Description

диаметра эластичного шланга 5 и возможной длины прокатываемого участка.the diameter of the elastic hose 5 and the possible length of the rolled section.

Основные преимущества пипетки-наполнител  перед существующими это удобство пользовани , быстра  смена стекл нных пипеток и герметичное жесткое их закрепление.The main advantages of the pipette-filler over the existing ones are ease of use, quick change of glass pipettes and their tight tight fixation.

Кроме описанной функции - отбор пробы в стекл нную пипетку 7 и дозирование по ее делени м - можно осуществл ть дозирование капл ми, дл  чего вместо стекл нной пипетки 7 в цанговый зажим 8 вставл етс  переходна  втулка 1 со стандартным сменным наконечником 13 от автоматических пипеток (см. фиг. 2). Забор жидкостей в сменный наконечник 13 и вытеснение ее до образовани  и отрыва капли производитс  как описано выше .In addition to the described function — taking a sample into a glass pipette 7 and dosing according to its division — drops can be dosed, for which instead of a glass pipette 7 a transition sleeve 1 with a standard interchangeable tip 13 from automatic pipettes is inserted into collet 8 ( see Fig. 2). The collection of liquids into the interchangeable tip 13 and its displacement before the formation and separation of the droplet is carried out as described above.
