Hoʻohana pinepine ʻia nā mea hoʻokomo vial i loko o nā laboratories e hana ana me ka liʻiliʻi o nā laʻana. Mālama nā mea hoʻokomo i nā laʻana i loko o kahi leo liʻiliʻi a maʻalahi ka unuhi ʻana i ka hāpana mai ka hue no ka nānā ʻana.
He kino ākea ka ipu conical akā he ʻāʻī haiki, e hōʻemi ana i ka hiki ke kahe i ka wā o kēia kaʻina wili. He mea koʻikoʻi kēia inā loaʻa nā waikawa ikaika. ʻO ka ʻāʻī haiki hoʻi e maʻalahi ka ʻohi ʻana i ka ipu conical, ʻoiai ʻo ke kumu pālahalaha e hiki ai ke kau ʻia ma luna o kekahi ʻili.
Hoʻohana ʻia ka ipu volumetric i ka wā e pono ai ke ʻike pololei a pololei i ka leo o ka hopena e hoʻomākaukau ʻia nei. E like me nā pipets volumetric, hele mai nā pahu volumetric i nā nui like ʻole, ma muli o ka nui o ka hopena e hoʻomākaukau ʻia.
ʻO ka ipu wai PTFE mānoanoa, kūpaʻa wela kiʻekiʻe, kūpaʻa ka ʻakika a me ka alkali, nozzle diversion, poʻe lalo 50/100/150/200/250/500/1000/2000/3000ml.
