MWV Healthcare expands preservative free pumps line

The PFP products protect medicines from contamination. They include a combination of a formulation without chemical preservatives, a pump system that filters or blocks the returning air, and an actuator that prevents bacterial ingress into the dispenser.

MWV says the five-fold mechanical protection system assures germ-free pump dosing to the patient. It includes non-return valves next to the orifice bore and in the metering chamber, and a filter element for contamination-free ventilation of the container, a locked actuator, and a sealed air path during storage.

The PFP T delivers volumes from 0.05mL to 0.14mL. Upside down and tamper-evident features are also available with the product.

‘We are expanding the range of preservative free pumps to meet consumer demand for preservative-free formulations,’ said Chris Hall, vice president and managing director, Medical Plastics Division, MWV Healthcare.

‘This technology does more than protect preservative free medicines from contamination, it is also suitable for use with other topical or dermal products where protecting the formulation and maintaining sterility is important, and necessary.’
