Cole-Parmer pump head

Edwards RV3 Vacuum PumpFeatures - The RV is a truly versatile pump for operation throughout for your (more) operations, perfect for wet applications, dusty applications and clean dry applications. - The RV series of pumps has the highest vapour handling capacity of any rotary vane pump. This is ideally suited for your wet pumping applications such as freeze drying, extraction, filtration and gel drying. - The best-in-class anti-suck back protection prevents dust or oil mist from entering your system. The fast-acting automatic inlet valve acts within 0.4 seconds. - The universal motor in the pump covers the widest possible voltage and frequency range from a single motor. - You can service and replace parts without dismantling the pump mechanism. All parts self-align, eliminating the need for special assembly. Pump valve has "controlled" opening on power startup so that the system vacuum will never see a pressure surge on startup The RV uses a high-quality "universal" motor to cover the widest possible voltage and frequency range. A one-size Allen key is used to dismantle all parts of the RV pump. All rotor and stator parts are completely interchangeable The RV series of small oil sealed rotary vane pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapour handling capabilities with quiet operation. With over 300,000 units produced, these pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications. All RV pumps are approved to UL and CSA standards by an external test house and feature our unique mode selector switch, meaning one model is suitable for both high vacuum or high throughput applications.

VACUUBRAND MV 2 NT Diaphragm Pump Ultimate Vacuum 0.5 mbar Max. pumping speed at 60 Hz 1.4 cfm Num (more)ber of Heads/Stages 4/4 Features - Outstanding chemical resistance and superior vapor tolerance - Exceptionally high performance even at low vacuum - Compact design - Whisper quiet and very low vibration - Long diaphragm life, maintenance-free drive system Four-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases when the need is to reach fractional millibar ultimate vacuums. All parts in contact with pumped vapors or gases are made of aluminum, stainless steel and carefully selected plastics suitable for a wide range of non-corrosive applications. The new NT-series pumps provide whisper-quiet and ultra-low-vibration operation, high leak-tightness and improved vacuum. The highly flexible, fabric-reinforced double diaphragm made of FKM offers extended operating life. Four-stage diaphragm pumps are an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases under the very high vacuum demands of applications in physics and analytics. Due to the outstanding ultimate vacuum, these pumps are often used as alternative to rotary vane pumps. A typical application is the use as backing pump for turbomolecular drag pumps.INCLUDED: The VACUUBRAND MV 2 NT Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

Motic SMZ-171-TP Stereo Trinocular Microscope Magnifaction Range 7.5x - 50x Standard Working Distan (more)ce 110mm Optical System Greenough Features - Stereo microscope - Trinocular head - Greenough optical system - 7.5x - 50x standard magnification - 110mm standard working distance - Plain pole type stand The Motic SMZ-171-TP is a stereo microscope, featuring high quality Greenough optics. Designed for versatility, the SMZ-171-TP can be used in a variety of fields, from medical applications to industrial quality control. This rugged microscope is built to provide clear and distortion free images through many years of daily use. In its standard configuration, the SMZ-171-TP has a working distance of 110mm, providing ample room for dissection instruments and sample manipulation. Working distance refers to the amount of space between the unit’s base and the unit’s objective, and is an important feature of any stereo microscope – the larger this number, the more room users have to operate. Magnification is controlled by a zoom knob on the microscope’s side, enabling users to adjust between 7.5x and 50x in one continuous motion. The zoom knob also contains five indents, so that precise magnifications can be quickly and accurately repeated. This is especially important when taking measurements with micrometers, reticules, and processing software. Motic also offers a wide variety of optional objectives and eyepieces, greatly expanding the magnification range from 2.25x to 200x. The SMZ-171-TP is presented in a modular format and can be easily modified by the user. A large number of optional illumination sources, stands and filters are available, enabling users to customize the scope to suit their specific application. It is also available in both binocular and trinocular formats. Digital documentation of your work is made simple with any of Motic’s digital microscopy cameras – the Moticam. With over 20 models to choose from, these range from standard resolution, to research grade instruments with integrated cooling devices.INCLUDED: The Motic SMZ-171-TP Stereo Trinocular Microscope includes: - 10x Eye Piece - Power Cord - Operator's Guide - Manufacturer's Documentation - 5 Year Manufacturer's Warranty
