Play Design Toys: Making science simple for 20 years


Play Design Toys licenses Radosevich's food grade edible simulated environmental samples for training.  Food grade means no personal protective equipment is needed  (respirators, gloves), cleanup is easy with wet paper towels, and disposal is household compatible.  Suitable for classroom use. 



Simulated soil samples accurately simulate soils from alluvial silt to sandy loam.  Primary sieve to < 2mm with inclusions.  Separable to 5% with sieving.  Clumping agent active when damp - requiring attention to drying technique, and the samples provide an interesting x-ray fluorescent spectra.  Gluten-free, lactose-free, no soy, no peanuts, and no tree nuts.  Contains < 0.05 mg respirable silica bound in matrix.   Gram samples in 4 ounce Whirlpak bags with barcoded labels.  Sample grid tagged variable content available on request.




Separable liquid samples contain a mixture of naturally occuring food grade aromatics, trace elements, and coloring agents in solution and colloidal suspension.  Suitable for x-ray fluorescence spectral analysis subsequent to preparation chromatography.  Ratio coded labeling, pure component samples, and >50 keV spectra included.  Water and ethanol base, Denatonium benzoate available on request.  Gluten-free, lactose-free, no soy, no peanuts, and no tree nuts.  40 ml samples in 50 mil cone bottom standing ring base centrifuge tubes with barcoded labels.
