in use (84-100-235)
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.

Sample Cart (84-100-237)

Sample Storage Cart
Many laboratory practices require digested samples be preserved for stipulated periods of time. This Sample Cart is made from chemical resistant material and will accommodate 840, 50 mL samples. The shelves that hold the sample tray holders are inclined to prevent tray holders from accidently sliding off the cart. For easy access, the cart has 4 compartments. Each compartment has a place to hold empty trays at the bottom. Space is provided on the top of the cart to place the sample records.  Sample cart is compact (50” high, 28” wide) and is mounted on wheels for easy maneuverability.
