LuciPac – Storage Temperatures use

  • Store LuciPac under refrigeration.
  • Allow the LuciPac to come to room temperature before use. Under normal conditions, removing the LuciPac from refrigeration and keeping it at room temperature for about 20 minutes will be sufficient. Using the LuciPac still cold, may cause inaccurate (typically low) readings.
  • LuciPac may be stored in the unopened aluminum bag below 25℃ for up to 14 days or below 30℃ for up to 5 days.

We recommend that you use all 20 swabs in a single bag at the time of opening. If you have unused swabs after opening a bag, you may store them at the recommended low temperature (2-8℃) but these should be used within two weeks from the time the bag is opened.

The stem of the cotton swab of LuciPac must be bent for swabbing.

Consistent pressure when collecting a sample is important as measurement values may vary due to differences in swabbing pressure.

The best way to estimate swab pressure is to look for a consistent bend in the swab.

Recommendations for angle and contact width of cotton swab

  • The swab should be in contact with the surface as shown above (~5mm of contact).

  • This results in a natural swabbing angle of about 10° – 20°.

Collect the sample uniformly!

  • Swab a 10cm x 10cm sampling site both lengthwise and widthwise ten times leaving with no gaps.
  • If it is difficult to use a 10cm x 10cm area for swabbing, you can choose other dimensions, but the swabbing area should be 100cm2.

Uniform swabbing procedure and sampling area

Allow the LuciPac reagent to completely dissolve!

Incomplete mixing of the reagent can cause incorrect measurements.

Keep the Lumitester instrument upright during measurements.

  • If Lumitester is placed sideways, reading errors can occur.
  • Stand Lumitester upright during measurement so that it can read the sample reaction correctly.

Inhibitors of the LuciPac reagent

  • Some disinfectants and sanitizing agents can inhibit the ATP reaction. Sampling should be done before the use of disinfectants or sanitizers.
  • Depending on the concentration of the disinfectants/sanitizers present, interference with the activity of the reagent may occur, resulting in low readings.
  • The table shows some examples:

Handling of LuciPac in hot conditions

  • Use ice packs while transporting LuciPac in a hot environment, such as a car in summer.

  • Do not refrigerate or store the Lumitester instrument in the cooler with reagents. This may cause condensation to form and damage the instrument.
