Abstract
The utility model relates to an automatic cleaner for the calibrated pipet. A reverse U-shaped siphon is positioned in the cleaning tank, one end of the U-shaped siphon is in the tank, the other end is out of the tank. The U-shaped siphon is not arranged symmetrically, the longer end is out of the tank, a perforated partition board is arranged at the lower part of the cleaning tank, the cleaning tank is arranged in the ultrasonic cleaner. The bottom of the cleaning tank is connected with the ultrasonic cleaner. The utility model can individually adopt the cleaning tank to clean and has the function of automatic operation and fulfillment; also, the utility model can work with the ultrasonic cleaner so as to reach the purpose of further improving the cleanness degree and the cleaning efficiency of the calibrated pipet.
Description
Technical field
The utility model relates to a kind of cleaning equipment, relates in particular to a kind of employing siphon principle, can reach automatic cleaning purpose, is specially adapted to the automatic cleaning machine that measuring pipette cleans.
Background technology
The laboratory of R﹠D institution, the hospital laboratory, the factory laboratory, big-and-middle universities and colleges laboratory, the unit of grade of check institute all will use measuring pipette when testing.Measuring pipette is can reusable reflex glass suction pipe, plurality of specifications such as 0.1ml-10.0ml is arranged, every price comparison costliness.Test how cleaning treatment of used measuring pipette, to reach the purpose of using repeatedly? up to the present, artificial cleaning is all adopted in each laboratory, one one clear water flushing of drawing earlier, drain, concentrate and put into the immersion of potassium bichromate cleaning solution 4-6 hour or crossed liquid, and then one one clear water of drawing is rinsed well, clean dry for standby again with distilled water.Its deficiency is that cleaning efficiency is low, and the very difficult assurance of cleaning quality, and is particularly thinner as small dimension measuring pipette endoporus such as 0.1ml, 0.2ml, water is not easy to enter in the suction pipe very much, it is unclean to cause suction pipe to be handled, and might cause experimental data inaccurate, the data poor repeatability occurs.
Summary of the invention
The utility model mainly is to solve the low problem of existing in prior technology measuring pipette cleaning efficiency, thereby develops a kind of measuring pipette automatic cleaning machine.
Another purpose of the present utility model is a kind of measuring pipette automatic cleaning machine that can guarantee as small dimension measuring pipette cleaning qualities such as 0.1ml, 0.2ml of exploitation.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of measuring pipette automatic cleaning machine, has washing bucket, it is characterized in that: described washing bucket is built-in with an end and is positioned at bucket, and the other end is positioned at the outer inverted U-shaped siphon pipe of bucket; The asymmetric setting of described siphonal U-shaped, its long end is positioned at outside the bucket.Described siphon pipe one end is in washing bucket, and the other end passes from the washing bucket top and is placed on outside the bucket.Also can the other end be passed outside the bucket.
Technique scheme of the present utility model can also be further perfect, and as preferably, the dividing plate in thread hole is arranged at the bottom of described washing bucket.Described thread orifice plate can adopt metal or engineering plastics or nylon products, is arranged at from a distance, staving bottom, and the diameter of its thread hole or grid should be less than the measuring pipette diameter, and the shape of its plate is generally with the washing bucket internal diameter and adapts.The dividing plate location can add anchor point at the washing bucket inwall, also can backstay be set at the dividing plate bottom surface.
As preferably, described siphon pipe is positioned at the end excurvation of the outer end of washing bucket bucket.It is smooth and easy that the end excurvation helps water outlet.
As preferably, described washing bucket is arranged in the supersonic wave cleaning machine, and described washing bucket bottom is connected with the transducer of supersonic wave cleaning machine.Washing bucket matches with ultrasonic cleaner, can utilize action of ultrasonic waves to play and improve the effect that measuring pipette cleans cleanliness factor and cleaning efficiency.
As preferably, described washing bucket and/or siphon pipe adopt metal material.Adopt metal material such as stainless steel and so on, have long-life advantage, but cost is higher.Also can adopt glass or plastic products as required with possible.
Therefore, the utility model utilizes washing bucket can reach from moving water, to improve wash degree; Utilize action of ultrasonic waves again, further improve the effect that measuring pipette cleans cleanliness factor and cleaning efficiency.Make cleaning carry out automatically, finish automatically, use very conveniently, improved cleaning efficiency greatly, guarantee cleaning quality.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of working state schematic representations of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
As shown in Figure 1, washing bucket 1 of the present utility model is circular, is made by metal, also can adopt glassware or plastic products.Be provided with the dividing plate or the waffle slab 4 in thread hole in the washing bucket 1, the utility model adopts diameter to be slightly less than the thread hole dividing plate of washing bucket internal diameter, and the aperture is slightly less than the suction pipe diameter, and described dividing plate is with a certain distance from the bottom, and separator material generally adopts metal, as stainless steel.Be provided with siphon pipe 2 in the washing bucket, described siphon pipe adopts metal to make, one end places the bucket bottom in the washing bucket, the other end passes a barrel wall and places outside the bucket, also can be outside bung place bucket, it is inner that the outer port of export of its barrel is lower than bucket, and form elbow 6, to make things convenient for water outlet, also can adopt straight tube according to the water outlet situation.Described washing bucket 1 can utilize siphonal siphon principle to use separately, also can place in the supersonic wave cleaning machine, and the washing bucket bottom is connected with the transducer of supersonic wave cleaning machine.Washing bucket matches with ultrasonic cleaner, can utilize action of ultrasonic waves to play and improve the effect that measuring pipette cleans cleanliness factor and cleaning efficiency.
During use, as shown in Figure 2, the measuring pipette 3 that needs clean is put into washing bucket 1, and running water slowly flows in the washing bucket, opens the power supply of ultrasonic cleaner, water slowly rises to siphon pipe 2 tops at the bottom of bucket, washing bucket in comprise that the water that enters measuring pipette in immediately by siphon flowed away because siphonage this moment, wait the complete siphon of water in the bucket intact after, advanced air in the siphon pipe, current stop.At this moment, because running water is flowing always, the water in the bucket rises from the bottom again, carries out so repeatedly.After cleaning end, close running water, powered-down gets final product.
The whole cleaning process of measuring pipette is: the suction pipe that will test with mistake drains with the running water flushing earlier, putting into the potassium bichromate cleaning solution soaked 4-6 hour, concentrate then and put into washing bucket, running water slowly flows in the bucket, tap one is heading straight for, open the power supply of ultrasonic cleaner, just flushing automatically in bucket of suction pipe is approximately turned off power supply and water tap after 30-60 minute.Put into washing bucket with distilled water again and take out from washing bucket after three times repeatedly, it is standby that suction pipe is put into the baking box 100 following oven dry of degree strength.
