Dry Lubricant

MicroCare Medical, New Britain, CT, offers a dry lubricant that has been specifically engineered to improve the performance of medical devices. Used on a variety of applications including catheters, cutting tools, surgical staplers, and hypo tubes, Duraglide™ dry lubricant assists in reducing stiction (the combination of sticking and friction). Made with polytetrafluoroethylene (PTFE), it lowers surface-to-surface friction resulting in easier and more consistent movement of actuation-based surgical and medical procedural equipment. It enhances the operation of devices by reducing friction on moving parts that slide, pivot, or twist. MD&M West, Booth 8073

Media Isolation Valves

Media isolation valves from Clippard, Cincinnati, OH, are solenoid-operated devices that use a flexible diaphragm to isolate the actuation mechanism from the fluid path. Media isolation valves are commonly used for a wide variety of applications, including those that require precise, repeatable dispensing of media. All wetted areas of the valve are PTFE, making this series ideal for use with corrosive media. A one-piece valve stem functions as a sealing membrane while also supporting and centralizing the poppet in the seating area. The multi-functional poppet/diaphragm/stem results in a simplified design with fewer parts, longer life and zero dead volume. MD&M West, Booth 2342

Variable Dispense Pumps

Fluid Metering Inc., Syosset, NY, has introduced a series of variable dispense pumps. The compact, low-profile FVD series are designed to simplify fluidic architecture. The series combines priming or washing and a precise dispensing pump in a complete package. The patented CeramPump® design utilizes a single, dimensionally stable and chemically inert ceramic “valveless” piston liner set for precise fluid control. This series provides the ability to have a higher flow rate for priming the line and automatically adjusts to a small dispense volume ranging from liters to milliliters to microliters to accommodate the desired dispense or flows for any application.

PVC-Free Plastic Components

Raumedic, Mills River, NC, has developed a range of components made from alternative materials without plasticizers that can be used in transfusions, for pump applications, or in gravity kits for parenteral infusion systems, for example. For medical and pharmaceutical tubing, the company offers polypropylene and polyurethane, both of which are drug tolerable, although their use must be considered on a case-by-case basis before the products are developed. When a more cost-efficient alternative to soft PP and PUR is needed, a newly developed two-layer tubing made from EVA and styrene butadiene rubber (SBR) could be an alternative to PVC.
