[Product Code]



50 mL/vial, 40 vial/case


This product is used to dilute and liquefy the samples to be tested. Sputum is highly viscous and inconvenient for direct testing. So in clinical practice, sputum samples need liquefaction before testing to release mucin and to reduce the viscosity of the sputum. This product mainly uses substances containing sulfhydryl (-SH) to break the main components of mucin in sputum that causes viscosity, thereby reducing the viscosity of sputum and liquefying sputum.
