ASI Weigh Boats are made of antistatic polystyrene and will withstand temperatures to 90˚C, as well as exposure to diluted acids, alcohols, bases and aqueous solutions. Their flexibility and smooth interior surfaces with rounded corners allow for easy decanting of powdered samples. Their flat bottoms ensure stability and prevent tipping. Weigh Boats are available in the traditional square shape and come in black. Originally designed as weighing containers, they have proven ideal for dispensing and storage and as disposable mixing/quick freezing trays. 500/pk
