The original white polypropylene trays for filed work and general lab use. Polypropylene is resistant to most chemicals and solvents and can be
autoclaved.
The small trays are great for pond sampling and the larger ones for sorting leaf litter. We do not recommend the larger tray for
aquatic sampling as it is a little too flexible to be carried full of water (see our heavy duty trays instead).
