First, main technical parameters

Effective volume: 16.3L

Caliber: 80mm

Outer diameter: 455mm

Height: 441mm

Empty weight: 9.2Kg

Static liquid nitrogen retention period: is more than or equal to 54 d.

Second, use method

1. Filling liquid nitrogen: when liquid nitrogen is filled for the first time and refilled after long-term use, because the inner container is at normal temperature, the filling is not too fast, a small amount of liquid needs to be injected firstly, the inner container is cooled gradually, and the filling speed is increased after the liquid nitrogen boils slowly, otherwise the liquid nitrogen can boil and splash outwards, thereby causing frostbite. The liquid nitrogen should not be filled too full, and the liquid level should not be high enough to contact the glass fiber reinforced plastic neck tube. Instead of flushing the neck with liquid nitrogen, the filling tip should be inserted into the bottom of the container and refilled with liquid nitrogen.

2. Picking and placing refrigerated articles: when taking and placing the sample, firstly, the cover plug is vertically and lightly taken off, then the lifting cylinder is vertically lifted and lightly moved to the middle of the container, the cover of the lifting cylinder is opened, and the sample is taken and placed. It is preferable to take and place the object in the neck tube of the container (if the lifting cylinder must be lifted out of the container and then the object is taken and placed, after the liquid nitrogen higher than the side hole of the lifting cylinder is discharged, the lifting cylinder is lifted out of the container, so that the liquid nitrogen is prevented from escaping from the side hole and hurting people). After the container is taken and placed, the cover is closed immediately to slightly reset the lifting cylinder and the cover plug, attention is paid to shortening the opening time of the bottle mouth as much as possible, and the lifting cylinder cannot be completely taken out at the same time so as to prevent the container from absorbing moisture in the air, increase the evaporation loss of liquid nitrogen and influence on the storage effect of frozen articles. When the barrel is passed through the neck, care is taken not to hit the neck, so as not to damage the container.

3. Liquid level height inspection: the lowest liquid level energy of the liquid nitrogen is lower than the highest surface of the refrigerated object so as to ensure that the refrigerated object is submerged by the liquid nitrogen. When the liquid nitrogen is evaporated to the extent that the refrigerated object is exposed to the liquid surface, the liquid nitrogen is supplemented in time. The container can judge the liquid nitrogen height by eyes after the cover plug is opened according to the optimized overall dimension and caliber, and other measuring tools are not needed.

4. And (3) evaporation loss determination:

the weight method and the flow method are used for measurement.

The flow method is measured by a gas flowmeter, and the operation method is described in the specification of the flowmeter.

The weighing method uses a platform scale for weighing, and uses the platform scale which passes the test in 50K so as to avoid inaccurate weighing.

And (3) after the container which is not precooled is filled with liquid nitrogen, placing for 24-48 hours, fully cooling the container, and then measuring the sun evaporation loss. Weighing the container firstly, weighing once again after 24 hours, wherein the difference of the two weights is the daily steaming loss of the container, and continuously measuring for three days. The average daily steaming loss of the container is calculated firstly, and then the daily steaming loss rate and the liquid nitrogen retention period are calculated.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
