Shedding Light on Microreactors

Traditionally, most students have learned about chemical reactions in laboratories using test tubes, beakers and flasks. Those who have gone on to discover and develop new products have typically done so using these batchwise techniques. This mind-set has continued through…

Process viscous material with this kneading extruder

The Conterna (photo) is a continuous kneading and extrusion machine designed for processing highly viscous materials, such as plastic compounds with a high percentage of fillers. Besides plastics, the Conterna is also used in the food and chemical industry for…

This microfluidic chip offers rapid fluid mixing

The glass Mitos Micromixer Chip (photo) is designed for the rapid mixing of two or three fluid streams. Compatible with the Mitos four-way edge connector, this novel chip enables extremely rapid mixing across a wide range of flowrates. This chip…

Achieve lower air leakage with these rotary valves

Newly designed rotary valves for pneumatic conveying of granular products feature expanded tips at the ends of rotor blades to reduce air leakage. The valves have an increased number of blades, as well as redesigned air vents to help minimize…

Enhanced graphical software for better welding

Swagelok New software has recently been released for this firm’s welding system M200 power supply (photo) to deliver increased performance and an updated graphical interface. The portable M200 is easy to use and offers 200-A capability for orbital welding at…

These regulators suppress internal cylinder forces for safety

ESAB Welding and Cutting Products Purox and Oxweld oxygen cylinder regulators (photo) have a patented design that suppresses internal forces from a cylinder explosion within the cylinder walls. The design minimizes risk of injury in the event of an explosion.…

A wide range of gear pumps gets extended even more

Michael Smith Engineers The established range of Viking External Gear Pumps (photo) has been extended to include models that provide flows from as little as 0.2 L/min up to 760 L/min. Available from this firm, the SG range now includes…

This gas seal exhibits a self-cleaning effect

Cartex GSDN bi-directional gas-lubricated seals can be used to standardize new centrifugal pumps or recondition existing pumps that have conventional stuffing-box packings or liquid-lubricated mechanical seals. The characteristic design feature of the Cartex Series is a seat and shaft sleeve…

Eccentric-disk pumps can be used for abrasive, thick or thin fluids

The Mouvex SLC-Series eccentric-disk pumps are designed to self-compensate for mechanical wear and maintain consistent flow over time. With seal-less construction, low shear and agitation of the pumped product, the ability to run dry for up to five minutes and…
