Aia ka pahu helium i ka cylinder non refillable maʻamau, i hoʻolālā ʻia a hana ʻia e like me ke kūlana aupuni GB17268-1998.Hana ʻia ia e ka laina hana i hōʻoia ʻia e ka ʻōnaehana maikaʻi ISO9001-2000 o ka General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China.Aia ia i ka DR4 (i kēia manawa i helu ʻia ʻo B3) huahana cylinder kūikawā o ka ʻāpana kila kila.Hāʻawi ʻia nā cylinders kila i kēlā me kēia ma o ka nānā ʻana i ka hoʻāʻo kaomi.
ʻO ka pahu hau he ipu kaomi no ka mālama ʻana a me ka hoʻopaʻa ʻana i nā kinoea ma luna o ke kaomi lewa.
Ua kapa ʻia nā ʻōmole kinoea kiʻekiʻe he ʻōmole.Aia i loko o ka pahu pahu nā mea i mālama ʻia i loko o ke ʻano o ke kinoea paʻa, ka mahu ma luna o ka wai, ka wai supercritical, a i ʻole i hoʻoheheʻe ʻia i loko o kahi mea substrate, ma muli o ke ʻano kino o nā mea i loko.
Hoʻolālā ʻia ka hoʻolālā pahu kinoea maʻamau, kū pololei ma ka ʻaoʻao lalo palahalaha, me ka valve a kūpono i luna no ka hoʻopili ʻana i ka mea hoʻokipa.
