The N 820.3 FT.40.18 is a two-stage pump with an integrated “self-drying” system for automatic conde (more)nsate 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, condensation may form 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.

KNF UN816.3KT.45P IP20-T Diaphragm Pump Ultimate Vacuum 20 mbar (abs.) Maximum Flow Rate 16L/min (1 (more).8 m3/h) Protection Class IP20 Features - Small footprint - Clean, 100% oil-free operation - Corrosion-resistant - Vacuum gauge and regulator for simple, convenient control - Compact, quiet and reliable - Can handle wet vapors without damage - Maintenance-free TheKNF UN816.3KT.45P IP20-T Diaphragm Pump isa single-head, dry-running device used in a wide range of laboratoryapplications. They transfer, compress and pump down without contamination. Theheart of these very compact pumps is a KNF structured diaphragm. This patenteddiaphragm was stress-optimized using the Finite Elements method. As a result,KNF was able to make the pump smaller while increasing the service life of thediaphragm. This pump is 115V. INCLUDED: The KNF UN816.3KT.45P IP20-T Diaphragm Pump includes: - Power Cord - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty

Heidolph Hei-FLOW Ultimate 600 Peristaltic Pump The ability to switch between precise dosing and fas (more)t conveying make this pump model the perfect complement to a reactor system. With a flow rate of 2.0 - 4,056 ml / min, when operated with single-channel pump heads, flows from feed-batch and chemostat modes of operation can be conveyed precisely. Rapid filling and emptying of the reactor system is also possible. In addition to the selectable process parameters - speed, tubing diameter, flow quantity display, dosing volume, interval dosing and break times - the pump conveying characteristics are stored in the program. Thanks to the analogue and digital (RS 232) interfaces, processes can be automated. All media is conveyed with a control accuracy of ±2% at a speed of 24 — 600 rpm. An optional foot switch can be connected for dosing by foot pressure.

Edwards XDS35i Dry Scroll Pump Ultimate Vacuum 1 x 10-2 mbar Inlet Connection NW40 Displacement 43 m (more)3h-1 / 25 ft3min-1 Features - Scroll pumps provide oil-free pumping, making them an excellent alternative to rotary vane pumps for clean applications - The XDS pumps feature an innovative bearing shield that isolates the vacuum environment from lubricants, ensuring a totally dry operation and protecting bearings from process gases - Adjustable gas ballast enhances vapor handling, allowing the pumps to be used in applications previously unsuitable for scroll pumps - Achieves a peak pumping speed of 35 m³/h (50 or 60 Hz) for rapid and effective operation - Capable of handling a maximum inlet pressure for water vapor of 35 mbar (23 Torr) - Operates at a nominal rotation speed of 1750 rpm for consistent performance - Exceptional leak tightness of <1 x 10⁻⁶ mbar ls⁻¹ for reliable and efficient operation Edwards XDS35i Dry Scroll Pump Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The XDS pumps in particular use an innovative bearing shield to isolate the vacuum environment from all forms of lubricant not only making them totally dry, but also protecting the bearing from any process gases. Vapour handling is enabled by an adjustable gas ballast; this allows the range of pumps to satisfy many applications that were previously off limits to other scroll pumps.
