Detailed Description
The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.
Although the conventional common plankton culture device can ensure that gas passes through a gas sterile filter when entering a culture system, the problems that sterility cannot be ensured in the sampling process, the sampling is left in a sampling pipe after the sampling is finished, the next sampling is influenced and the like exist. These problems can add data errors to the development and study of plankton including algae and zooplankton, and affect experimental results.
As shown in fig. 1 to 4, the inflatable type plankton sterile culture device for convenient sampling of the present invention is composed of a main culture bottle 1, a three-way bottle cap 2, a tripod 3, a sampling tube 4, a three-way sampling valve 5, a three-way bridging tube 6, an exhaust pipe 7, an intake pipe 8, an exhaust gas sterile filter 9, a three-way intake valve 10, a gas one-way valve 11, an air supply gas sterile filter 12, and an air supply pipe 13.
The three-way sampling valve 5 of the device has A, B, C three channels, the three-way air inlet valve 10 has D, E, F three channels, and the silica gel hose is in bridge connection with C, D two channels.
In the device, a culture bottle 1 is inversely fixed on a tripod 3 and is matched with the air inlet position setting of an air inlet pipe 8, so that the culture system is more fully mixed in the aeration process. The gas is filtered of bacteria and other contaminants by the feed gas aseptic filter 12; then enters the device body through the gas one-way valve 11, and the gas one-way valve 11 can prevent liquid from entering the gas-feeding gas sterile filter 12 and the gas-feeding pipe 13 along the gas-feeding pipe.
During the daily culture process, the B, C channel of the three-way sampling valve 5 is opened, and the E, F channel of the three-way air inlet valve 10 is opened; the gas passes only through the inlet pipe 8.
During sampling, the A, B, C channel of the three-way sampling valve 5 is opened, and the sample is taken out from the channel A. The D, E, F passage of the three-way intake valve 10 is open; the gas is divided into 2 paths, and the 1 path enters the culture system through a channel F and an air inlet pipe 8, so that the samples are fully mixed, and the sampling precision is ensured; the other 1 path is discharged out of the system along with the sample through a channel D, a bridging pipe 6, a channel C and a channel A, so that the sample cannot remain in the sampling pipe, and external gas is isolated from entering the system.
After sampling, the B, C channel of the three-way sampling valve 5 is opened, the D, E channel of the three-way air inlet valve 9 is opened and the F channel is closed at the same time, and the D channel is closed after all residual samples in the sampling pipe return to the culture bottle, so that the daily culture process is started.
In order to realize the whole wet heat sterilization of the device main body. The culture bottle 1 in the device is made of high borosilicate material; the three-way bottle cap 2 is made of corrosion-resistant and high-temperature polytetrafluoroethylene material; the sampling tube 4, the air inlet pipe 8 and the exhaust pipe 7 are made of corrosion-resistant and high-temperature Teflon hard tubes.
