KNF LABOPORT N 820 G Diaphragm Pump

This listing is for 1 of 2 Watson Marlow 520S Peristaltic Pump. The unit is in full working conditi (more)on and is ready for immidate realese. Peristaltic pumps are the simplest possible pump, with no valves, seals or glands to clog or corrode. The fluid contacts only the bore of a tube, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. Peristaltic pumps can operate dry without risk. Easy to install, simple to operate and inexpensive to maintain, peristaltic pumps are ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. Suitable for metering, dosing and dispensing applications.   520S drive offers manual control via a large-key membrane keypad: speed adjustment; run and stop; forward/reverse; "Max" key for rapid priming and purging.   Supply voltage/frequency: 100-120V/200-240V 50/60Hz Flow rates from 4 microliters/min up to 2.4 liter/min Precise 2,200:1 speed control range from 0.1 to 220 rpm in 0.1 rpm increments Large speed/flow display and easy to use tactile membrane keypad. Incorporates keypad lock Manual control and flow rate calibration MemoDose for accurate single shot dispensing

VACUUBRAND ME 1C Chemistry Diaphragm Pump Ultimate Vacuum 100 mbar / 75 torr Maximum Pumping Speed 0 (more).5 CFM at 60Hz Number of Heads/Stages 1/1 Features - Convenient, quick and simple to use due to the new top-mounted power switch. - Whisper quiet and very low vibration. - Requires minimal benchtop space. - Maintenance-free drive system and proven long diaphragm life. - High chemical resistance. Vacuum filtration is one of the most common applications used for sample preparation in chemistry, microbiology, waste water control and other analytical processes. The ME 1C diaphragm pump offers a compact, high performance and easy-to-use solution which is perfect for single filtrations. This development, based on the highly successful technology of the oil-free diaphragm pump MD 1C, provides a well-proven and extraordinarily long diaphragm life time. The functional, space saving and innovative design with easily accessible, top-mounted power switch ensures convenient and quick operation for day-to-day lab work. Robust PTFE diaphragms and valves provide optimal chemical resistance. A manual vacuum regulator valve with dial gauge for adjustment of pumping speed and ultimate vacuum is available as accessory. One-stage diaphragm pumps are an excellent solution for continuous, oil-free pumping of gases and vapors with a modest vacuum requirement. In contrast to water-jet pumps they do not consume water and therefore do not produce any contaminated waste water in daily use. Typical applications for the ME 1C are filtrations and solid phase extractions with solvents. At a process vacuum of 100 mbar, 90% of the atmospheric pressure is available as the driving force for the application. If a certain pressure difference must not be exceeded, the pump can be equipped with an optional manual vacuum regulator valve with dial gauge. It enables continuous adjustment of pumping speed and ultimate vacuum. INCLUDED: The VACUUBRAND ME 1C Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

Heidolph Rotavac Valve Tec Ultimate Vacuum 12 mbar Suction Capacity 0.75 m³/h Nominal Rotation Spee (more)d 1,800 RPM Features - Recommended for solvents with low or medium boiling points - Vacuum can be controlled through valves or manual vacuum controllers - A vacuum valve is necessary if you wish to combine this vacuum pump with Hei-VAP Expert Control/Ultimate Control rotary evaporators All components that come in contact with media are made from chemically resistant fluoropolymer. The durable PTFE design guarantees a superior diaphragm lifespan. Head cover and clamping disc have a stable core made from metal that offers unsurpassed long-term performance. The direct pump drive (without belt) has no wear parts, is exceptionally quiet and creates a very low vibration environment. The physically optimized gas ballast valve prevents from condensate collecting in the pump. Condenser is not in scope of delivery. INCLUDED: The Heidolph Rotavac Valve Tec includes: - Power Cord - Operator's Guide - Full 3 Year Manufacturer's Warranty

Ohaus heavy-duty orbital shakers These models are designed to handle a wide range of applications, e (more)nsuring constant orbital shaking. Digital models offer accurate speed control for applications that require repeatable results. - Includes a tray and a rubber mat; over 70 accessories as an option - Maintenance free motor - Protect your samples. The increase function allows a gradual increase of the speed up to the set point, to avoid splashing. If so, a sensor detects the unbalance of the load and slows down the speed reaching a safer one Applications Cell cultures, solubility studies, extractions, suspensions and bacterial and yeast cultures, dyes / bleaches, immunoassays, protein studies, absorption techniques Display Easy-to-read independent LED displays with speed and time information, allowing the operator to view both settings simultaneously Operation Detachable three-wire cable and plug (included) Communication The RS232 interface provides one-to-one communication for data collection and unit control Structure Cold Rolled Steel (CRS) Construction features Integrated tray (279 x 330 mm) with non-slip rubber mat included.

Heidolph 036110235 Hei-PLATE Mix 'n' Heat Expert Basic Sensor Package, 135mm Plate Temperature Range (more) 20 to 350°C Speed Range 100 to 1,400 RPM Stirring Capacity 20L Features - Comprehensive safety features including large safety distance and visual residual heat indicator - Automatic stir bar detector for hassle-free operation - Rotational direction setting for optimal sample mixing - Three-stage setting for stirring speed startup behavior - Programmable ramps and individual profiles for increased precision and reproducibility of experiments - Compatible with Pt1000 temperature sensor and double sensor for simultaneous measurement in sample and bath liquid - Three heating modes: FAST for quick heating, PRECISE and PRECISE+ for exact temperature control without overshoot - Multiple interfaces to ensure compatibility with your lab's data management system The magnetic stirrer Hei-PLATE Mix 'n' Heat Expert convinces with its intuitive handling: Thanks to respectively one display per main function (stirring and heating), you have an easily legible eye on all values and settings at any time. The handling is made via two push-and-rotary controls with LED-rings for an easy identification of the active functions. Separate timers for heating and stirring functions create flexibility and let you control your experiments better. The user-friendly menu navigation makes working with this device particularly easy. For controlling the temperature, you can choose between three heating modes: FAST for a particularly quick heating, as well as PRECISE and PRECISE+ for a particularly exact control of your target temperature without overshoot - this is how sensitive samples are optimally protected. Therefore, the device is compatible with the temperature sensor Pt1000 as well as the double sensor Pt1000 that allows the measurement in your sample and in the bath liquid simultaneously. For the stirring speed, there is a three-stage setting (start-up behavior). Furthermore, you can set the rotational direction of the magnetic stirring bar and benefit from the automatic stir bar detector. As a result, your sample is optimally stirred at any time, even when there are irregularities while stirring. This magnetic stirrer is equipped with the most important safety features. The large safety distance between the heating plate and the control panel, as well as the visual residual heat indicator at temperatures 50 °C, protect against burns. The patented Kera-Disk® plate made of anodized aluminum is chemical-resistant, scratch-resistant and has a diameter of 135 mm. This makes it suitable for the use with many accessories and samples on a small footprint. Moreover, the material used allows the fastest heating times.Click Here to View Product Video INCLUDED: The Heidolph 036110235 Hei-PLATE Mix 'n' Heat Expert Basic Sensor Package, 135mm Plate includes: - Magnetic Stirrer Hei-PLATE Mix'n'Heat Expert (135 mm diameter) - Pt1000 Temperature Sensor - Power Cord - Operator's Manual - Manufacturer's Documentation - 10 Year Manufacturer's Warranty
