Microbiological Capabilities ❏ Customized 384 acrylic well plate
❏ Five layer sandwich plate lid
❏ Five flow adjustment valves
❏ Flow meter to control gas flow
❏ The TRL for the microbiology subsystem is a level 2 due to its concept only being formulated and no prototype being completed.

2. If powered, run from 120V AC electricity from a standard wall outlet with a 15-amp breaker.
1 Watt maximum from the flowmeter
UF Biofoundry Power can run from the 120V AC electricity from a standard outlet
10. Has a minimal operational lifetime of 10 years.
The flowmeter has a lifetime of 10 years
UF Biofoundry The flowmeter meets the requirement of being a minimum of 10 years.
11. Production devices cannot exceed $10,000.
$1,584.71 UF Biofoundry The cost of this subsystem takes up around 15% of the budget
18. Capable of incubation/hibernation periods from one hour to two weeks
12 Hours of battery lifetime UF Biofoundry Since the system can be kept on if the electricity goes out for 12 hours it should be enough time to get the electricity back on.
21. Can culture microbes in fully enclosed compartments or vessels that are easily interchangeable and that allow for media exchange.
SABr has one closed loop system that is enclosed with a sandwich lid and interchangeable with different containers.
UF Biofoundry This closed loop system can culture for fully enclosed vessels and allows for media exchange.
22. Accommodate existing culture plates of the following sizes: 6, 24, 48, 96, deep 96, 384.
With the customized well plate, it can hold the maximum size, 384.
UF Biofoundry Since the maximum size well plate is used for the customized well plates all of the other sizes can fit inside the system.
23. Accommodate existing conical tubes of the following sizes: 15mL & 50mL.
The translation system includes a section for conical tubes of both sizes.
UF Biofoundry The system does accommodate for the two different sizes of conical tubes.
Heating/Cooling Capabilities

UF Biofoundry Autonomous experience using simple customer interference
28. Can measure OD and FI in all individual wells of any accommodated well plate readings to provide culture condition data
2 separate sensors for separate readings
UF Biofoundry Successfully measures both OD and FI
29. Designed with respect to trade-offs in using monochromators vs. filter cubes for FI readings
mCherry filter cube set UF Biofoundry Allows lower cost and higher sensitivity
30. Achieve a light intensity of 1 kW/cm2 at 640 nm for several minutes. High frequency wavelengths would operate at a lower intensity as it becomes lethal to cells.
600 W/cm^2 at 643 nm UF Biofoundry Lowered intensity at higher frequency allows for a factor of safety when reading live cells

Overall Structure Capabilities
❏ The full-seamed weldment is made of 5052 aluminum with 2 access openings which are sealed to prevent contamination from external impurities
❏ The TRL is 2 for the overall structure because the concept has not yet been prototyped.❏ Changes are expected to occur once a physical product is made for testing
because the interaction between the customer and the product can’t be 100% predicted via models and formulas
