Hoʻomaopopo mākou i ke koʻikoʻi o ka pale ʻana i ka pono o kāu biomolecules a me nā reagents me nā ʻōnaehana buffering kūpono.Hāʻawi kā mākou mea hoʻolale ola i ka paʻa o ka hoʻonā a me ka mālama pH me ka ʻole o ka hoʻopili ʻana i nā kaʻina hana olaola, a hāʻawi i nā paʻakai koʻikoʻi a me nā meaʻai no nā cell a me nā ʻiʻo.Hiki i kā mākou ʻōnaehana hoʻopaʻa kiʻekiʻe ke hāʻawi iā ʻoe i ke kūpaʻa kupaianaha i ka moʻomeheu cell, polymerase chain reaction (PCR), ka nānā ʻana i ka lāʻau lapaʻau, bioprocessing, hoʻomaʻemaʻe, a me nā noi hoʻoponopono hope.Hiki ke hoʻonui ʻia kā mākou huahana a pau mai ka noiʻi mua ʻana i nā noi pāʻoihana ma nā māka buffer like ʻole.Hāʻawi mākou i nā hoʻonohonoho hoʻopihapiha he nui, ka hui ʻana maʻamau, a me ka hoʻoheheʻe wai.
