b**********s 发帖数: 410 | 1 感谢大家的input,非常有帮助。
能否再请教一下peristaltic pump, flow pump, syringe pump 的区别?
我们的实验只需要让液体从一侧流入,另一侧流出即可,所以实验探索阶段用注射器注
入确实也是一个可行办法。
我们准备测量液体注入之前和流出之后的电化学性质,是不是只能注入之前测量一次,
流出之后收集再测量一次?有没有更好的办法?
谢谢! |

There's no cure for the common cold. But what about cold remedies that claim

Cold remedies are almost as common as the common cold, and many are nearly

意见。
实验室里有一个5.5立方米的气袋,我的实验是:每次用syringe 吸取一定量的a-
pinene 或者是
limonene,大概是8uL或者是16uL,然后让干净的流动空气带着挥发的有机物进入气袋
。每次我大概让空
气充气袋40分钟-1个小时左右。(当然,提前先抽空一部分气袋,大概抽空20%左右)
。 这样气袋里面就充
满了带有样品的气体。当然这个时候,气袋是密封住的。所有的开口都关上。
然后我用tube连上泵,泵就以5L/min的速度从气袋里面抽空气流过tube。我就把SPME
fiber放在tube的
中间,然后让流过的样品空气,这样SPME就把样品吸附上去。
我的采样时间是2分钟。然后立刻用GCMS去分析样品。
采样条件

s****e 发帖数: 2934 | 8 俺不是很信,再说从80%提高到99。9%有什么很大意义吗。我用alumina也有这种情况
,慢倒不慢,我当时猜是因为alumina催化乐我的polymer发生了反应,也有文献证据,
我就用syringe driven filter过滤一下拉倒。以后就不用alumina了。 |

m********h 发帖数: 405 | 9 yes, my polymer is completely soluble in THF. that is the solvent I used
for GPC. the strange thing is I made the 1mg/ml solution in THF. it is
completely transparent and soluble. also there is no viscosity at all.
but it is so difficult to pass the 0.45 micron PTFE whatman syringe filter.
why is that?
so I wonder because my polymer has high molecular weight, the random coil
is so large than 0.45 micron ? is it possible? I don't know polymer
physics well. |

g***e 发帖数: 584 | 10 如果二者反应速率差太大了,你只能多加点反应速率慢的看看能不能弥补,或者你混个
比例,然后用个syringe pump慢慢的加单体,但是这个也很难控制,你还得慢慢算。你
可以隔段时间取点样然后去测nmr,看看某种单体的含量随着反应时间的变化,然后把
那么多点做个图,是不是block copolymer应该看的很清楚,至于怎么个random程度,
就看你怎么加单体了。 |

回头一想,我应该问医生哪里inject呀,methimazole我知道是耳朵,insulin人是打

t****5 发帖数: 40 | 29 Westmore MM,
Thanks for your advice.
I counted syringes. I have 34 in total.
Lupron & Follistim是打在肚皮上 or upper leg. Someone said it's easy for body to absord the medicine if you inject 在肚皮上.
My nurse only taught me how to inject Lupron & Follistim. I'm not confident
if I'll do it right. There's injection instruction on line.
By the way, be sure to refrigerate Lupron after opening. Follistim needs to be refrigerated, too.
Keep close contact. |

我也觉得很是奇怪,你trigger当天U/S不是看到左右卵巢有不少卵泡的吗? 你的HCG是
pre-filled syringe 还是需要自己mix powder和水的那种? 昨天早上你的诊所有给你
做ER前的final B/W和U/S吗? 一定要质问你的医生,到底是卵泡提前自己释放了还是HCG
剂量不对!
不要放弃,希望明天右边卵巢会有好消息.

万分感谢姐妹们的买药经验帖!发现确实ivfmeds.com的药很便宜,很心动。看了医生
给的prescription list, 发现上面还有很多accessories比如针头啊,Normject
syringes HSW (For injecting Menopur)什么的,这些是要单独买还是订药的时候会附
送? 还有follistim pen,我看买的时候写的是cartridge for pen, 那么PEN要单独
买么?还是会送?针头要用什么大小的啊? 如果在ivfmeds.com订药的话,有什么TIP
或者注意事项?
用过的姐妹们请说一说吧?多谢多谢! |

k**a 发帖数: 1124 | 33 yes, needles/syringes are all free. pen is the actual medication! the meds
are in the pen. hehe. some mms like the needle to be as thin as possible,

manageable.

M********8 发帖数: 3837 | 34 Follistim/Gonal-f pen都会有多余的药,比如300IU的,他里面就会有420IU左右(包
装上会说明),方便你打针出来的时候剂量足。但是那剩下来的120IU你就没法打出来
,怎么办呢?
自己去找网上30 gauge syringes(通常都是cc, ml, 没有IU单位的), 然后纪录每个
pen最后剩下来的剂量。然后呢,用自己买回来的针筒把剩余的剂量给抽出来,集少成
多,起码可以挤出一天的用量来了。我打11天的时候,有差不多3天多的剂量都是这么
挤剩余挤出来的。
副作用是什么?剂量未必精确,因为你是靠记录剩余剂量来估摸,cc换算iu也没有公式
,所以挤出来的剂量是个大概。还有呢,针筒头抽了两三只笔后,就会钝掉,你再拿这
个扎自己,就比较疼一点。不过能省好几百,疼点也就无所谓了。 |
