A light-curable epoxy suitable for solar cell and LED encapsulation. Sets at wavelengths of up to 350 nm and is safe for use with most organic materials.
Curing wavelength: up to 350 nm
Usage:
approx. 100 μl per standard sized substrate (10 ml ~ 100 standard substrates)
approx. 600 μl per scale up sized substrate (60 ml ~ 100 scale up substrates)
Datasheet
Ossila's E132 PV & LED Encapsulation Epoxy can be used as an adhesive for organic light-emitting diodes and organic photovoltaics without damaging the polymer or cathode. In conjunction with a glass coverslip, it can provide a robust barrier against ingress of oxygen and water, thus providing extended lifetimes for measurement and storage.
Curing can be achieved with UV or visible wavelengths as long as 350 nm, and at high intensities (100 mW/cm2) takes as little as 5 seconds. At lower intensities (such as those found in many lab-scale light boxes), curing time may be considerably longer (at up to 20 minutes).
Our encapsulation epoxy has been shown to encapsulate flexible substrates during an Innovate UK funded investigation.
PV & LED Encapsulation Process with Ossila Epoxy
For small substrates (up to 2 cm2), place a single drop of epoxy dispensed from the end of a pipette onto the surface of the substrate, and place a glass cover-slip over the top. The encapsulation epoxy will then spread under the weight of the cover-slip over the course of a few seconds.
Check for voids and air bubbles under the cover-slip and if necessary gently press down on the coverslip to remove. Ensure the active area and metal cathode are covered.
Place in a light-box and expose until hardened.
Please also note: If used in a glovebox, the encapsulation epoxy should be allowed to de-gas any absorbed oxygen/water for at least 24 hours prior to entering the glovebox.

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!!!
如题,之前没做过药代,老师给了一个600+Da的五肽,想测下药代动参数,看文献推荐上述两种方法,但是不知道选哪种更好,lcms前处理会不会影响小肽。
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!!!!!!
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.
