Designed to apply firm pressure on the sample while mimimizing tissue damage, Radnoti Tissue Ring Clips allow easy clamping of small and large tissue samples. The ring coil is seperated and held open (using a small needle) and the sample is placed between coils. When the needle is removed the spring tension of the stainless steel spring wire maintains even and firm pressure on the sample. One ring is used at the top of the sample and another at the bottom. The rings are then connected to the lower support or up to the isometric force transducer via non stretch suture(*recommended suture size #0 non stretch.) or stainless steel wire (Radnoti part number 158815-6). Provided in packages of twelve.
