nu-chek品牌介绍
品牌简介
Nu Chek高纯度脂质是在我们自己的实验室中从最好的商业动植物油源中分离出来的。奇数化合物的脂肪酸链通常通过扩链合成。饱和链和不饱和系列（多不饱和脂肪除外）总是通过在100理论板高真空分馏塔上的最终蒸馏来纯化。这样做是为了去除颜色和其他无关的微量杂质。只有那些即使GLC和TLC过载过大也无法检测到杂质的部分才可用于产品销售。
高纯度化合物（甚至饱和系列）的分离始终在惰性气体（即N2）的气氛下进行保护。除高熔点饱和化合物外，最终产品始终用氮气冲洗，在真空下密封在Pyrex玻璃安瓿中，并在-30°C或更低的低温条件下储存，直至准备装运。
Nu-Chek high purity lipids are isolated in our own laboratory from the best commercial animal or vegetable oil source available. Fatty acid chains of odd numbered compounds are generally synthesized by chain extension. Saturated chains and the unsaturated series (other than polyunsaturated fats) are always purified by a final distillation on a hundred theoretical plate high vacuum fraction column. This is done to remove color along with other extraneous trace impurities. Only those fractions on which impurities are unable to be detected even with large overloads both by GLC and TLC are made available for product sale.
The Isolation of high purity compounds (even the saturated series) are always protected under an atmosphere of inert gas (i.e. N2). The final product, with the exception of high melting saturated compounds, is always flushed with nitrogen, sealed in Pyrex glass ampules under vacuum, and stored under cold conditions of -30°C or lower until ready for shipment.
