MetalFree® Tubes Prevent Assay Interference in Sensitive Applications

从传统塑料消耗品中提取金属是测试实验室一直关注的问题，被认为是许多实验异常的原因。即使是玻璃器皿，在盐酸等酸的存在下，也会释放出金属，污染样本，扭曲结果。Addressing this, the new MetalFree® centrifuge tubes now available in the UK fromAlpha Laboratoriesare intended for the storage, high-speed centrifugation and analysis of samples requiring ultra-low trace metal contents.

MetalFree管和帽是专门制造的，以确保常见的微量金属低于ICP-MS检测水平的十亿分之一。市场上大多数其他的离心机管只认证低于百万分之一。The tubes are analysed for 21 different metals including Calcium, Magnesium, Zinc, Vanadium, Cobalt, Lithium, Cadmium, Iron, Manganese, Copper, Sodium, Chromium, Lead, Mercury, Aluminium, Silicon, Nickel, Phosphorus, Potassium, Selenium and Arsenic

这些无金属管非常适合受金属污染物影响的应用，并且在法医、采矿和环境科学(包括水分析、土壤测试、地质学、生态毒理学和食品安全)中日益增长的必要性。离心管在临床环境和科学发现中也是理想的，被推荐用于ICP-MS分析，酶辅助提取/分离和x射线晶体学，甚至微量的金属存在会干扰结果。

Alongside the assurance that metal leaching will not affect experimental accuracy, these tubes are manufactured through environmentally responsible methods. Waste free electronic moulding machinery uses 40% less energy, whilst printed graduations are UV-cured, a process mitigating the release of VOC pollutants.
