Planti taim, i no gat nid long klinim ol nupela glas o 'ceramic beads' yu baim. Dispela i kamap bikos taim ol i nupela, ol i gat 'carbon black' tasol, we i no save wok na i no inap long bagarapim ol wok painimaut bilong yu. Na tu, ol i save rausim kabon blak hariap long rot bilong 'centrifugation' o 'filtration' bihain long ol i brukim. Tingim, noken yusim asid long klinim ol bis. Noken mekim olsem, putim ol 'beads' insait long 'laboratory detergent' long nait, wasim wantaim wara bilong paip long rausim olgeta 'detergent', na bihain wasim wantaim wara we i no gat marasin long en. Putim ol 'beads' we yu wasim pinis antap long wanpela 'stainless steel' o 'glass tray' na draim ol insait long wanpela aven long 40-70 digri.
Gaid bilong baim samting:
1. Long ol baktiria, mipela i rekomendim yusim ol glas bis we i gat diamita bilong 0.1 mm.
2. Long ol yis/fungi, yusim ol glas bis wantaim diamita bilong 0.5 mm.
3. Long ol 'tissue block', yusim ol 'beads' we i gat diamita bilong 1.0 mm.
4. Long skin na ol 'tissue' bilong diwai, yusim ol 'beads' we diamita bilong en em 2.5 mm.
5. Long praktis, ol risetsa i save makim ol 'beads' we i klostu long sais bilong ol 'sample particles' na i gat bikpela 'density'. Olsem, ol i save yusim 0.1mm zirconia-silica bis long bagarapim ol 'spores'; Ol i save yusim 2.5mm 'zirconia' o 'stainless steel' bis long bagarapim ol 'fibrous tissue' bilong diwai.
6. Pastaim wok painimaut bilong mipela i soim olsem yusim ol 'angular beads' na i no ol 'round beads' em i gutpela long bagarapim ol 'tissues' bilong ol diwai na animal.
