We control our dilution cups very much to make sure they have as little deviation from 9 mL as possible. We regularly make statistics of our analyses, and this is the latest one we have done.
🔊EXPLANATION:
In the following graph you can see the amount of Dilucups classified according to 3 different volume intervals during the last 3 years:
- 9 mL - (1 to 0,4999 %) ➡ 8,91 mL to 8,955 mL
- 9 mL ± 0,5 % ➡ 8,955 mL to 9,045 mL
- 9 mL + (0,5001 to 1 %) ➡ 9,045 mL to 9,09 mL
❕Note: according to ISO standards the volume must be: 9 mL ± 2 % (8,82 mL to 9,18 mL)
Results are based on approximately 15.000 volume measurements per year.
📈 RESULTS:
In 2021, 99,97 % of Dilucups had a volume of 9 mL ± 1 %, of which 89,21 % were in the range of 9 mL ± 0,5 %.
In 2022, 99,9% had a volume of 9 mL ± 1 %, of which 84,45 % were in the range of 9 mL ± 0,5 %.
Last year, 99,92% had a volume of 9 mL ± 1 %, of which 91,72 %* were in the range of 9 mL ± 0,5 %.
*This increase compared to 2022 is not a coincidence. Since summer 2023 we have been working harder so that the volume is in the range of 9 mL ± 0,5 %. This is because we know how important it is to have a highly accurate volume for many industries, such as probiotics.
📝 CONCLUSION:
Almost all Dilucups have a volume of 9 mL ± 1 %, with normal values being in the range of ± 0,5 %.
The results are consistent over the years, and our goal is to continue increasing the percentage of Dilucups that have a volume of 9 mL ± 0,5%.
