<span style="text-align: justify; font-family: arial, sans-serif; font-size: small;">Take Reagent COD TK 2 in a plastic tube up to the neck (3.5 ml) and transfer it to the above sample solution tube . Close the cap tightly . Mix Well by swirling (Use of safety goggles and hand gloves is recommended )</span><br style="text-align: justify; font-family: arial, sans-serif; font-size: small;" />
<span style="text-align: justify; font-family: arial, sans-serif; font-size: small;">Take approximately 30-40 ml of paraffin wax in 100 ml glass beaker hit it on a hot plate till temperature up to 150 degree centigrade. (Use Thermometer).</span></p>

(If strong bubbling observed in to the screw cap glass tube solution then disconnecting heating as it may lead to explosion of glass tube sample may contain volatile constituent and hence this method is not suitable for the above sample discontinue & discard the glass tube solution after cooling. And follow the para 2.</span><br style="text-align: justify; font-family: arial, sans-serif; font-size: small;" />
