How to enumerate microorganisms?

By Elisabet | July 28, 2022

How to enumerate the microorganisms in a food sample using Dilucup?

  1. First homogenize the sample if it is solid. This is the first 1/10 dilution.
  2. Once the sample is suspended or if the sample is liquid, serial dilute it using Dilucup.
  3. Plate 1 mL of the selected suspension(s) and incubate.
  4. Count the colonies (the plates should have between 30 and 300 CFUs to get a statistically valid result).
  5. Divide the average number of CFUs per the dilution level to get the number of microorganisms per mL or g in the original sample.

Twice as many samples

By Elisabet | August 31, 2021

Twice as many samples in the same space with DilucupŸ Elegance. The design of DilucupŸ allows the blisters to be packed in a way that significantly reduces footprint. Less volume equates to less storage and transport space, resulting in less impact on the environment. Blisters from opened bags should be stored in the fridge and consumed within 3 months. If the bags are not open, they can be stored for up to 30 months at room temperature.

High speed vortexed

By Elisabet | July 21, 2021

The design of DilucupÂź allows its rotation at high speed (400-660 rpm) on Dilushaker III or DilugentÂź Shaker without spilling.

Once a lab has moved to DilucupÂź it doesn't move back to tubes!

DonÂŽt you believe it?

Accurate volume guaranteed

By Elisabet | May 27, 2021

  • 90,9% had a deviation of 9,0 mL ± 0,5%
  • 0,3% between -0,5 and -1,0%
  • 8,8% between +0,5 and +1,0%

"HĂ„ll Sverige Rent" movement

By Elisabet | May 5, 2021

LabRobot was happy to participate in the Swedish movement “HĂ„ll Sverige Rent" (= Keep Sweden Tidy) and we dedicated a few minutes of our lunch break to collect plastic waste around our building.

If we all would do the same frequently, we would greatly reduce the amount of plastic materials in the nature and the oceans!
