Laboport SD N 860.3 FT.40.18 is a two-stage pump with an integrated “self-drying” system for automat (more)ic condensate drain. The “SD” series is widely used in laboratories, especially when the vapors are humid and a clean and ecological vacuum is required. Typical applications are: vacuum ovens (for drying chemicals, drying biological samples, heat treatments), autoclaves for sterilizing instruments, containers, filters and textiles. Thanks to the use of anti-corrosion materials, it is possible to vacuum even corrosive products. The heart of the pump is the diaphragm with differentiated structure in PTFE, optimized to guarantee high performance with reduced dimensions and at the same time, long life even in heavy applications. When the humid gases are sucked in, it can happen that condensation forms in the pump head: consequently the performance decreases, considerably increasing the emptying time. To eliminate condensation, the 'drying system' then opens a solenoid valve that allows ambient air to enter the heads. Once the condensation has been eliminated, the solenoid valve closes and the pump sucks from the stove in full capacity. Over time, condensation could form again and then the cycle is repeated. The time interval between one cycle and the next can be adjusted as desired, as well as the duration of the air injection.

Ultimate Vacuum 1x10-3 mbar Inlet Connection NW25 Displacement 25.0 m 3h-1 / 14.7 ft 3min-1 Features (more) - High ultimate vacuum and rapid pumping speed make it the industry standard for laboratory and light industrial applications - Quiet operation ensures a comfortable working environment, reducing noise in sensitive areas - Freestanding design with a flexible coupling driven by either a single-phase or three-phase (four pole) air-cooled motor for versatile use - Supplied with essential accessories, including 2 x 1 liter of Ultragrade 19 oil, O-ring and centering ring, two Allen keys, and spare seals for oil drain and filter plugs - Features a pressurized oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces for reliable performance - Includes an oil distribution valve to prevent oil discharge to the pump interior after stopping, enhancing safety - Airtight pumping chambers prevent suckback unless the gas ballast valve is open, maintaining system integrity - Facilitates easy oil changes with an oil drain-plug for gravity or pressure oil drainage Edwards E2M18FX Vacuum Pump 115/230V The EM range of oil sealed rotary pumps – renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour – have become the industry standard for laboratory and light industrial applications. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single phase or three phase (four pole) air cooled motor. Each EM pump is supplied with 2 x 1 litre of Ultragrade 19 oil, O ring and centering ring, two Allen keys and spares seal for oil drain and filter plugs. For PFPE prepared FX pumps Fomblin® to be ordered separately. This is a single stage oil sealed rotary vane pump which has a pressurised oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior after the pump stops. The pumping chambers are air-tight, so this arrangement also prevents suckback unless the gas ballast valve is open. You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has an oil drain-plug to allow either gravity oil drain or pressure oil drain.

The LC-NMR-MS Interface is designed to sit between an HPLC system, an NMR spectroscopy probehead and (more) an MS unit. It would normally be mounted on top of the MS table immediately in front of the MS input connector. The BNMI-HP consists of 3 medium pressure (> 60Bar) syringe pumps, a 1:20 splitter, an 8-Port valve, 3 mixing chambers (T-Pieces) and associated control and interface electronics. The flow of the HPLC separations to the MS unit can be modified by pumping additional solvent from the syringe pumps. This improves the MS peak detection and shortens the time needed for the split separation to reach the MS. Separations can also be stored as a result of an MS peak detection as well as through UV absorption peak detection. The splitter splits the fluid flow from the HPLC in a 1:20 ratio. i.e. ca. 5% of the fluid is directed to the MS and the remainder to either the NMR probehead for immediate analysis or to the BPSU36 storage cassette for storage and later analysis.  The fluid directed to the MS is mixed in the mixing chamber (T-Piece) with the solvent pumped from the syringe pumps. The two left hand syringe pumps pump alternatively to guarantee a constant ’makeup’ flow. The 3rd pump at the right hand side is used to pump a calibration fluid into the flow path to allow the MS to be calibrated (or simply synchronized) at the start and end of each measurement cycle. The 8-Port valve is used to direct the fluid flow. Control of the BNMI Unit is performed using the HyStar program via an ethernet interface. Commands received from HyStar are interpreted in the BNMI Control Board. The control board then sets up the BNMI unit accordingly e.g.: Starts the pumps, changes the flow rate, turns the 8-Port valve. The splitter has a fixed mechanical function and cannot be controlled or adjusted. It simply accepts a fluid flow and splits it into 2 paths in a 1:20 ratio. However, other split ratios are available (for example 1:100 may be preferred if you have very high sample concentrations).
