Sample trays and holders are made from chemical and heat resistant materials to provide easy and safe handling of samples. This modular approach reduces the weight of the sample racks and requires less space for long term storage. The tray holder height is adjusted so that vials remain suspended to keep them free from any contamination. Sample trays may be placed directly over digestion blocks. Teflon coated trays should be used while working beyond 120C. All trays are available for each QBlock configuration.
