Allergy Skin Testing Tray

Greer Labs has introduced the Skin-testor Omni™ allergy tray to test patients for allergen sensitivity. The tray can hold four Omni™ devices and up to 40 aller-genic extracts. It fits securely over each well to protect the extract from spilling and to prevent contamination. Made of a sturdy synthetic clear plastic, the tray is 4 inches wide by 11 inches long. It can be stacked on top of another tray to save storage space. buy antibiotics canada
