Aerosol-tight Applications
Fill Level
Thermo Scientific 75006476 LH-4000W 5-3
To achieve a uniform pressure onto the seal
,
turn the cap another 1
½
grip areas (some 15°).
Use the markings on the bucket for orientation.
Fill Level
The tubes are only to be filled to a level which ensures that the sample is unable to reach the top of the
tube during centrifugation. Therefore
,
fill the tube only 2/3 of the rated level.
Checking the Aerosol-Tightness
The aerosol tightness testing of the buckets depend
s
on the microbiological test process in
accordance with the EN 61010-2-020 Appendix AA.
Whether or not a bucket is aerosol-tight depends primarily on proper handling.
Check as needed to make sure your bucket is aerosol
-
tight.
The careful inspection of the seals and seal surfaces for signs of wear and damage such as cracks,
scratches and embrittlement is extremely important.
Aerosol-tight applications are not possible if the lids are open.
Aerosol-tightness requires the correct operation when filling the sample vessels and closing the bucket
cap.
