Ef 100 mm f 2.8l usm lens

Manufactured by Canon

The Canon EF 100 mm f/2.8L USM lens is a prime telephoto lens designed for use with Canon EOS cameras. It features a maximum aperture of f/2.8, a focal length of 100 mm, and a ring-type Ultrasonic Motor (USM) for fast and quiet autofocus operation.

Evaporation Measurement in 3D Printed Microfluidics

3D printed microfluidic devices (N = 7) with theoretical capacity (~101 ml) facilitated the measurement of the rate of evaporation. Sealing of the inlet and outlet of a device with parafilm after filling with DI water (dyed blue for visualization) formed the complete device for testing. Measurement of the initial sealed device mass (inclusive of water, film, and printed microfluidic system) using a microbalance (Sartorius Quintix 224-1S, Germany) enabled recording of mass loss at 2 and 24 hours. Devices were maintained at room temperature in a controlled laboratory environment reflective of anticipated use environment (22°C, 55% RH). An optical camera (Canon 90D, Canon EF 100 mm f/2.8L USM lens) facilitated observation of visual changes to fluid levels at each measurement interval.

Phantom Arm Flow Visualization

Check if the same lab product or an alternative is used in the 5 most similar protocols

Phantom arm assemblies for studies of flow used tubing [Tygon, ID = 1.5 mm, outer diameter (OD) = 3 mm] embedded in a 3D-printed model of an arm (Black Resin, Formlabs Form 2). A calibrated pressure displacement pump (Fluigent, France) controlled the pressure of water introduced into the system. Each measurement consisted of a “fill test” in which water at a fixed pressure (2 kPa) entered the device until full. Simultaneously, the progression of the fluid front was recorded using a camera (Canon 90D, Canon EF 100mm f/2.8 L USM lens) at 30 frames per second. Three separate phantoms reflective of different arms (infant, r = 15 mm; adult, r = 30 mm; flat/control) were used for the testing described above.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
