GUSHYIRA MU BIKORWA
Kuva isahani ya reagent ivumburwa mu 1951, byabaye ngombwa mubisabwa byinshi; harimo kwisuzumisha kwa kliniki, ibinyabuzima bya molekuline na biologiya selile, ndetse no gusesengura ibiryo na farumasi. Akamaro k'isahani ya reagent ntigomba gusobanurwa kuko ubushakashatsi bwa siyansi bwa vuba burimo kwinjizamo ibicuruzwa byinshi bisa nkaho bidashoboka.
Byakoreshejwe muburyo butandukanye bukoreshwa mubuvuzi, amasomo, imiti nubuvuzi, ibyo byapa byubatswe hakoreshejwe plastiki imwe. Ibisobanuro, bimaze gukoreshwa, bipakirwa hanyuma byoherezwa ahajugunywe imyanda cyangwa bikajugunywa no gutwikwa - akenshi nta kongera ingufu. Aya masahani iyo yoherejwe mu myanda agira uruhare muri toni zigera kuri miliyoni 5.5 z’imyanda ya laboratoire ikorwa buri mwaka. Mugihe umwanda wa plastike ugenda uba ikibazo cyisi yose yo guhangayikishwa cyane, bitera kwibaza - isahani ya reagent yarangiye ishobora gutabwa muburyo bwangiza ibidukikije?
Turaganira niba dushobora kongera gukoresha no gutunganya ibyapa bya reagent, kandi tugashakisha bimwe mubibazo bifitanye isano.
NIKI CYEREKEZO CYA REAGENT YAKOREWE?
Isahani ya reagent ikorwa muri thermoplastique, polipropilene. Polypropilene ikwiranye na plastiki ya laboratoire bitewe n'ibiranga - bihendutse, biremereye, biramba, ibikoresho bifite ubushyuhe butandukanye. Nibisanzwe kandi bikomeye, byoroshye kandi byoroshye, kandi mubitekerezo biroroshye kujugunya. Birashobora kandi gukorwa muri Polystirene nibindi bikoresho.
Nyamara, polypropilene hamwe n’ibindi bikoresho bya plastiki birimo Polystirene byakozwe mu rwego rwo kurinda isi kamere kutangirika no gukoreshwa cyane, ubu bitera impungenge nyinshi z’ibidukikije. Iyi ngingo yibanze ku masahani yakozwe muri Polypropilene.
KUGARAGAZA AHO BASANZWE
Amasahani ya reagent yarangiye avuye muri laboratoire yigenga n’abikorera ku giti cyabo yo mu Bwongereza ajugunywa muri bumwe mu buryo bubiri. Bashobora 'gupakirwa' no koherezwa mu myanda, cyangwa barashya. Ubu buryo bwombi bwangiza ibidukikije.
