DNA extraction was carried out using the 5% Chelex method. using Univariate and one-way ANOVA. DNA quality was observed based on the comparison results of Å260 and Å280 on the SimpliNano spectrophotometer. The results showed that the concentration of DNA in glass, plastic and ceramics was not significantly different in each treatment. There was no interaction between the type of glass and hand touch, the average DNA concentration. Extracted DNA showed poor quality
