Non-toxic, non-drying and non-hardening, the sealant is formulated to withstand centrifugation. There is no need for plastic caps or heat sealing. The tray has 24 numbered places for easy patient identification.
100% plastic microhematocrit capillary tubes are not made with natural rubber latex and are completely unbreakable. They comply with FDA, NIOSH, CDC, and OSHA safety recommendations. Tips are color coded for easy recognition of the tube types.
