Edwards Silencer for nXDS and XDS5/10 Dry Scroll Pumps-cover
Edwards Silencer for nXDS and XDS5/10 Dry Scroll Pumps

Edwards Silencer for nXDS and XDS5/10 Dry Scroll PumpsFeatures - Compact design combines both filtra (more)tion efficiency and noise reduction - Integrated inlet diffuser optimizes sound attenuation - Multi-stage noise reducing features including final stage sound absorbent insert - Tubular silencing design - tube is positions to maximize attenuation and air flow while minimizing pressure drop - Patented high grade element with built-in butterfly gasket seal which creates positive seal between housing hemispheres and a new seal with each element - Seamless drawn housings - no welds to rust or vibrate apart - Durable carbon steel construction with black powder coated finish - Ability to mount vertically or horizontally The Edwards Silencer for nXDS and XDS5/10 Dry Scroll Pumps has two main functions: to reduce exhaust noise during pump down and gas ballast operation as well as to collect and retain tip seal dust as the pump is operated. Exhaust gases exit the exhaust port when the pump is being used to evacuate a process chamber, or when the gas ballast control is being used, or both. The noise level when pumping down rises as the throughput increases and the silencer is used to reduce this noise level. The outer can is made of pressed steel and is split to allow access to the filter elements. The filter element housing is made from Santoprene thermoplastic elastomer. The element itself is polyester. The foam block is manufactured from filter foam. INCLUDED: The Edwards Silencer for nXDS and XDS5/10 Dry Scroll Pumps includes: - NW25 Clamp - Centring Ring - Manufacturer's Documentation - 1 Year Manufacturer's Warranty

Heidolph 036110230 Hei-PLATE Mix 'n' Heat Expert Hotplate Stirrer, 145mm Plate-cover
Heidolph 036110230 Hei-PLATE Mix 'n' Heat Expert Hotplate Stirrer, 145mm Plate

Heidolph 036110230 Hei-PLATE Mix 'n' Heat Expert Hotplate Stirrer, 145mm Plate The Heidolph 03611023 (more)0 Hei-PLATE Mix 'n' Heat Expert Hotplate Stirrer, 145mm Plate convinces with its intuitive handling: Thanks to respectively one display per main function (stirring and heating), you have an easily legible eye on all values and settings at any time. The handling is made via two push-and-rotary controls with LED-rings for an easy identification of the active functions. Separate timers for heating and stirring functions create flexibility and let you control your experiments better. The user-friendly menu navigation makes working with this device particularly easy. For controlling the temperature, you can choose between three heating modes: FAST for a particularly quick heating, as well as PRECISE and PRECISE+ for a particularly exact control of your target temperature without overshoot - this is how sensitive samples are optimally protected. Therefore, the device is compatible with the temperature sensor Pt1000 as well as the double sensor Pt1000 that allows the measurement in your sample and in the bath liquid simultaneously. For the stirring speed, there is a three-stage setting (start-up behavior). Furthermore, you can set the rotational direction of the magnetic stirring bar and benefit from the automatic stir bar detector. As a result, your sample is optimally stirred at any time, even when there are irregularities while stirring. This magnetic stirrer is equipped with the most important safety features. The large safety distance between the heating plate and the control panel, as well as the visual residual heat indicator at temperatures 50°C, protect against burns. The patented Kera-Disk® plate made of anodized aluminum is chemical-resistant, scratch-resistant and has a diameter of 145 mm (also available with 135 mm on request). This makes it suitable for use with many accessories and samples on a small footprint. Moreover, the material used allows the fastest heating times.
