Description

Welch DryFast Collegiate Diaphragm Vacuum Pump, Model 2034B-01, maximum vacuum 9 Torr and 1 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.
Micro-D Vacuum Feedthroughs
Micro D Vacuum Feedthroughs are Micro D connectors rated for vacuum and are generally installed on the vacuum chamber wall. You can then connect from the outside to the inside of your chamber.
Our Work: Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials
This vacuum chamber is a modification to our basic acrylic vacuum chamber 12 inch, removable lid model; except that our customer requested additional ports and electrical feed-through for testing of electrical equipment under vacuum. You know, I wish we would have asked them for more details on what they were doing with this chamber; their short and concise answer was that they were using our chamber to perform scientific work on the subjects of: lithium ion batteries, thin films, fuel cells, super-capacitors, and nano-materials testing in a vacuum environment.

In the article we are going to cover rotary vane vacuum pumps. We will touch upon how they work, what they are used for, when to utilize a rotary vane vacuum pump, its advantages and disadvantages. Perhaps you have noticed that rotary vane vacuum pumps come in all shapes and sizes. On one website, the vacuum pump is less than a $100; on another website you see a vacuum pump quotes at $10,000. I would imagine that you immediately ask yourself what the deal here is.
