Description

Technical Field

[0001] The utility model relates to the technical field of test instrument equipment, in particular to a temperature-controlled plate pouring device. Background Art

[0002] In laboratory-related activities, antibiotics are often added to LB solid medium to screen specific resistant colonies. "Pouring a plate" means pouring the liquid agar medium sterilized at high temperature into a culture dish and cooling it to solidify into a solid medium. In the traditional plate pouring process, since antibiotics will lose their activity at high temperatures and the LB medium will solidify at lower temperatures, it is necessary to pour the plate within a suitable temperature range. Experimenters often rely on hand touch to empirically judge the temperature. This process may not only result in misjudgment, but also make the experimenter's hands feel extremely uncomfortable at higher temperatures. In addition, the amount of medium poured and the shaking all need to be completed based on experience, and there are often situations where the thickness of the solid medium is uneven and the plane is inclined.

[0003] As disclosed in the patent application No. CN213943169U, "A Plate Pouring Device for Laboratory Use", it includes an inner container located in a cavity. A small steam sterilization device is provided inside the main body. A steam outlet connected to the small steam sterilization device through a steam pipe is provided in the cavity. The lower end of the inner container is connected to an outlet pipe, and a valve plate for blocking the outlet pipe is provided on the side of the main body.

[0004] Although the prior art avoids hand contact with the medium and reduces the labor intensity and danger of personnel, during the LB plate pouring operation, it is impossible to judge when to add antibiotics, and there may also be a situation where the medium solidifies after cooling and blocks the outlet, making it difficult to clean. At the same time, its automatic pouring can only control the switch, and the water pressure plus the steam pressure result in inconsistent water flow rates, easily causing overflow or being too thin. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions of the present utility model will be further specifically described below through examples and in conjunction with the drawings.

[0024] Example: As Figures 1-4As shown in the figure, a temperature-controlled pour plate device includes a box frame 1. Inside the box frame 1, there is an oscillator 4. At the upper end of the oscillator 4, there is an oscillation tray 401. At the front end of the oscillator 4, there is an oscillator display screen 402. There are 4 speed adjustment buttons 403 on the side of the oscillator display screen 402. There are also a power-on button and a power-off button beside the speed adjustment buttons 403. Above the box frame 1, there is a sterilization bottle 2 extending out of the upper end of the box frame 1. Between the box frame 1 and the sterilization bottle 2, there is a support frame opening I 101 inserted into the sterilization bottle 2. At the upper end of the sterilization bottle 2, there is a bottle mouth 201. At the lower end of the sterilization bottle 2, there is a liquid outlet pipe 203 inserted into a constant volume tube 5. On the liquid outlet pipe 203, there is a two-way cock I 204. On both sides of the upper part of the sterilization bottle 2, there are handles 202. At the lower end of the sterilization bottle 2, there are 3 support legs 205 distributed in a ring. Around the sterilization bottle 2, there is a heating coil 6 nested with the sterilization bottle 2. The heating coil 6 includes an insulating shell 602, and the insulating shell 602 is fastened by a locking part 601. The locking part 601 consists of a pair of locking blocks and a screw pin. Between the insulating shell 602 and the sterilization bottle 2, there is a ceramic heating wall 604. On the insulating shell 602, there is a heating coil plug 603 in communication with a thermometer 3. At the lower end of the sterilization bottle 2, there is a constant volume tube 5 extending above the oscillator 4. The constant volume tube 5 includes a constant volume tube body 502. Between the upper end of the constant volume tube body 502 and the liquid outlet pipe 203, there is a rubber sleeve 501. At the lower part of the constant volume tube body 502, there is a two-way cock II 503. On the side of the front end of the box frame 1, there is a thermometer 3 in communication with the heating coil 6. Beside the support frame opening I 101, there is a support frame opening II 102. On the support frame opening II 102, there is a temperature measuring probe 305 in electrical communication with the thermometer 3. At the upper part of the thermometer 3, there is a thermometer display screen 301. At the lower end of the thermometer 3, there is a thermometer plug 304. At the lower part of the thermometer 3, there is a heating coil socket 303 in electrical communication with the heating coil plug 603. Between the heating coil socket 303 and the thermometer display screen 301, there is a temperature setting button 302.

[0025] Working principle: When the two-way cock I 204 is closed, the sterilization bottle 2 is poured with agar medium through the bottle mouth 201 for high-pressure steam sterilization. The support legs 205 support the sterilization bottle 2 during sterilization. After sterilization, the sterilization bottle 2 is supported on the opening I 101 of the support frame through the handle 202, and the shape of the opening I 101 of the support frame allows the bottle body and the support legs 205 of the sterilization bottle 2 to pass through. The temperature measurement probe 305 of the thermometer 3 enters the bottle mouth 201 through the opening II 102 of the support frame to measure the temperature. The radius of the heating coil 6 is slightly smaller than the radius of the bottle body. After opening the locking member 601, it is sleeved on the bottle body of the sterilization bottle 2, and the two locking blocks on both sides are tightened by relying on the locking member 601 through the threaded pin, thereby increasing the pressure on the sterilization bottle 2. The ceramic heating wall 604 is heated, and the insulating shell 602 is used to avoid high-temperature scalding when contacting. The heating coil plug 603 is connected to the thermometer 3 through the heating coil socket 303, and the thermometer 3 sets the upper and lower limits of the temperature range through the temperature setting button 302. The set temperature value and the measured temperature value are both displayed on the thermometer display screen 301. When the measured temperature is lower than the lower limit of the set value, the heating coil socket 303 is powered on to control the heating of the heating coil 6. When the measured temperature is higher than the upper limit of the set value, the heating coil socket 303 is powered off to cool down. After reaching the appropriate temperature range, antibiotics are added from the bottle mouth 201 at the set temperature.

[0026] When pouring the flat plate, the constant volume tube 5 is connected to the end of the two-way cock I 204 through the rubber sleeve 501 to realize the assembly and disassembly of the constant volume tube 5. Open the two-way cock I 204, and the agar medium located in the set temperature value range and with antibiotics added is introduced into the constant volume tube 5 through the liquid outlet pipe 203 and the orifice of the two-way cock I 204. The constant volume tube body 502 is marked with scales. When the target scale is reached, close the two-way cock I 204 and open the two-way cock II 503 to drip a certain volume of agar culture on the culture dish placed on the oscillation tray 401. The oscillation speed is displayed on the oscillation instrument display screen 402. The operator adjusts the speed control button 403 to adjust the oscillation instrument 4 to a certain speed so that the culture medium dropped on the culture dish is evenly distributed around the culture dish.

[0027] In summary, the temperature-controlled flat plate pouring device has the characteristics of simple structure, convenient adjustment operation and good operation stability. Through the external temperature control device, the temperature of the culture medium is maintained within the set range, avoiding the problems of antibiotic inactivation and medium solidification midway, and improving the effectiveness and utilization rate of the resistant medium. Through the sterilization bottle piston and the constant volume device, the control of the flow rate and the volume of the culture medium is completed, improving the accuracy of the work. By replacing manual shaking with an oscillator, the contact between the experimenter and the high-temperature culture medium is avoided, reducing the work intensity and danger of the experimenter.
