SU506625A1 - Device for fixing and posting biological micro-objects through intermediate media - Google Patents

Description

Invention; 1; 1e from 0 to the field of microscopic and can be applied in the manufacture of; 1 and micro-preparations from very small biological objects.

A device is known for fixing and posting biological biological objects; croobjects through intermediate media including a container with a filtering plaslin.

The protection of micro-objects from losses in a fast: i FULL c, liquid medium is provided due to the fact that in the LEW device the filter plate is made; in a detachable chamber, connecting with a mechanism for suction and ejection of fluid.

The drawing shows the proposed device, a General view.

EiMKOCTb A device is made in the form of a tube, connect: 1; oh, on the one hand, with a separating filtering chamber B, and, on the other, from the fur: 1; 1mode for suction and ejection and liquids (not shown). The separating filtering chamber B is made of two parts; - the lower one and the upper G, which are interconnected by two oboym / s with a threaded connection.

The device works as follows;

Bottom part Microscopes are placed into the chamber and unscrewed into the chamber. it is necessary to deal with a large mass of airborne organisms, for example, with active sludge,

This chamber can be charged by suction; 1 and water with activated sludge. At the same time, microorganisms are filtered out and remain in the upper filtering part D, and the water goes away: from the tube (tank L). After charging the bottom

The part In the chamber is screwed, and water can be squeezed out from the tube. When out-of-scale devices with micro-objects is a latch; 1 conductive medium, water, as well as uranium impregnation of objects with intermediate media, the liquid is sucked into chamber B and into the tube to a certain level; For a media mixture, the liquid is pushed out by air, the device is transferred to a new liquid, which is again drawn in by the dilution of air in the three-way valve.

If micro-objects clog the pores of the filter plate; then one medium changes to another all the same due to the passage of fluid into the first part of chamber B, where the lower and upper parts of the chamber directly contact one with the other.

Form} l and inventions

A device for fixing and wiring biological micro-objects through intermediate media, including a filter with a filter plate, characterized in that

In order to protect micro-objects from losses during a quick and complete change of liquid medium, the filter plate is made in the form of a detachable chamber connected to a mechanism for suction and ejection of liquid.
