为珍贵样品提供更安全保护！BRAND新型0.5 ml, 1.5ml, 2.0 ml 离心管上额外的盖扣，可确保有效的密封并避免意外开启。121 °C 高压湿热灭菌，2 bar，参照DIN EN 285标准 , 最高转速RCF 30000 g , 不含RNase，DNase，DNA 以及内毒素, 洁净车间生产，符合 ISO 14 644-1，8级 , 原材料选用高品质的医用级聚丙烯PPe , 在0.1，0.5，1.0，以及1.5ml处有分刻度, 管盖及管身上含磨砂标记区域. 产品细节: 盖扣: 新型BRAND离心管上额外的 盖扣，能够保护盖子免受意外 开启。加宽的盖缘: 加宽的盖缘方便人手操作。在样品于沸水中的变性过程, 以及在一般和加热条件下, 离心管需承受很高的压力.
带旋盖的微量储存管是诸如血清、血液样品储存、沸水浴、离心等操作的理想之选。 微量储存管具多种不同规格、 设计样式及质量等级可选。微 量储存管为PP材质，旋盖由 PE或PP材质制成，二者之间 精确匹配，确保极佳的密封效 果。带密封环: 带密封环的微量储存管格外适合于敏感样品的储存。密封环可有效减少硅胶密封环的污染风险。此类储存管不可高温高压湿热灭菌。带硅胶密封环: 硅胶密封环的密封效果极佳。此类储存管适合样品的液氮储存。此类储存管可 121 °C (2 bar)高温灭菌，参照DIN EN 285标准。带“显启盖”与硅胶密封环: “显启盖”能确保用户样品未受污染。一个明显的环扣作为抵抗开启的指示，当盖子第一次打开时，这个环扣将会崩断。这类储存管具有硅胶密封环，适合样品的液氮储存。具有“显启盖”的微量储存管可 121 °C（2 bar）高温灭菌，参照DIN EN 285标准。
The Sterility Assurance Level (SAL) describes the probability of a product being non-sterile after it went through the sterilization process. BRAND designs the sterilization processes of its products for an extremely low SAL of 10-6 . "One in a million" devices could be non-sterile after the sterilization process.
Only with some restriction. The mechanical strength of the material will deteriorate when exposed to γ-radiation. PP will become brittle resulting in a diminished permissable RCF. You can order sterilized micro tubes from BRAND ( Cat. No. 780400 and 780750-54 or 780755-59 ).
BRAND offers amber-colored reaction tubes (1.5 ml, Cat. No 780525) which are particularly suitable for the storage of light-sensitive reagents.
We do not sterilize the micro tubes with ethylene oxide. Should you like to test whether it works for your application, please ask for free samples. Please note that: 1.) during sterilization with ethylene oxide the tubes have to be out of the plastic package. 2.) after sterilization some ethylene oxide will remain in the material. You can order sterilized micro tubes from BRAND (Cat. No. 780400 and 780750-54 or 780755-59).
Micro tubes with screw caps with silicone seals (Cat. No. 780710-14, non-sterile, and 780750-54, sterile) can be used for storage in the gaseous phase of liquid nitrogen (-196 °C). Never submerge the tubes into the liquid phase, since intruded gas could cause the tubes to explode when heated up again.
All sterile BRAND products have a certain indicated shelf-life.
BRAND microcentrifuge tubes are manufactured out of pure granular polypropylene. They are manufactured and packaged under clean room conditions.
