Byrety
Byrety jsou zařízení používaná obvykle v analytické a kvantitativní chemii k měření objemu kapalných roztoků nebo plynů. Na rozdíl od pipety, protože množství dodaného vzorku je proměnlivé, se stupnicové byrety hojně používají v titračních experimentech. U metod měření kapaliny na spodní části menisku je kohoutek zabraňující úniku umístěn na dně svislé skleněné trubice, zatímco u modelů pro plyny se nachází nahoře. Pro nejpřesnější odečty jsou k dispozici digitální varianty.
