The single string datum you've given looks like it should match the regex pattern:

(\d*)x\s(\d*\.\d*)\smL\s(.*)\.\s(\d*)x\s(\d*\.\d*)\smL\s(.*)\.

You can use it with Regex Evaluation step:

Use split function and regex \. | mL |x

var text = '1x 3.5 mL SST. 1x 4.0 mL gray cap cryovial'
arr = text.split(/\. | mL |x /g)

var tb = document.getElementById("table")
//creat row
var tr = document.createElement("tr")

for (s of arr) {
  // create cell
  var td = document.createElement("td")
  var txt = document.createTextNode(s);
  td.appendChild(txt)
  tr.appendChild(td)
}

tb.appendChild(tr);

<table id='table' border="1">
  <tr>
    <th>Par_Count</th>
    <th>Par_Qty</th> 
    <th>Par_Tube</th>
    <th>Child_Count</th>
    <th>Child_Qty</th>
    <th>Child_Tube</th>
  </tr>
