We are in the process of switching our specimen collection tubes to Greiner Vacutte (previously we used BD). For some reason, with one of our STAT fuges, the stoppers keep coming off while being spun. Not all the time but enough to be annoying.
The centrifuge in question is a Hitteck EBA200. The vendor has recommended a certain insert for these Greiner tubes, but they still keep popping off at random. The stoppers are slightly different from the BD tubes, but we cannot see what is causing this.
If anyone has any ideas for fixing this they would be appreciated. We are trying to see if Greiner has any ideas.
I have 2 Helmer refrigerators, a freezer and a platelet incubator all using paper charts/ changing every 7 days.
My paper charts in the refrigerator finish a full hour or more ahead of the other 2 even after getting changed at almost the exact same time the platelet chart rotator being the most accurate.
Batteries look fine on the screens.
