Edwards E2M28 Rotary Vane Vacuum Pump, 230V, Cat. #: A37324930

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.

VACUUBRAND VACUU-PURE 10C Screw Pump Ultimate Vacuum 0.005 mbar (0.0038 Torr) Maximum Pumping Speed (more) 5.3 CFM Inlet/Outlet Connection Small Flange KF DN 25 Features - 10-3 mbar vacuum range - 100% oil-free - Chemically resistant - No wear parts The dry screw pump VACUU-PURE® 10C reliably delivers the benefits of oil-free vacuum technology in the pressure range of 10-3 mbar. The new vacuum pump combines three important benefits for the user: 100% oil-free, chemically resistant, and no wear parts. VACUU-PURE 10C is ideally suited for clean processes and the production of pure products. The screw pump is especially designed for processes in the vacuum range down to 10-3 mbar, however unlike other fine vacuum technologies it can be used across the entire pressure range from atmospheric pressure to its ultimate vacuum. At the same time, aggressive gases and vapors can be pumped without any worries because of the high chemical resistance. The use of a cold trap is no longer necessary in most applications. VACUU-PURE easily handles high vapor loads through its extraordinary condensate compatibility. Thanks to this capability, a gas ballast is unnecessary, avoiding associated disadvantages like the reduction in pumping speed and an increase in noise levels. The integrated regeneration mode enables rapid drying of the pump at the end of the process. This allows sample throughput to be increased significantly as compared to other pump technologies. INCLUDED: The VACUUBRAND VACUU-PURE 10C Screw Pump includes: - 2 x Centering Rings - 2 x Clamping Rings - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

Mass comparators of UMA 200 series stand for the highest standard of professional automatic mass com (more)parators. They provide comparison of 10 g – 200 g weights of E1 and lower classes. The device is equipped with 36 magazine positions allowing to deposit up to 36 weights. This solution allows to perform either comparison for complete set of weights carried out within one process or comparison for just a few weights of the same mass. Owing to elimination of human factor and with temperature changes and air drafts reduced to zero, UMA automatic mass comparators provide the highest possible measurement repeatability.

Bransonic accessories are designed to maximize theeffectiveness of your Bransonic baths. It is impo (more)rtant that parts do not reston the bottom of the bath, as it can inhibit the ultrasonic activity andpossibly damage the unit. A variety of perforated trays, mesh baskets, beakers,and support racks give you the option of direct or indirect cleaning. All fivemodels come with covers to allow the cleaning bath to heat up more quickly. Direct Cleaning Method - Suspends parts using a perforated tray, mesh basket, or a support rack. - Permits sound waves to penetrate directly to the parts. Indirect Cleaning Method - Suspends parts using a solid tray, or beakers with a beaker cover. - Ideal for cleaning small parts. - Discarded soil cleans easily from a beaker or solid tray. - Indirect method is ideal for sample preparation. Perforated trays, solid insert trays, and wire mesh basketshave built-in handles specially designed to prevent accessories from touchingthe tank bottom. Support racks allow total volume of the tank to be used whilekeeping parts, fixtures, or containers about 1/2" above the tank bottom. Supportracks also are useful as countertop drain racks, holding parts above thecountertop surface. For 8800 Series Ultrasonic Cleaner 5.5 Gallon.
