Thor 低温有限公司采用真空多层超级绝热技术已制成一种能贮存样品达31天,保温在-196℃左右的液氮冷却致冷器。此致冷器是为在试验室条件下冷冻和贮存样品而设计的,所有部件都是用不锈钢制成的,而且是在惰性气体保护下用电弧焊焊制而成,它装有小脚轮,可四处移动。用直接浸入液氮的方法可把样品迅速冷冻,或逐渐浸入汽氮(-120℃)可使样品慢慢冷冻。根据需要,该设计无论是用液氮还是用汽氮冷却,都能使样品长期贮存。
Thor Cryogenic Co., Ltd. has adopted vacuum multi-layer super-adiabatic technology to make a liquid nitrogen cooled refrigerator capable of storing samples for up to 31 days and holding at about -196 ° C. Designed to freeze and store samples under laboratory conditions, all components are made of stainless steel and are arc-welded under inert gas protection. They are fitted with casters Move around. Samples can be rapidly frozen by direct immersion in liquid nitrogen or gradually frozen in vapor-nitrogen (-120 ° C). Depending on the need, the design, whether using liquid nitrogen or nitrogen gas cooling, can make long-term storage of samples.
