VACUUBRAND MZ 1C Chemistry Diaphragm Pump Ultimate Vacuum 12 mbar / 9 torr Maximum Pumping Speed 0.5 (more) cfm at 60Hz Number of Heads/Stages 2/2 Features - Outstanding chemical resistance and superior vapor tolerance. - Convenient, quick and simple to use due to the top mounted power switch. - Optimized vacuum even with gas ballast for continuous purge. - Whisper quiet and very low vibration. - Maintenance-free drive system and proven long diaphragm life. Chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors. The two-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum. All major parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE-sandwich diaphragms increase reliability and extend operating life. The MZ 1C pump is equipped with a gas ballast valve for continuous condensate purge increasing the pumping capability of condensable vapors. It features slim design for space-saving installation and good vacuum performance. A manual vacuum regulator valve with dial gauge for adjustment of pumping speed and ultimate vacuum is available as accessory. Two-stage chemistry-design diaphragm pumps are an excellent choice for continuous, oil-free pumping of gases at medium vacuum requirements. In contrast to water jet pumps, they do not consume water and therefore do not produce any contaminated waste water. Typical applications are rotary evaporators, gel dryers, filtrations and many other lab applications. The MZ 1C is a powerful pump for smaller vacuum apparatus enabling continuous pumping of solvent vapors. It´s a compact, stand alone pump with low ultimate vacuum. If the process requires atmospheric condensation of pumped vapors or electronic vacuum control, we recommend the pump families based on the MZ 2C NT or MD 1C. INCLUDED: The VACUUBRAND MZ 1C Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

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

Nanocolor Quattro thermoreactor. Four constant temperatures: 70 / 100 / 120 / 148 °C. Capacity for 8 (more) round glass tubes of 14 mm ID (16 mm OD) and 2 reaction tubes of 22 mm external diameter possibility for the selection of 4 times: 1/2, 1, 2 hours and continuous operation. Safety mechanism to prevent overheating. Specifications:

The HX5.EX scale is a modern weighing instrument assuring fast and reliable measurement in hazardous (more) areas classified as zones 1/21 and 2/22. To ensure precision and excellent measurement repeatability, high quality electronic components are used. The weighing platforms offered in wide range of dimensions and maximum capacities, this combined with excellent metrological parameters enables easy selection of an instrument that meets the most demanding requirements. Standard version of the scale is equipped with 2 serial, intrinsically safe RS232 communication interfaces, and with one RS485 interface. They facilitate cooperation with equipment intended for operation in hazardous areas. Possibility to add digital inputs/outputs extends the range of instruments compatible with the indicator by automatic elements compliant with ATEX directive. More demanding customers can use the IM01.EX module, installed in the safe area, which extends the available connectors by Ethernet, USB, 4-20mA/0- 10V analog outputs, Profibus DP and additional digital inputs/outputs. This enables cooperation with external devices: barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control and superior IT systems. Scale operation requires use of a dedicated PM01.EX power supply, which is not a standard scale component. To operate the scale, order a selected type of the dedicated intrinsically safe power supply. Power supply types: PM01.EX-1 - power supply for operation in ATEX area. Used when it is required to connect the power supply to voltage source placed in hazardous area. PM01.EX-2 - power supply for operation outside ATEX area. Used when power supply connection to voltage source is carried out outside hazardous area. Complex software enables carrying out many tasks connected with mass measurement, e.g. parts counting, checkweighing and statistics. The scales feature user-friendly graphic interface, which can be customized using widgets. This and the large colour display of high resolution guarantee easy and clear transmission of data on current process. Colour bar graph significantly influences performance by signalling whether the weighing result is within declared thresholds or not. The frame for recessing (foundation) is part of the set – you will receive it with the ordered scale.
