FOR FAECAL CONCENTRATION OF HELMINTH OVA AND LARVAE / PROTOZOA CYSTS AND OOCYSTS MIXING CHAMBER INTEGRAL SPOON Filter A two stage filtration matrix. 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 50ml centrifuge buckets PARASITOLOGY SINGLE USE IN VITRO DIAGNOSTIC DEVICE Midi Parasep® SELF STANDING SAMPLE CHAMBER

FAECAL PARASITE CONCENTRATOR Q. ■ TJ Q> QJ (A (D ■o Procedure STEP 1 - SAMPLE PREPARATION For empty Parasep®, unscrew lid and add 6.0ml of fixative and one drop of surfactant (eg: Apacor Triton X solution) to the mixing chamber. Alternatively use the reagent ready Midi Parasep®. Introduce a pea sized faecal sample to the fixative. Add 2.0ml of Ethyl Acetate to the mixing chamber. Mix in thoroughly with the Midi Parasep® spoon. If the sample is hard, break it up with the end of the spoon. STEP 3 - CENTRIFUGATION Invert the Midi Parasep® and centrifuge at 1200g for three minutes. Midi Parasep®...
