two conceptual directions were blended to achieve a functional form that was well-received by the client.

Revision A

Meeting all the enclosure challenges at that time, the first revision of the machine met client ideals but drew out complications that weren’t understood initially.

Revision B

Over a few subsequent months, the internals were rearranged and the enclosure grew in width to include superseded components.

With and expected use of 1 to 2 times per hour, door access was afforded in the front, while keeping within the maximum operating dimensions, through a modified 4-bar hinge system.

With a less frequent access necessary, the side and top doors were made for low-level maintenance and repair.

Four trim levels were planned based on specific configurations for different laboratory use-cases.

 
 
 

Working Prototype

Finally, a full scale working prototype was made from folded sheet steel, machined aluminum, custom glass, 3-D printed panels, and off-the-shelf electronics.
