The lab is using a specific tube which requires a specific speed at a specific time. Have you checked speed calibration at the speed they are using, with the rotor they are using?Ī: This is a speed or time problem. I would recommend that you try increasing the time, as a quick possible solution. Or maybe, if it is taking longer to get up to speed, they will need to increase the program time. What could be the cause of this? Are there any things that I might do to fix this or is it them doing something wrong?Ī: Perhaps it is braking too fast, causing the separated fluids to re-mix. She is saying that rotor turns, but we can’t separate the samples (blood). Then, I got a call from the lab assistant. I have given it a go at different RPM levels, it is turning, everything looked fine. I changed a slow charging resistor, 15VDC Voltage source and some connectors. Q: I have recently repaired one of our centrifuges.

field which greatly reduces heat and insulation problems it is mounted on an antivibration support stabilized by a suitable mass which makes it stand imbalanced loads, within certain limits, without suffering or causing damages. The stainless steel centrifugation chamber is extractable both for easy cleaning and or inspecting the motor carbon brushes and the service fuse. The Jouan B4.12 centrifuge has a sheet iron case, varnished with epoxy powder.
