Dear all, we are in the process of issuing a Performance Qualification Protocol on a glass vials washing machine.
The tests decided to be included are the following:
- Particles counting on 5 glass vials before entering the washing machine (i.e. the washing cycle)
- Particles counting on 10 vials (beginning), 10 vials (middle) and 10 vials (end of the washing cycle)
- Inocculation of 10 test vials with KCL as for a challenge test so that to pove abcense of Cl- at the end of the washing process.
We were considering to add also a fluorescence test by microspheres into 10 test vials for this reason.
However, do you know where we can purchase a relevant package. I think they are sold in the market in powder form (micro spheres). Do you know the concentration per vial? Do you know what ammount (i suppose in solution - ml) each vial shoud be added with? Should this ammount vary depending on each vial’s capacity?
We shall be using vials of 50, 100 and 250 ml capacity.
Thank you all.
