JHS presently has 8 lyophilizers All set for production use, 7 at our Spokane facility and two at our Montreal facility, with programs for an extra lyophilizer accessible in 2025. Two added lyophilizers will be competent by 2026 as Element of our ongoing facility growth in Spokane and one more in Montreal.
