Abstract
The invention provides a coating stick for bacterial culture, and belongs to the technical field of coating sticks, wherein the coating stick is used for solving the problem that the temperature of a coating section in a traditional coating stick is difficult to control. The coating stick comprises a cap head, a metal wire, a handle section and a coating section. The handle section and the coating section are connected into an L-shaped whole. The top end of the cap head and the top end of the handle section are connected in a spiral mode. The metal wire is fixedly connected into the cap head. The other end of the metal wire extends into the handle section and reaches the joint of the handle section and the coating section. The coating stick for bacterial culture is simple in structure and convenient to operate, the temperature during coating is controlled only by taking out the metal wire and judging the temperature of the coating section according to the temperature of the metal wire, and the coating stick can be widely used for bacterial coating in biochemical activities.
Description
Technical field
The invention belongs to spreading rod technical field, particularly relate to a kind of spreading rod for microbial culture.
Background technology
Spreading rod is a kind of conventional biological experiment instrument, but just can reuse after mostly needing to carry out high temperature sintering when using spreading rod, to eliminate the residual bacterium liquid of front single job.In experimentation, experimenter has often prepared many spreading rods and has alternately cooled use, but still cannot judge and ensure whether spreading rod to be used has been cooled to room temperature, if temperature drift, easily scald the strain bio of dead coating, if cooling time is oversize, waste a large amount of waiting time.
Summary of the invention
For solving the problem, the invention provides a kind of spreading rod for microbial culture, adopting following technical scheme:
For a spreading rod for microbial culture, it is characterized in that, described spreading rod comprises cap head 3, wire 4, handle section 2 and coating section 1; Described handle section 2 and coating section 1 are for connecting into the entirety of " L " type; Described cap head 3 is connected by spiral with the top of handle section 2; The inside of described cap head 3 is fixedly connected with wire 4, and the other end of described wire 4 extends to the inside of handle section 2, and arrives the junction of handle section 2 and coating section 1.
Preferably, the material of described handle section 2 and coating section 1 is glass.
Preferably, the outer wall of described cap head 3 processes anti-skidding embossing.
Beneficial effect of the present invention is as follows:
1. the spreading rod for microbial culture provided by the invention, structure is simple, and handle section and coating section, for connecting into the entirety of " L " type, are beneficial to the coating of circular culture dish periphery bacterium, make culture sample can coat the surface of culture dish equably, but not pile up at the periphery of culture dish.
2. the spreading rod for microbial culture provided by the invention, the inside of cap head is fixedly connected with wire, the other end wiry extends to the inside of handle section, and arrive handle section and the junction being coated with section, and cap head and handle section are spirals to be connected, the benefit that this kind is arranged is as follows: before bacterium coating, when High Temperature Sterilization is carried out to coating section, transfer heat to the wire in handle section simultaneously, when whether the temperature to detect coating section is cooled to the temperature of needs, only need rotation that cap head is separated with handle section, take out wire, tip wiry is known by feel, the temperature being coated with section can be estimated, thus determine whether that applicable bacterium is coated with.
3. the spreading rod for microbial culture provided by the invention, structure is simple, easy to operate, and the bacterium coating that can be widely used in biochemical activity uses.
Accompanying drawing explanation
Fig. 1 represents structural representation of the present invention; Wherein, 1 represents coating section; 2 represent handle section; 3 represent cap head; 4 represent wire.
Embodiment
Below in conjunction with embodiment, set forth the present invention further, but be not used in and limit the scope of the invention.
embodiment 1
For a spreading rod for microbial culture, as shown in Figure 1, this spreading rod comprises cap head 3, wire 4, handle section 2 and coating section 1; Described handle section 2 and coating section 1 are for connecting into the entirety of " L " type; Described cap head 3 is connected by spiral with the top of handle section 2; The inside of described cap head 3 is fixedly connected with wire 4, and the other end of described wire 4 extends to the inside of handle section 2, and arrives the junction of handle section 2 and coating section 1.
Preferably, the material of described handle section 2 and coating section 1 is glass.
Preferably, the outer wall of described cap head 3 processes anti-skidding embossing.
The using method of this spreading rod is as follows:
Before bacterium coating, when High Temperature Sterilization is carried out to coating section, transfer heat to the wire in handle section simultaneously, when whether the temperature to detect coating section is cooled to the temperature of needs, only need rotation that cap head is separated with handle section, take out wire, know tip wiry by feel, the temperature being coated with section can be estimated, thus determine whether that applicable bacterium is coated with.
Claims (3)
