Production process

Our blood collection tubes are meticulously organized and stacked in standardized, clean trays within a dust-free workshop. Each product is securely placed to prevent contamination or damage during storage and subsequent distribution.

Each batch is clearly labeled with essential information, including lot numbers, production dates, and specifications, ensuring full traceability and compliance with international medical standards. This systematic packaging process, aligned with GMP standards, ensures traceability, batch integrity, and the highest level of hygiene before the products reach end-users.

This careful, standardized packaging guarantees that every blood collection tube maintains its sterility and performance from our facility to the patient, delivering reliable, safe products that healthcare providers can trust.
