Dynamic date time slicer

Hi, Dieu 

ryan_mayu's solution is perfect. 

And I would like to share some additional solutions below.

According to your description, you want to create a slicer of lot number so that when you select lot number, you can see information in that time periods? 

If I understand you correctly, then you can refer to my solution.  

I have extended the dataset based on some of the data you provided: 

Then you can New table： 
 

CombinedTable = 
VAR LotTable = 'Table1'
VAR InfoTable = 'Table2'
RETURN
    SELECTCOLUMNS (
        FILTER (
            CROSSJOIN ( LotTable, InfoTable ),
            Table2[Sample time] >= Table1[Intake Time Start]
                && Table2[Sample time] <= Table1[Intake Time End]
        ),
        "Lot number", Table1[Lot Number],
        "Intake Time Start", Table1[Intake Time Start],
        "Intake Time End", Table1[Intake Time End],
        "Sample time", Table2[Sample Time],
        "Information", Table2[Information]
    )

Finally add a Slicer and drag Lot Number into the field to filter it: 

Here is the result: 

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.
