Isihluzo sesirinji sisixhobo esincinci, esilahlwayo esiqhele ukusetyenziswa kwizicwangciso zelabhoratri ukuhluza okanye ukucacisa ulwelo. Yenzelwe ukuba ifakwe ekupheleni kwesirinji kwaye isebenze njengesithintelo esisusa amaqhekeza kunye nokungcola kumanzi njengoko kunyanzeliswa ngesihlunu.
Izihluzi zesirinji zikholisa ukuba nendlu yeplastiki enesihluzo senwebu ngaphakathi. Indlu inesitshixo se-luer wesifazane okanye uqhagamshelo lwe-luer slip oluvumela ukuba luncanyathiselwe ngokukhuselekileyo kwisirinji. I-membrane filter, eyona nto ibalulekileyo, yenziwe ngesixhobo esinemingxuma esivumela ulwelo ukuba ludlule ngelixa igcina amasuntswana kunye nezinto ezingcolisayo ngaphezu kobukhulu obuthile.
