Abstract

The utility model relates to a liquid automatic balancing centrifuge used in medical, chemical, etc. laboratories for separating blood sample or when the centrifugal settling chemical experiment is done, and comprises a motor and a centrifugal rotating device installed on the output axis of the motor; the centrifugal rotating device comprises a bucket for holding a test tube to be centrifuged, pistons and piston chambers which are arranged under the bucket, and connecting pipes for connecting each piston chamber, wherein, soft bags with good elasticity can be laid into each piston chamber, and the soft bags can be communicated through connecting pipes; two openings are also opened on the soft bags, and a cap is installed on each opening; the utility model has the advantages that the balancing is automatic, the labor force can be saved, the cost is low, the operation is convenient, the performance is safe and reliable, and the service life is long.

Description

The automatic balance of liquid centrifuge

Technical field

The utility model relate to a kind of in laboratories such as medical science, chemical industry separating blood sample or the automatic balance of liquid centrifuge that uses when doing the centrifugation chemical test.

Background technology

At present, when in laboratories such as medical science, chemical industry, using centrifuge to make the separating blood sample or do the centrifugation chemical test, each must be manually before centrifugal with the another one test tube or add the water counterweight, make centrifuge both sides balance, balance phenomenon just can not take place in centrifuge in the running like this.This preparatory work not only complexity but also inconvenience when each experiment is started shooting, the shortcoming that existing wastes time and energy takes a lot of work.

Summary of the invention

The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of can automatic trim, time saving and energy saving, cost is low, esy to use, safe and reliable, the life-span long, centrifugal effective automatic balance of liquid centrifuge.

The purpose of this utility model is achieved in that by motor, the centrifugal whirligig that is installed on the motor output shaft to be formed, centrifugal whirligig by placement treat the well-bucket of centrifuge tube, the piston that is arranged on the well-bucket bottom and piston chamber, the tube connector that connects each piston chamber forms, in each piston chamber, can place soft capsule with favorable elasticity, be connected by tube connector between the soft capsule, on soft capsule, also have two openings, on two openings, lid is installed.

The utlity model has can automatic trim, laborsaving, cost is low, esy to use, safe and reliable, advantage that the life-span is long.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the soft capsule structural representation of being with of the present utility model.

Fig. 3 is a soft capsule structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the utility model is made up of motor, the centrifugal whirligig that is installed on the motor output shaft 1, centrifugal whirligig by placement treat the well-bucket 3 of centrifuge tube 2, the piston 4 that is arranged on well-bucket 3 bottoms and piston chamber, the tube connector 6 that connects each piston chamber forms.The structure of Fig. 1 on non-horizontal centrifuge, using.

Shown in Fig. 2,3, can place the soft capsule (plastic bag) 5,8 with favorable elasticity in each piston chamber forms, be connected by tube connector 6 between the soft capsule (plastic bag) 5,8, on soft capsule 5,8, also have two openings 9,10, be used for adding liquid, this liquid can adopt high specific gravity liquid, can be water, saturated brine or mercury etc., the big more anti-unbalance ability of its proportion is strong more, on two openings lid is installed.The lid of installing on the opening can not the leakage body.This structure is applicable on the mushroom-shaped centrifuge (as the LD-2 type), connects flexible pipe and can be fixed on the axis of centrifuge, and above-mentioned soft capsule can not use yet.7 is to place the test tube cover that uses when treating centrifuge tube 2 in well-bucket among the figure.

As shown in Figure 1, for non-horizontal centrifuge (as 800 types), can above-mentioned soft capsule, directly the piston chamber in the well-bucket of same aspect is interconnected and get final product, be full of high specific gravity liquid in it.
