FOR FAECAL CONCENTRATION OF HELMINTH OVA AND LARVAE / PROTOZOA CYSTS AND OOCYSTS MIXING CHAMBER INTEGRAL SPOON Filter A triple stage matrix filtration. Large particles are rejected without obscuring filtration. Recovery rate with Parasep® is comparable to traditional sieve method, ie: Ridley-Allen. The vertical filter enclosed design is patented. Debris Trap Rejected particles are trapped to prevent extrusion into the Sedimentation Cone during centrifugation. Air/Liquid Seal and Safety Lock The ‘seal’ prevents the release of biohazardous material. The ‘lock’ ensures the Mixing Chamber and Filter are removed together for safe disposal. Sedimentation Cone Sediment forms in the base of the cone allowing examination for the presence of helminth eggs or larvae and protozoa cysts or oocysts. Health and Safety Benefits • Totally enclosed/sealed process • Reduced reagent volumes • No cleaning required • Single use, no sample contamination • Ready to use systems available Performance Benefits • Optimum sample recovery • Enhanced sample clarity • Rapid four step process • Human resources optimised • Easy patient identification • Fits all 15ml centrifuge buckets PARASITOLOGY SINGLE USE IN VITRO DIAGNOSTIC DEVICE SELF STANDING SAMPLE CHAMBER

Procedure STEP 2 - EMULSIFICATION Seal the Mini Parasep® SF by screwing in the filter/ sedimentation cone unit. FAECAL PARASITE CONCENTRATOR STEP 1 - SAMPLE PREPARATION Fresh Samples For empty Parasep®, unscrew lid and add 3.3ml of fixative and one drop of surfactant (eg: Apacor Triton X solution) to the mixing chamber. Vortex or shake to emulsify with the sedimentation cone pointing upwards. Alternatively use the reagent ready Mini Parasep® SF. Introduce a level scoop of faecal sample to the fixative using the spoon on the end of the Mini Parasep® SF filter. Mix in thoroughly with the Mini Parasep®...
