Description

Plate counting device for chemical residue cleaning verification

Technical Field

The utility model belongs to the technical field of chemistry experiment equipment, concretely relates to a some board ware that is used for chemistry to remain clean verification.

Background

In chemical residue cleaning and chemical verification of medicines, in order to detect whether the active medicine residue on the surface of equipment in direct contact with medicines meets the requirement after the production equipment of the medicines is cleaned so as to ensure that the equipment does not cause cross contamination to the production of the next batch of products and the products of public equipment thereof after being used and ensure the quality of the products, cotton swab wiping is usually carried out on the surface of the equipment in direct contact with the medicines for sampling detection, and in order to prove that the used detection method is suitable for the detection of the residual quantity of effective components in the cleaning verification and provide effective and stable data for the chemical residue cleaning verification, the process of wiping the cotton swab on the surface of the equipment needs to be simulated, a sample of the cotton swab is taken for detection, and the wiping recovery rate is calculated and is used as a parameter for calculating the concentration of the sample in actual detection. However, in the simulation process, the control product needs to be subjected to plate spotting operation in advance, the conventional plate spotting operation adopts a pipette, and in order to spot a certain volume of control product solution on a plane with a fixed area, not only the right-hand index finger is needed to control the liquid discharge speed in the pipette, but also the left hand is needed to stably hold the lower part of the pipette, so that the plate spotting is repeated for hundreds of times, the time and labor consumption are high, the speed is not easy to control, and the efficiency is low.

SUMMERY OF THE UTILITY MODEL

To the problem that wastes time and energy, inefficiency that exists among the prior art, the utility model aims to provide a point board ware that is used for chemistry to remain clean verification that labour saving and time saving, efficient. The method is realized by the following technical scheme:

a some board ware for chemistry remains clean verification, including the plastics cup that the components of a whole that can function independently set up and stainless steel's sample application container, the lower surface of container is provided with the sample application pipe subassembly that is used for the reference substance solution to ooze, the upper surface of container is provided with the installation department that is used for the plastics cup to connect.

Furthermore, the container is cubic, the installation department sets up the middle part position at the container upper surface, is a circular opening of protrusion container upper surface, the surface of installation department is provided with the external screw thread, be provided with the internal thread that uses with the external screw thread cooperation on the plastic cup.

Further, the sampling tube assembly comprises a conical tube and a ball, wherein the conical tube and the ball are integrally arranged on the lower surface of the container, one end, far away from the container, of the conical tube is a liquid leakage opening, and the liquid leakage opening of the conical tube is arranged in the ball.

Further, the opening diameter of the leakage port is smaller than the diameter of the ball. The arrangement ensures that the ball bearing partially protrudes out of the liquid leakage opening and completely blocks the liquid leakage opening under the natural state of the plate counting device.

Further, the conical tubes are arranged in a plurality of rectangular arrays and distributed on the lower surface of the container, and the number of the balls corresponds to that of the conical tubes.

Furthermore, the plastic cup is provided with scale marks, so that liquid with a fixed volume can be conveniently measured, and a quantitative counting plate is realized.

The utility model discloses structural design is simple, the practicality is strong, only needs to press the container upper surface during the application of sample, and the ball moves up and makes the weeping mouth leave the gap, realizes that the effective component of fixed area can once be come out to the conical tube on the board ware of some, and this point board operation, labour saving and time saving is efficient.

Detailed Description

The invention will be further described with reference to the accompanying drawings for better understanding of the technical solution.

As shown in fig. 1-2, the utility model relates to a point trigger for chemistry remains clean verification, the point trigger of mainly used simulation chemistry when remaining clean verification, in order to obtain accurate rate of recovery, as the parameter that sample concentration calculates among the actual detection, its concrete structure includes plastic cup 1 and the sample application container 2 of stainless steel that the components of a whole that can function independently set up, wherein, plastic cup 1's rim of a cup has the internal thread, container 2's upper surface is provided with the installation department 3 with plastic cup 1 threaded connection, installation department 3 is the circular opening of protrusion container upper surface, be provided with external screw thread 4 on it, this setting is convenient for the splendid attire of control solution in earlier stage, and simultaneously, still be provided with scale mark 6 on plastic cup 1's the wall, be convenient for the definite of control solution volume.

Continuing to refer to fig. 1-2, in order to realize quick and convenient sample application operation, be provided with the sample application pipe subassembly that is used for the reference solution to ooze at the lower surface of container 2, this sample application pipe subassembly includes that the integral type sets up a plurality of conical tubes 5 and the ball of stainless steel that are the setting of rectangle array on the lower surface of container, the sign is not seen in the ball picture, the one end that container 2 was kept away from to conical tube 5 is the weeping mouth, place conical tube 5 weeping mouth department in the ball, and the opening diameter of weeping mouth is less than the diameter of ball, realize under natural state, the ball can block up the weeping mouth completely.
