也许你认为应该是“你不用小心.”的意思,但是英语里有一个习惯,就是too +形容词会有一种其他的意思,就是再..（怎么样）也不过分的意思,所以在这里,这句话的意思则是你在做实验的时候,再小心也不为过.

“你得小心做实验” 英语可以是：
Be careful with your experiment.
++++++
you don't be too careful in doing experiments
做实验时，越当心越好。

很明显楼主的句子还是不符合语法，你最好把原句给找出来，
下面这个句子才是正确的句子，才符合中文的翻译，否则文不对题。
You can't be too careful when (you're)doing experiment. 你得小心做实验

做实验的时候一定要小心
