ʻO ka WD-9402M Gradient PCR Instrument kahi mea hoʻonui gene i loaʻa mai kahi mea hana PCR maʻamau me ka hana hoʻohui o kahi gradient. Hoʻohana nui ʻia ia i ka molecular biology, lāʻau lapaʻau, ʻoihana meaʻai, hoʻāʻo gene, a me nā ʻano ʻē aʻe.
ʻO WD-9402D thermal cycler he mea hana keʻena hana i hoʻohana ʻia i ka biology molecular e hoʻonui i ka DNA a i ʻole RNA sequences ma o ka polymerase chain reaction (PCR). ʻIke ʻia ʻo ia he mīkini PCR a i ʻole DNA amplifier. WD-9402D he 10.1-inihi kala paʻi paʻi, e maʻalahi ka hoʻomalu ʻana, hāʻawi iā ʻoe i ke kūʻokoʻa e hoʻolālā a hoʻouka paʻa i kāu mau ala mai kekahi mea kelepona a i ʻole kamepiula papapihi.
