众所周知,在酿造和酿酒行业,用于投入发酵的酵母的数量直接影响最终产品的风味、香气和质量。虽然酵母可以通过重量或体积来投入,但这种方法是不精确的,而且变异较大。使用亚甲蓝的ASBC法比较准确,但耗时长,主观差异大。使用LUNA-II YF™计数仪能够在短短15秒内获得准确和可重复的酵母细胞计数。 这款多功能小巧的计数仪可方便地放置在细胞培养室或您的工作台上,以无缝融入您的工作流程。

准确的酵母细胞计数
LUNA-II YF™ 拥有无可比拟的精度、一致性细胞计数及细胞活性数据。
15秒获得结果
LUNA-II YF™采用双荧光光学,自动聚焦液体透镜、先进的软件,只需15秒即可生成数据。
优化的酵母分析
与流式细胞仪不同,LUNA-II YF™具有先进的去团化功能,即使是最严重的聚团细胞也能计数。
经多个菌株验证
在LUNA-II YF™上独立测试了30多个酿造酵母产品。请通过访问细胞数据库以获得部分列表。
改变一切的软件。
最低的成本,最大的方便。
我们的LUNA™系列自动细胞计数仪与LUNA™可重复使用计数板配合使用,非常适合预算有限的实验室。LUNA™可重复使用计数板,像手工计数法一样节约耗材成本,又避免了手工计数的耗时、及受主观影响导致用户之间的计数差异的弊端。我们的一次性计数板可以提供舒适的计数体验。这些精密的细胞计数板无需进行清洗,使用方便并确保细胞计数的准确度。

Great product. I am an equipment manager. I am very pleased with this product to check and count enamel in beer. Fast, accurate and complete parameters are the most basic factors. It is very easy to use. After sales care service is very good. Product worth the money.
