Why to adopt sterile “Daily Shift” aspirating head?
The “Daily Shift” can be used during the complete working shift, all day round.
They have a certification of sterility.
They are used in case of autoclave problems or shift over activity.
What’s the difference between “Official Calibration” and “in House monitoring”?
“In House Monitoring” is a test performed by the company staff to control the unit works properly and it is not damaged (e.g.: dropped, mishandles, battery worn out, etc.).
“Official Calibration” is a test performed by a third party to obtain an official document requested by official institutions like the FDA.
Why and when a statistical table is used for the correction of counted CFU on the culture plate?
If the CFU on a culture plate is very high, there are high probabilities that more microorganisms impacted on the same points of the agar.
For this reason a statistical table (Feller) is used for the correction.
