Abderhalden's drying pistol is a piece of laboratory glassware used to free samples from traces of water, or other impurities. It is called a "pistol" because of its resemblance to the firearm. Its use has declined due to modern hotplate technology and vacuum pumps.

Дык в том-то и загадка, с какой концентрации. Вроде и работе не мешает, а влага уходит на 2-3 сутки. Без мануала на засыпку ничего не поймешь.

Цеолиты - одни из самых сильных осушителей, после них остаются только следы воды. Таблица из книги П.И. Воскресенский Техника лабораторных работ viewtopic.php?p=1918#p1918 Attachment: 038_0001.jpg [ 185.19 KiB \| Viewed 2780 times ] Цеолиты лучше силикагеля, но хуже пятиокиси фосфора (фосфорный ангидрид). Недостаток цеолитов - низкая емкость (количество влаги, которое они способны поглотить).
