Magnifying Surgical Loupes
We do a better job when we can clearly see the details of the task at hand. Unfortunately, when working with small objects we tend to bend over in unnatural positions for extended periods of time. This can result in eye strain and back pain that can have long-term, detrimental consequences to our overall health and well-being. Using surgical loupes quickly improves vision and corrects poor posture.
How to Choose the Right Product? Magnification in 2X, 3.5X, and 4 X Strengths - A 3.5x and 4X magnification surgical loupe reveals incredible detail but comes with a small field of view (30MM.) Your working distance has to be maintained more accurately, too. Choose a 4X loupe if you want to focus on a narrow work area and need to see the details that a higher magnification affords. A lower 2.5X magnification results in wider field of view (50MM) and lets you monitor a broader work area. Because of their greater depth of field, 2.5X surgical loupes allow more freedom of movement as they are less sensitive to changes in your working distance.
Working Distance - Working distance is the approximate distance between your eyes and the object you work on. To choose a pair of surgical loupes with the right working distance, imitate the circumstances of a surgical procedure and try measuring your working distance. Keep your back straight and be in a comfortable working position. People below 57 height usually need loupes with 340 mm working distance while taller persons need ones with 420 mm working distance in a sitting position.
Illumination - Vision can never be perfect without proper lighting. In case your work area is hard to light up, use our super bright LED light that attaches to our surgical loupes. There are two intensity levels and the power is adjustable at each level. You will find it hard to look into the illuminated area at maximum power setting. The battery can run for 7 hours continuously at the lower level or for 4 hours at the high level. The light weighs only 11 g and it illuminates a spot with a 70 mm diameter from 400 mm with 6000 K (pure white) color.

westblot蛋白免疫印迹实验跑小分子蛋白（15kd）条带一直是波浪状，有人说是胶的问题，可同时跑了36kd蛋白，条带是直的，有人说是要恒流跑，电压不要太大，我的转膜条件是50v，50min，请教各位大神指点，万分感谢！！！
有机的是有机化合物的简称,它指的是含碳化合物.
但是,有四大类常见物质一般不作为有机物处理：
1、碳的氧化物,如CO和CO2.
2、碳酸及其盐,如CaCO3.
3、金属碳化物,如CaC2.
4、拟卤素及其化合物,如(CN)2与KSCN.
水的化学式为H2O,它不含有碳元素,故不是有机物.
但若所描述的水不是化学意义的水,而是自然界存在的天然水,那么,水中会溶有一定量的有机物.
求助各位大神，现在想购买小分子数据库，求大神推荐。
我知道的免费的数据库有zinc
求推荐哪家公司或者研究所的小分子数据库可以购买，十分感谢！！！！！！
求助各位前辈，我最近在合成的化合物水溶性很好，非常好，以至于可以随便溶解在水里，它的六氟磷酸盐也可以随意溶解在水里（大于50uM），细胞成像实验显示它根本进不去细胞，求问有没有啥方法包裹一下让它进去？我搜了一下文献，感觉多数是把脂溶性特别好的东西包裹一下弄进去的，也许是搜索姿势不对没找到我需要的答案，**点拨啊！！！
求助大家，小分子药物最新专利申请情况跟踪，之前听别人说可以在一个网站可以导出这个信息。
不知哪位大侠知道，告知一下，不胜感激！
