Description

Известно вакуумное устройство дл  вырезани  лунок в агаре при титровании антибиотиков методом диффузии в агаре, состо щее из пробочного сверла, промежуточного стекл нного сборника агаровых вырезок и вакуумного насоса. Недостатком устройства  вл етс  необходимость точной регулировки остаточного давлени , так как слишком сильный вакуум разрывает агар, а слабый не вт гивает блоки в промежуточный сборник.A vacuum device for cutting holes in agar during the titration of antibiotics by diffusion in agar, consisting of a cork drill, an intermediate glass collection of agar slices and a vacuum pump, is known. The drawback of the device is the need for precise adjustment of the residual pressure, because too much vacuum breaks the agar, and the weak one does not pull the blocks into the intermediate collector.

Предлагаемое устройство дл  изготовлени  лунок в агаре при диффузионном методе анализа просто в изготовлении и эксплуатации, повышает производительность труда и чувствительность метода диффузионного анализа. Это достигаетс  выполнением устройства в виде пустотелого цилиндра, отличительной особенностью которого  вл етс  наличие пропила вдоль оси симметрии цилиндра, расшир юш,егос  руко тке, что позвол ет использовать принцип механического вырезани , зажима и удалени  вырезанного агара посредством уменьшени  диаметра рабочей части.The proposed device for the manufacture of wells in agar with the diffusion method of analysis is simple to manufacture and operate, increases the productivity and sensitivity of the method of diffusion analysis. This is achieved by making the device in the form of a hollow cylinder, a distinctive feature of which is the presence of a kerf along the axis of symmetry of the cylinder, extending its handle, which allows the principle of mechanical cutting, clamping and removing the cut agar to be used by reducing the diameter of the working part.

На фиг. 1 представлено устройство дл  изготовлени  лунок в агаре; на фиг. 2 - устройство в разрезе, вид сбоку. Устройство дл  изготовлени  лунок в агаре пр.и диффузионном методе анализа представл ет собой оолый цилиндр /, состо щий из руко тки 2 (широка  часть цилиндра, выполн юща  также роль сборника извлекаемых из лунок агаровых вырезок) и рабочей части 3, суженной до диаметра нужной величины лунок. Цилиндр расп лен вдоль оси симметрии почти по всей длине, что обеспечивает некоторую подвижность обеих половин устройFIG. 1 shows a device for making wells in agar; in fig. 2 - the device in a section, side view. The device for the manufacture of wells in agar, the diffusion method of analysis, is a hollow cylinder (consisting of a handle 2 (wide part of the cylinder, also playing the role of a collection of agar cuts extracted from the holes) and the working part 3, narrowed to the desired diameter). hole sizes. The cylinder is distributed along the axis of symmetry almost along its entire length, which provides some mobility for both halves of the device.
