Most pipette manufacturers provide specifications for both the accuracy and precision of their pipettes. Because the Checkit directly measures delivered volume rather than relying on gravimetric analysis, there is also no need to use correction calculations that account for these factors. This can help identify variation in delivered volume due to pressure, humidity, or temperature differences between the calibration environment and the experimental environment. The markings on the Checkit reflect this variation.Ī note on environment: One advantage of the Checkit is that it can be used in the same room in which the experiment will be conducted. When a pipette is used near the bottom of its range, the measured volumes will vary more, and are also more strongly affected by slight variations in pipetting style or environmental factors like humidity. Piston pipettes are most accurate at or near their nominal volume (the maximum volume the pipette can deliver). If your institution requires pipette calibration on a specific schedule, you should adhere to this schedule and use the Checkit as an extra verification step between scheduled calibrations.Įxpected performance at different volumes The Pipette Checkit® is a tool to identify potential volume delivery errors for pipettes. This tool allows users to check the accuracy of their pipettes in seconds right in the lab. I feel like I may have missed some undocumented step though, and was hoping you all might be able to help.Pipette Checkit Pro model for 200uL pipettes by Next Advance. I'm on Arch Linux with the linux-surface kernel installed, have MESA up to date, and went through all of the install instructions on the github. I'm a bit more familiar with the AMD GPU side of things on my gaming desktop, but I'm having trouble getting started on the Intel side of things. I was wondering if anyone here is familiar with controlling the intel GPU onboard the Surface Pro, how to check its current clock speed easily, and how to bump it up to one of its higher clocks if possible. I am suspicous, however, that I should be getting slightly better performance than I currently am, and feel like maybe the iGPU isn't ramping up under load, particularly because my battery life doesn't change when I'm playing a game or just editing text in KATE by much.
I do hobbyist PC building and gaming among other hobbies and whatnot. Before we begin, I just want to say that I am aware that the Intel integrated graphics are not the most powerful things in the world.
