Edwards XDS35iC Dry Scroll Pump Ultimate Vacuum 1 x 10-2 mbar Inlet Connection NW40 Displacement 43  (more)m3h-1 / 25 ft3min-1 Features - High ultimate vacuum and rapid pumping speed ensure efficient operation across a wide range of laboratory and industrial applications - Quiet operation provides a comfortable working environment, reducing noise in sensitive areas - Features a pressurized oil system that lubricates pump shaft bearings and rotor sealing faces for reliable performance - Maintenance is simplified with an oil sight-glass for easy monitoring of oil levels and conditions at a glance - Facilitates easy oil changes with an oil drain plug that allows either gravity or pressure oil drainage for convenience - Compact, freestanding design allows flexible use without the need for additional support structures - Ideal for use with analytical instruments, leak detectors, helium research, and for backing turbomolecular pumps, showcasing its versatility Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The XDS pumps in particular use an innovative bearing shield to isolate the vacuum environment from all forms of lubricant not only making them totally dry, but also protecting the bearing from any process gases. Vapour handling is enabled by an adjustable gas ballast; this allows the range of pumps to satisfy many applications that were previously off limits to other scroll pumps. The Edwards XDS35iC features Chemraz internal valves and stainlesssteel fittings for extra protection from the pumped media. The ‘C’ series isbetter designed for more aggressive applications as opposed to the standardseries.

NESLAB Coolflow CTF33 Refrigerated Recirculator Lab This item was removed from a university where it (more) was surplus to requirement. It is in good cosmetic condition and powers on, although we were unable to set the desired temperature due to a display fault. Therefore, it is listed as Spares/Repair.

The HX7.4N H scale is a device controlled by means of the PUE HX7 indicator, and it has been equippe (more)d with a 4-load-cell ramp platform made of stainless steel, AISI 304. This robust design facilitates weighing of heavy loads in humid environment. The ramps enable easy loading and unloading. Indicator with a colour 7” graphic display and a diode bar graph allow to observe visualisation of a current load mass presented in relation to the scale range or declared minimum and maximum thresholds. This makes the operation significantly easier. At the back of the housing there are hermetic connectors of RS232, RS485, USB and Ethernet communication interfaces, plus digital inputs/outputs and analogue output. This enables cooperation with external devices such as barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control and superior IT systems. With use of the bracket you can either place the indicator at any flat horizontal surface, or fix it to the wall adjusting the tilt respectively to suit your needs. The terminal's software allows carrying out processes such as weighing, parts counting, dosing, labelling, formulations and percent weighing. Indicator’s system of information is based on databases (users, products, weighings, packaging, formulations, customers) and ALIBI memory which guarantees stored data safety. Since the scale is equipped with a platform lifting system, you are kindly requested to order a transport box (OSB box for the platform) for it. The transport box is necessary for the safe and efficient transport and storage of the ramp scale with the platform lifting system. Please take this item into consideration when planning and placing your order. If you have any questions, the Customer Service Department will be happy to assist you.
