12 October 2021 — Linkam Scientific Instruments, expert in sample characterization, has launched a new Water Circulation Pump (WCP), designed specifically to provide optimized water cooling to its range of temperature and environmental control stages. When used with Linkam’s Peltier stages, the WCP is able to hold sample temperatures as low as -30°C (with an ambient temperature of 21°C). The WCP also provides cooling to high temperature stages running up to 1500°C.
A pressure optimized fan coupled with a full copper radiator makes for efficient heat dissipation and quiet operation. A brushless DC-motor circulates the water around the system, providing increased pumping performance, allowing the WCP to be positioned further from the stage where required without performance losses.
The unit constantly monitors the fan speed, pump current and water temperature and, when used with LINK software or the LinkPad, will stop the run if any of these parameters stray outside of the safe values to prevent damage to the equipment. The cooling efficiency of the system means the contained water volume is only 300ml, giving users peace of mind if it is close to electrical equipment.
With a footprint of only 360 x 80mm, the new WCP fits easily into the most space-limited labs and can be placed neatly alongside the Linkam controllers, positioned underneath the work surface, or up to three meters away from the stage.
Duncan Stacey, director of sales and marketing, commented: “We have developed the WCP specifically for use with our range of temperature-controlled stages and it offers users several advantages over the current options. The water pump it replaces, the ECP, is large and bulky, requires a lot of water and is impractical to fill, with spillages a common frustration. The WCP is compact and efficient, practical for use in the lab and can be controlled remotely.”
The WCP is compatible with a wide variety of Linkam products, from the Peltier stage range, for improved low temperatures, to the High Temperature TS range (TS1000, TS1200, TS1500, HS1500), for efficient cooling of the stage body and other products that can be used above 300°C, such as the THMS600, LTS420 and DSC450. It can be controlled remotely with Linkpad or LINK software and starts automatically with the experiment. The WCP is also compatible with many third party devices.
