Introduction
The document introduces Sigma SP™, a mucolytic solution designed for the preparation and processing of sputum specimens. It highlights the challenges associated with sputum due to its varying viscosity and purulence and presents Sigma SP™ as a solution to these issues.

Specifications
Sigma SP™ is a powerful mucolytic reagent that is ready to use in a liquid format. It is designed for both automated and manual processing of sputum specimens. The solution has a neutral pH and can be stored at ambient temperature for extended periods.

Procedures
To use Sigma SP™, add 1ml of sputum to the vial, replace the cap, vortex, and allow it to stand at room temperature for 15 minutes. The sample is then ready for processing.

Advantages
The solution is not harmful to target bacteria, allowing specimens to remain in processing queues for hours without compromising pathogen survival. It is compatible with molecular diagnostic test systems and is particularly suited for automated processing platforms.

Order Information
Sigma SP™ is available in a 1ml fill volume, packaged in sets of 50. It is covered under UK patent application number 1705662.3.
