Haufinyane tjena, litaba tsa "blockbuster Claim for High-Price Washers for Bottle Washers" li tsositse maikutlo a atileng a sechaba.Pale e tjena:

Mohlatsoana oa nakoana oa botlolo Mofumahali Zhou, e motšehali, o lilemo tse fetang 40.O hiriloe ka Mots'eanong nako e ka tlase ho likhoeli tse 'maloa laboratoring e nang le setsi sa tlhahlobo sa mokha oa boraro ka leboea ho China.Mofumahali Zhou o ikarabella bakeng sa ho hloekisa lisebelisoa tsa khalase tse kang tube ea teko, pipette, beaker le senoelo sa ho metha ka laboratoring.Ha a ntse a hlatsoa, ​​​​ka lebaka la tšenyo e setseng ea lik'hemik'hale ka har'a khalase, sefahleho sa hae, matsoho le likarolo tse ling tsa 'mele li ile tsa tsoa likotsi tse mpe.Nyeoe ena e amohetsoe ke mafapha a amehang.

Mofumahali Zhou o ile a bolella mecha ea litaba hore tsamaiso ea ka hare ea laboratori e sa tsoa thehoa ha ea phethahala, 'me ha a e-s'o fumane koetliso e lekaneng ea pele ho mosebetsi.Haholo-holo ha ho phekoloa lintho tse setseng tsa lik'hemik'hale ka mor'a teko, ha lia ka tsa tsebisoa ka tekanyo ea kotsi ea li-reagents, lisebelisoa tsa tšireletso le mekhoa ea tšireletso.

Ho feta moo, mosebetsi oa ho hloekisa lisebelisoa ka laboratoring ena o boima haholo matsatsing a beke, athe bohloeki ba lisebelisoa tsa khalase ka laboratoring bo phahame haholo.Leha ho le joalo, sephetho sa ho hlatsoa ka matsoho hangata se hloleha ho kopana le maemo a ikemetseng a laboratori, kahoo ke tlameha ho sebetsa nako e eketsehileng bakeng sa ho sebetsa hape. Ntlha ena e tla ba tletlebo e arohaneng le lefapha la basebetsi la lehae.

Mofumahali Zhou ka tlhahlobo ea likotsi tsa inductrial o ile a lahleheloa ke bokhoni ba mosebetsi o itseng.Ho ea ka sena, ke kopa laboratori ho lefella litšenyehelo tsa bongaka, litšenyehelo tsa mosebetsi tse lahlehileng, litšenyehelo tsa lipalangoang, joalo-joalo, kakaretso ea li-yuan tse fetang limilione tse 1. Ho latela nyeoe ho ntse ho tsoela pele.

Ha e le hantle, ho na le li-reagents tse ngata tsa lik'hemik'hale ka laboratoring tse tla baka likarolo tse fapaneng tsa tšenyo 'meleng oa motho.Haeba laboratori e sa nke mehato e lekaneng ea ho itšireletsa khahlanong le basebetsi, 'me e hlokomoloha ho hloekisa lisebelisoa tsa laboratori, e ka baka litlamorao tse mpe joalo ka ts'usumetso, kholofalo le mofets'e ho basebetsi. Hangata basebetsi ba laboratori ba pepesehetse.
