Description

Welch DryFast Collegiate Diaphragm Vacuum Pump, Model 2047B-01, maximum vacuum 30 Torr and 2.5 CFM flowrate. Diaphragm Vacuum Pumps use a flexible expanding pocked, one directional (one-way) valves, and a lifting mechanism such as a rocking piston to expand and collapse the diaphragm pocket and move gas. This gas movement is what creates the vacuum. This particular Diaphragm Vacuum pump uses chemically resistant fluorocarbon materials in the construction of the pump components; this results in a vacuum pump that is highly resistant to chemicals and chemical attacks from corrosive liquids and vapors, acids, bases, alcohols, solvents, and thinners. This feature makes this particular vacuum pump a popular choice in Laboratory Applications.

Some of the advantages and features of this vacuum pump are chemical resistance, Oil-Free, no need for lubrication, and no need for maintenance, the vacuum is adjustable and high flow. Common applications include but are not limited to: Vacuum filtration, SPE(Solid Phase Extractions), Rotary evaporation, Rotary Evap of low and high volatile solvents, Vacuum ovens, Automated systems, Aspiration, DNA pelleting, Centrifugal concentrators, Multiple user filtration / utility vacuum network.

PTFE Diaphragm Vacuum Pumps enable precise vacuum control for organic evaporations with exclusive Advanced Vapor Management (AVM).

Vacuum Decay Leak Testing Systems
Vacuum Decay Leak Testing Systems are Instruments that detect and quantify a leak by measuring the drop in vacuum (pressure) inside the specimen. During a vacuum decay leak test, the specimen is placed into a vacuum chamber, the vacuum is pulled to a specified setpoint, and the drop in vacuum is monitored and recorded over time. If a leak in the specimen exists, the air will travel from a higher pressure (inside the specimen) to a lower pressure (vacuum chamber). As a results of the additional air, the vacuum levels will drop whereas a leak can be detected and quantified.
Rotary Vane Vacuum Pumps
Rotary Vane Vacuum Pumps are the most widely used vacuum pump in the industry. When it comes to performance at a reasonable price, rotary vane vacuum pumps are the way to go. Many Rotary Vane Pumps can achieve 2 to 5 milliTorr vacuum rating at a good volumetric flowrate (2 to 20 CFM) at a very reasonable price (hundreds to a few thousand dollars)

Have you ever wondered how the weather forecast works? You must admit; the weathermen (or weatherwoman) have become a whole lot more accurate over time. 10 years ago, the weather forecast was not as accurate as it is today. Part of the reason is that we have better forecasting technology as in more powerful computers who crunch numbers faster to out a most likely scenario. Another reason is that mathematics, physics, and science has progressed. The main reason however, is that we have better tools and equipment.
