Description by the supplier

This second-hand system presents a remarkable performance profile, offering a displacement capacity of 3.7 m³/h at 50Hz and 4.5 m³/h at 60Hz. The speed achievable under the same conditions is 3.3 m³/h at 50Hz and 3.9 m³/h at 60Hz. It reaches an ultimate pressure of 2.0 x 10⁻³ mbar, while the ultimate pressure with the gas ballast is 3.0 x 10⁻² mbar.


The system is engineered to handle a maximum inlet pressure for water vapor of 80 mbar, with a maximum water vapor pumping rate reaching 60 g/h. The maximum allowed outlet pressure is calibrated at 0.2 bar, and it supports a maximum allowed inlet and gas ballast pressure of 0.5 bar. Operating at a nominal rotation speed of 1500 rpm at 50Hz and 1800 rpm at 60Hz, this equipment ensures efficient performance.


With a weight of 25 kg (excluding oil), the system allows for oil capacity ranging from 0.42 L to 0.7 L. Both the inlet and exhaust flanges conform to the NW25 specification, facilitating easy integration into existing setups. Operating at a noise level of 48 dB(A), it maintains a quiet working environment, suitable for research laboratories.

VACUUBRAND MZ 2C NT Chemistry Diaphragm Pump

VACUUBRAND MZ 2C NT Chemistry Diaphragm Pump Ultimate Vacuum 7 mbar (5 Torr) Maximum Pumping Speed  (more)1.4 CFM at 60Hz Number of Heads/Stages 2/2 Features - Outstanding chemical resistance and superior vapor tolerance - High performance even at low vacuum levels - Optimized vacuum even with gas ballast for condensate purge - Whisper quiet and low vibration - Long diaphragm life, maintenance-free drive system 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 parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms increase reliability and extend operating life. The pump MZ 2C NT is equipped with a gas ballast valve for continuous condensate purge increasing the pumping capability of condensable vapors. This pump is our most popular chemistry diaphragm pump, and is the heart of a family of VACUUBRAND pumping systems. The NT-series features further improved performance data and superior vapor tolerance. Two-stage chemistry-design diaphragm pumps are an excellent choice for applications with corrosive gases and vapors with medium vacuum requirements. They do not consume water and therefore do not produce any contaminated waste water. The media contacted materials made of chemically resistant fluoroplastics open a wide range of applications in chemistry and pharmaceutics. The robust design provides very good durability and long service intervals even in demanding chemistry applications. Typical usages are vacuum generation for rotary evaporators, vacuum concentrators, gel dryers, vacuum ovens and many other laboratory applications. The MZ 2C NT is the powerful basic pump for a complete family of well established and reliable chemistry vacuum systems and pumping units.INCLUDED: The VACUUBRAND MZ 2C NT Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

VACUUBRAND MD 1 Diaphragm Pump-cover
VACUUBRAND MD 1 Diaphragm Pump

VACUUBRAND MD 1 Diaphragm Pump Ultimate Vacuum 1.5 mbar (1.1 Torr) Maximum Pumping Speed 0.82 CFM a (more)t 60Hz Number of Heads/Stages 4/3 Features - Contamination-free pumping and evacuation - High flow rate even near ultimate vacuum - Excellent ultimate vacuum - Whisper quiet and ultra-low vibration - Proven long diaphragm life, maintenance-free drive system The MD 1 diaphragm pump is an excellent choice for oil-free evacuation and pumping of non-corrosive gases down to 1.5 mbar ultimate vacuum. The three-stage design with precisely guided flat diaphragms provides outstanding pumping speed even close to the ultimate vacuum, especially when compared with similarly rated two-stage diaphragm pumps. The MD 1 is an ultra-low vibration pump with very long diaphragm lilfetime and stable ultimate vacuum documented with years of testing. With a flow path consisting of aluminum and selected plastics (diaphragms and valves made of PTFE/FKM and FKM, respectively) the pumps are suitable for a wide range of applications with non-corrosive gases. The MD 1 is an excellent choice for continuous, oil-free evacuation and pumping of non-aggressive gases. It is suitable for high vacuum requirements at modest gas flow as often needed in physics and analytics. The pump is exceptionally quiet and reliable with long diaphragm and valve lifetimes. With its low ultimate vacuum and compact dimensions the MD 1 is widely used as replacement of rotary vane pumps. Typical applications are exhaust gas analysis, for degassing of small amounts of viscous media and in particular as backing pump for compact turbomolecular drag pumps. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation. For equipment manufacturers customized versions are available.INCLUDED: The VACUUBRAND MD 1 Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

Radwag E1 Mass Standard - Flat Polygonal Sheet - 100 mg-cover
Radwag E1 Mass Standard - Flat Polygonal Sheet - 100 mg

E1-class mass standards are the elite in the world of metrology, because standards of this class rep (more)resent the highest level of precision and accuracy in mass measurement. The E1 classification is one of the most stringent standards that standards must meet in order to be considered the most advanced and trustworthy measurement tools. E1 - class standard: flat polygonal sheet Nominal value: 100 mg Material: Stainless steel What Are the Characteristics of the E1 Class? Highest Precision - The allowable deviation from the actual weight is minimal, making standards of this class ideal for applications where every gram matters. Stability and Repeatability - This guarantees a consistent level of accuracy over the long term. Accurate Calibration - Standards of this class must be regularly compared with other standards of known mass to confirm their measurement accuracy. Materials with Unique Properties - E1 class mass standards are often made of materials with exceptional physical properties, which makes them stable and resistant to changes in environmental conditions. Application 1. Analytical Laboratories In analytical laboratories where accurate measurements are crucial, E1 class mass standards are used to calibrate balances with the highest precision. 2. Pharmaceutical Industry In drug manufacturing, where even the slightest deviation from the standard affects quality, E1 class mass standards are irreplaceable. 3. Scientific Research In scientific research, especially in areas requiring the highest precision, such as physics or chemistry, E1 class mass standards are used to ensure reliable results. 4. Metrology Industry In metrology laboratories where research on E1 class mass standards alone is carried out, E1 class standards are the standard of excellence. Class E1 mass standards are not only measuring tools, but also a symbol of metrological excellence. Their use affects the quality of measurements in various areas of life because they provide precision that can be relied upon. They are a key element in the world of mass measurement, shaping standards and raising the bar for all measurement tools.
