MasSpec Pen Device and Priming

Check if the same lab product or an alternative is used in the 5 most similar protocols
Chemicals and Reagents. Sterile water (Deerfield, Illinois, USA) commonly used during surgery was provided by the clinical staff and used for all analyses. Human whole blood was purchased from BioIVT (Westbury, NY, USA).
Silicon tubing, PTFE tubing, and heat shrink tubing were purchased from Kinesis (Vernon Hills, IL, USA), MilliporeSigma (Burlington, MA, USA), and Newark element14 (Chicago, IL, USA). Luer-locks were purchased from Cole-Parmer (Vernon Hills, Illinois, USA). The other materials used to 3D-print the MasSpec Pen devices were described in detail in our previous report.( 28)
MasSpec Pen Device and Operation. The MasSpec Pen devices were produced in the laboratory as previously described (28) . All devices were discarded after each surgery observing universal precaution measures. of the MasSpec Pen devices. The control box was equipped with a switch to alternate the "priming" and "analysis" functions between the two syringe pumps. Under "priming" function mode, the syringe pump was activated by pressing the "Refill" button, allowing pumping of 2.5 mL of water to fill the 4.5 meter PTFE tube (~ 15 seconds).

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.
