These original white polypropylene trays are for field 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(Heavy duty trays available).Both sizes are also available as packs of three.
Small: 340 x 250 x 50mm
Large: 420 x 310 x 90mm
