这段中文翻成英文怎么翻啊？

Question

取药材粉末约0.5g，精密称定，置100ml圆底烧瓶中，加入25m1甲醇:氯仿(1:4)溶剂，置水浴上加热回流1.5小时，滤过，蒸干，甲醇定容至5ml，摇匀，0.45μm微孔滤膜滤过，即得。
大家辛苦了，不过貌似都有点中式英语，最好简洁点，把意思翻出来就行了，不用逐字逐句翻的~

Answer 1

take medicine powder about 0.5g, through precious weigh out, put 100ml into the round-bottom flask, add 25ml methanol
chloroform solvent in the ratio of 1:4, put the solution above the hot wate bath for 1.5hrs, filter, evaporate, add methanol to fix volume at 5ml, shake evenly, through 0.45μm millipore filtration, and finally get the solution we want.

呕心沥血之作啊，纯手工的

Answer 2

Take about 0.5 g, powder, buy 100 ml precision says the three-necked flask, join 25m1 methanol (4) solvent, chloroform, the heat water 1.5 hours, filtration, zhenggan methanol capacity to 5ml, shake, 0.45 muon m microfiltration membrane filtration, accordingly.

Answer 3

Take about 0.5 g, powder, buy 100 ml precision says the three-necked flask, join 25m1 methanol (1：4) solvent, chloroform, the heat water 1.5 hours, filtration, zhenggan methanol capacity to 5ml, shake, 0.45 muon m microfiltration membrane filtration, accordingly.

Answer 4

Medicinal powder from about 0.5g, said precision set,100ml flask, by adding 25m1 of methanol: chloroform (1:4) solvent, to return home heating in a water bath at 1.5 hours, filter, dry, methanol volume to 5ml , shake, 0.45μm millipore filtration, that is too.

Answer 5

take the drug ingredient powder about 0.5g,weigh it precisely and then put it into round bottomed flask with a volume of 100ml,then add methanol and chloroform mixture(1:4) solvent into the flask and put it in the warm water.After heated 1.5 hours,filter the solution and evaporate to dryness.Then add methanol to make the volume of the solution precisely 5ml,shake it up.Use the microporous filtering film with pore size about 0.45μm to filter the solution,thus, the result comes out.
呵呵，写论文写不下去了帮你翻译一下，算是练练手艺哈哈。
PS：翻译软件永远比不了人工翻译啊，看看楼上的翻译我真是苦笑不得

Answer 6

Take 0.5g powder of the medicinal material and weigh it precisely. Then put it into a flask with a round bottom and join in 25m1 methanol: chloroform solvent (1:4). After heating the flask in a liquid bath and reflowing the liquid for one hour and half, filter the liquid, steam it dry, dissolve to 5ml by methanol, shake it up and filter it using a membrane with 0.45μm micro holes. Finally it can be got.
