The most fun serial dilution method!
| April 16, 2024
Dilugent Shaker indicates you which Dilucup to use with different colours, making serial dilutions a guided experience, as well as entertaining 😉
Tip: Dim the light in the roomand you'll see what colours come out of Dilugent Shaker… They are amazing!
Happy Easter!
| March 27, 2024
Did you know that the daffodil (or Påskliljan in Swedish) is the flower most associated with Easter in Sweden?
After a long winter, the streets have already been filled with little flowers of different colours all over the grass and they bring a lot of joy (apart from allergies ;)).
We wish you a Happy Easter and hopefully some sunny days to enjoy your days off! 🙂
Highly accurate diluent volume
| February 26, 2024
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%.
New reactor installed
| January 19, 2024
This week we completed the installation of our new reactor and its heat exchanger!
With it we can produce up to 50% more Dilucups daily!
A necessary investment to meet the growing demand for these fantastic dilution cups.
New year new solutions in the lab!
| January 02, 2024
A simple, comfortable and fast method that allows you to save a lot of time with the serial dilutions!
This system has many benefits over traditional methods and is essential in laboratories where multiple dilutions are made.
Merry Christmas and
Happy New Year 2024!
| December 19, 2023
We all at LabRobot wish you a Merry Christmas and a Happy New Year 2024 or as we say here in Sweden “God Jul och Gott Nytt År!”
Have a wonderful and happy holiday time with your loved ones!
You can safely use micropipettes with Dilucup®
| November 16, 2023
Serial dilution with tubes and a micropipette can be challenging because the risk of contaminating the inside of the tube with the pipette is high. That is why straws are often used, but how can you be sure about the accuracy of the pipetted volume?
The good thing about Dilucup is that since it is a low cup, you can safely use a micropipette and get the best possible volume accuracy.
Higly accurate volume
| October 23, 2023
The most important thing when performing serial dilutions is that the volume is accurate. Otherwise, you can forget about having a good result because the accumulated error will give you a wrong enumeration of microorganisms.
Volume statistics (based on 25.000 measurements):
- 94,4 % -> 9 mL ± 0.5 %
- 99,95 % -> 9 mL ± 1 %
- 100 % -> 9 mL ± 2 % (according to ISO standards)
Methods where filling tubes or other recipients is done in the laboratory cannot guarantee a volume as accurate as Dilucup.
Distributor meeting
| September 27, 2023
Last week we had the pleasure of meeting with most of our distributors and it was a great success!
Thank you all very much for the positive energy and for making those days an inspiration for everyone.
We look forward to seeing you next time!
Keep it simple!
| July 24, 2023
Work in the lab can be chaotic and stressful...
so why make it more difficult?
Keep it simple with the Dilucup System!
New award from AddLife

We are so happy to share that we received a new award for our sustained growth in the Addlife group!
This award is the result of the hard work, dedication and innovative strategies of our entire team. We could not achieve this without the support and trust of our valued customers, who are the key to our success.
Thank you for your continued partnership!
Latest volume accuracy analysis
| March 15, 2023
The volume of a diluent must be accurate to have reliable results and according to EN ISO 6887-1: 2017 the volume should not deviate from 9,0 mL ± 2 % (9 mL ± 0,18 mL).
We want to be better than this and that is why Dilucup® aims for a volume range of 9 mL ± 1 %.
99,95% of the 25.000 latest Dilucups analysed in our QC laboratory had a volume of 9 mL ± 1 %, with an average of 9 mL + 0,26 % mL (9,02 mL) and a SD of 0,21 %.
Pretty good volume accuracy, don’t you think?

The ergonomic solution for serial dilutions
| February 7, 2023
Have you ever got pain in your wrist or joints?
If so, you surely know how limiting it can be, requiring sometimes even months of sick leave to recover.
When you use a vortex mixer vibrations are absorbed by your hand/wrist. With the Dilucup system, the shaker is the one that absorbs all movements, so your joints don’t suffer any damage.
Our serial dilution system protects you against repetitive strain injuries in hands or wrists.
It’s really comfortable to use. Try it and you won’t regret! Don't let a vortex ruin your well-being!
How to make multiple serial dilutions at the same time
| January 10, 2023
Making many serial dilutions can be time consuming and monotonous.
Have you never thought about making multiple serial dilutions at the same time?
This is possible with Dilugent® Shaker Pro!
You can dilute up to 7 samples at the same time without getting lost.
Watch the video to see an example!
How to enumerate microorganisms?
| July 28, 2022
How to enumerate the microorganisms in a food sample using Dilucup?
- First homogenize the sample if it is solid. This is the first 1/10 dilution.
- Once the sample is suspended or if the sample is liquid, serial dilute it using Dilucup.
- Plate 1 mL of the selected suspension(s) and incubate.
- Count the colonies (the plates should have between 30 and 300 CFUs to get a statistically valid result).
- Divide the average number of CFUs per the dilution level to get the number of microorganisms per mL or g in the original sample.
