Sample preparation with the Dilucup System

LabRobot Products AB has invented, developed and patented a new concept that makes serial dilutions easier, safer, quicker and cost-effective. Using the Dilucup System you simply:

  • Add the requested number of prefilled Dilucup  in the Dilushaker.
  • Tear off the protective film
  • Add 1 ml sample to the first Dilucup
  • Start the shaker by moving your hand in front of the optic sensor .
  • When the Dilushaker stops, the 1:10 dilution is ready.
  • With a new pipette tip, collect 1 ml from the first cup and release it into the second cup in order to perform the next dilution (1:100).
  • Start the shaker by moving your hand in front of the optic sensor.
  • Repeat this operation until the final dilution rate is reached.

 

Some years ago, the common way to dilute microbiological samples 1:10, 1:100, 1:1000, etc. was to prepare own test tubes. These tubes were filled with a diluent (for example Pepton-Salt), sterilized in an autoclave and then stored in a fridge. After use, the tubes needed to be emptied and washed in order to be ready to be filled again. This process was both time consuming and expensive. It could also happen that evaporation during autoclaving was uncontrolled, thus generating volume deviations able to affect the accuracy of the analysis.

The Dilucup System allows a real standardisation of the dilution process and reduces the variability between technicians, usually observed in traditional microbiology.

Cost saving
Cost saving

The reasonable cost of the ready-to-use Dilucups combined with the significant increase of the laboratory efficiency is contributing positively to the lab economy.

Time saving
Time saving

It’s much quicker to perform dilutions with Dilucup than with standard dilution tubes. Time saving can be up to 10 seconds/dilution step.

Prevent work injuries
Prevent work injuries

The repeated use of a vortex mixer can generate Repetitive Strain Injuries. With Dilucup, all the vibrations are absorbed by the Dilushaker. The use of plastic materials is also a safety factor, should something go wrong.

Increased quality
Increased quality

This is obtained through the standardization of the dilution process (less variability) and the accurate volume of the diluent in the Dilucups. All Dilucup batches are quality controlled and delivered with a QC Certificate.

Easy storage
Easy storage

The sealed Dilucup boxes can be stored at room temperature up to 20 months. For specific infomation, please read more about Dilucups.

 

Dilushaker

The shaking is started immediately through the activation of an optic sensor located in the front of the device. Rotation speed and shaking time are pre-set by the user, so that every dilution is processed according to the same protocol (time + speed).

Dilucup

A Dilucup is a small container pre-filled with 9 ml of a sterile diluent. It is available in blisters of seven rows of either three or six containers, designed to fit in the tray of a dedicated “Dilushaker”. The user opens the requested number of Dilucups by tearing-off a thin film that guarantees the sterility and the right volume in the cups.
