Cov hniav ntawm ib qho zoo tagnrho microtome yuav tsum tsim ib txoj kab ncaj nraim ntawm ob lub tiaj tiaj. Lub microtome ntse tuaj yeem txiav cov paraffin hlais mus rau 2 microns thiab tsis tu ncua tsis muaj compression. Yog hais tias cov hniav yog tuab dua li ntawm tes, nws yuav ua rau muaj kev puas tsuaj rau lub cell ntau dua li kev txiav. Yog li ntawd, sharpening yog ib qho kev txawj ntse hauv slicing technology thiab yuav tsum tau xyaum thiab txawj.
Muaj ntau hom kev sib tsoo pob zeb; ntuj, dag lossis tiaj tus iav. Ntuj sib tsoo pob zeb: Nws yog ib advisable kom ua tib zoo xaiv inkstone pob zeb nrog ntshiab kev ntxhib los mos, tsis muaj impurities thiab kuj nyuaj. Me ntsis mos thiab astringent sawv daws yuav siv rau " ntxhib sib tsoo"; tawv thiab du yog siv rau "zoo sib tsoo".
Muaj pob zeb diamond sib tsoo pob zeb; muaj ntau yam specifications thiab qib, thiab cov fineness yog uniform. Feem ntau, cov xuab zeb zoo tshaj plaws yog siv rau "kev sib tsoo ntxhib" hauv histology kom zom cov qhov khoob loj ntawm cov hniav ntawm cov microtomes uas raug mob hnyav.
Flat iav: Txiav rau qhov loj me rau kev sib tsoo pob zeb, thiab ntxiv cov abrasives xws li txhuas oxide rau cov pob zeb sib tsoo. Siv tib yam li cov pob zeb sib tsoo zoo tib yam. Qhov kom zoo dua yog tias koj tuaj yeem hloov cov hmoov sib tsoo los yog slurry ntawm qhov sib txawv fineness, thiab siv rau "coarse sib tsoo", "medium sib tsoo" los yog "zoo sib tsoo" ntawm lub khob phaj.
Qhov luaj li cas ntawm cov pob zeb tuaj yeem sib txawv raws li qhov loj thiab hom ntawm lub tshuab txiav. Thaum sharpening riam, ntxiv dilute lubricating roj, soapy dej los yog dej. Roj zoo dua. Tom qab siv lub grindstone, so tawm cov abrasive thiab me me hlau chips. Nws yog qhov zoo tshaj plaws los kho cov pob zeb hauv ib lub thawv nrog grooves nyob ib ncig ntawm lub pob zeb kom ntws cov roj thiab dej ntau dhau. Npog lub thawv npog tam sim tom qab siv los tiv thaiv cov av los yog plua plav los ntawm nws. Yog tias cov plua plav no tsis raug tshem tawm, nws yuav ua rau lub pob zeb puas thiab ua rau cov hniav tsis zoo thaum sib tsoo.
