MicroSwab: A MicroSwab consists of a lyophilized pellet of a single microorganism strain inside a pen-like device. This pen-like device contains a sterile swab and rehydration fluid to facilitate the transfer of the microorganisms directly to culture media. The pellet has no defined CFU assay but a minimum of 1000CFU/pellet to ensure proper growth. Use MicroSwabs whenever a defined assay value is not needed. The MicroSwabs are up to 4 passages removed from reference strain.

A practical source for microorganisms.

The MicroSwab show several advantages, which make them a great source for ATCC®∗ derivatives, if defined assay value is not required.

  • Each lyophilized preparation is less than or equal to 4 passages from a reference culture.
  • The pen-like MicroSwabs are easy to use.
  • They can be stored at 2-8°C.
  • MicroSwabs expire 12-24 months after production.
  • More than 400 different strains are available, tracable to authentic ATCC®∗ reference cultures.
  • MicroSwabs are sold in economical units of two.
  • A certificate of analysis for your QM documentation is included.

MicroSwabs - there's no easier way!

  • Do you know other products similar to ours? Then you may be aware of the following problems:
  • some products also have a container of rehydration fluid inside a pen-like device. However this container is made of glass; you have to apply a substantial amount of pressure to break it in order to rehydrate the lyophilized pellet.
  • Other lyophilized preparations have to be pinched a homogenous suspension with the rehydration fluid.
  • Our MicroSwabs are easy to handle. And this for the following reasons:
  • With the following simple actions you have inoculated your culture media.

Our MicroSwabs are easy to use.

With the following simple actions you have inoculated your culture media.


Break the red "snap" valve by bending to a 45° angle.


Gently squeeze cap until all fluid moistens the lyophilized pellet in the bottom of the tube.


Gently shake so swab absorb rehydrated pellet.


Remove cap from tube and inoculate media.
