Natural rubber field latex has been concentrated by a laboratory scale
centrifuge machine to attain ISO requirements. The optimum conditions
for various parameters e.g., frequency of the power source, flow rate
of the latex into the machine,ring dam diameter of the separator, tot
al solid content of the field latex, concentration of the preservative
in the latex, have been established The characteristics of latex conc
entrate were compared to those as required by ISO 2004:1974.
