Fig 3. Comparison of cold packs and their cost efficiency.

Fig 3

(A) Temperature curve in rotomolded cooler #13 with 0.45 kg of cold pack E with and without secondary containers. Lines represent the average of three experiments. (B) Cold time for various cold packs and the frozen water bottles in rotomolded cooler #13. Point represents the mean of three independent runs. Experiments were run in triplicate. Statistical significance was determined by a one way ANOVA with Tukey’s multiple comparison test. *P-value < 0.05, **P-value < 0.01. (C) Time in hours 1 kg of cold packs remained below freezing when not in a secondary container. Each point represents an independent run and the red bar represents the average. Statistical significance was determined by a one way ANOVA with Tukey’s multiple comparison test. *P-value < 0.05. (D) Cost effectiveness of cold packs as determined by cold time in Fig 3A. Red bar represents the mean, n = 3.
