Trattar
Trattar underlättar överföring av vätskor eller pulver till behållare. De har vanligtvis en bred öppning som leder materialen genom den smala halsen, vilket förhindrar spill och håller arbetsytan ren. Trattar finns i specialiserade utföranden för olika laboratorietillämpningar. Många modeller är kompatibla med filterpapper eller glasfritter vid filtrering. Tack vare förmågan att kanalisera både finfördelade och flytande material är trattar oumbärliga verktyg i alla miljöer.
