There are numerous types of laboratory vacuum pumps. There are laboratory pressure pumps as well as laboratory compressor type pumps. The most commonly used pumps are piston vacuum pumps, diaphragm pumps and carbon vein pumps. New Star offers all three types of pumps. We sell these pumps through laboratory equipment suppliers or directly through the New Star website.
Vacuum pumps have many uses in the chemistry labs including rotary evaporation, vacuum manifolds, filtration, vacuum chambers and roughing, glove boxes, and cell culture. Laboratory vacuum pumps are exposed to critical type gases calling for chemical duty PTFE vacuum pumps (oil free), but most laboratory applications serve the standard duty dry vacuum pumps. Laboratory application often call for various flow ranges and the ability to maintain pressure drop, therefore it is important to select the proper pump. New Star Environmental offers a full line of laboratory vacuum pumps that meet these requirements.
The Importance of the Right Vacuum Pump
Laboratory equipment such as vacuum pumps, filters and their accessories are vital to a full functioning laboratory. New Star supplies the multi-branch manifolds, the membrane filters for the manifolds, the torches and all accessories needed to complete lab experiments.
It is important to remember the laboratory piston pumps are meant to run for shorter time frames and ideal for most lab work, but if you require extended sampling time you should consider diaphragm pumps or vein type pumps. New Star handles the full Welch pump line in addition to the Rocker series pumps. Rocker pumps have diaphragm type pumps for the 24/7 type applications. but New Star also has the Fischer vacuum pump series.
Rocker Vacuum Pumps for Your Lab
Rocker laboratory piston pumps are ideal for aqueous solutions and buffers. Rocker vacuum pumps can be converted to pressure pumps or commonly known as compressors type. The standard duty dry piston pumps are effective for filtering solutions that are not strongly acidic or basic. We also carry PTFE vacuum pumps for acid type gases. Rocker pumps come with pressure gauges , liquid traps, liquid shutoff and run at very low noise levels and are ideal for filtration for suspended solids and microbiology. They are clean and maintenance free. The vacuum pumps can handle multiple type manifolds.

Particle counting is necessary to make cellphones or laptops function properly. These, and many more devices, run on semiconductors which are manufactured by semiconductor companies in clean-rooms with strict standards for air quality.
A clean-room is a work area with an extremely low level of environmental pollutants. The level of contamination in a clean-room must be controlled to conform with a predetermined number of particles per cubic meter, with no particle exceeding a specified size. It is the task of particle counting that ensures compliance with these standards. A clean-room can be as large as an entire factory where the air from the environment is processed to filter out contaminants then recirculated through high efficiency particulate or ultra-low particulate air filters.
Its unique design enables rotary vane pumps to become variable displacement pumps. By allowing the centerline distance from the rotor to the eccentric ring to change, the displacement of rotary vane pumps can be altered. This allows rotary vane pumps to even pump in reverse by moving the ring far enough. This characteristic makes rotary vane pumps efficient hydraulic oil control pumps and energy saving devices.
The transportation industry is a major beneficiary of rotary vane pumps. Moving automatic transmission, power steering and brake fluids are among the most common uses of rotary vane pumps in cars. For large diesel trucks, rotary vane pumps are used as vacuum pumps for additional braking power. Most light aircraft use rotary vane pumps to drive the gyroscopes in flight instruments, altitude and heading indicators. Low-pressure gas applications such as exhaust emission controls use rotary vane pumps to provide secondary air injection.

Piston pumps operate using the basic principle of the piston transferring force from a crankshaft to the piston in order to compress or eject a gas or liquid. The liquid or gas enters a suction manifold into a chamber where it is compressed by a piston and then discharged. Common applications of piston pumps are to power pneumatic drills, blow PET plastic bottles, water pumps, hand pumps and pressure washer pumps such as those used in a car wash.
Because of their relatively simple, rugged construction and design versatility, piston pumps have become a work horse for many industries. They can take a wide range of pressures which can be controlled without affecting the flow rate. If the valves are correctly designed, piston pumps can work with solids, viscous liquids and gases. Changes in the pressure and discharge rate do not adversely affect the performance of piston pumps. With the proper use and maintenance, piston pumps can be a reliable partner for a long, long time.

We Carry Every Type of Particle Counter
You need to keep your laboratory clean and ensure that the particle level in the environment is correct for your needs. Our particle counters are some of the best in the industry and effectively measure the number of particles in the air or in a liquid to ensure optimum health conditions and clean liquid so that machines to not break down.
We carry the perfect types of particle counters for your needs including the following:
- Remote Particle Counters – small units fixed in a specifiec location that simultaneously monitor the air quality 24 hours a day.
- Handheld (portable) Particle Counters – These convenient, but powerful and accurate, particle counters can be moved around from one location to another. Hoewver, due to lower flow rates, longer sample times may be needed in order to certify a cleanroom. Yet, handheld types are proven to be just as reliable as the larger models.
Particle counters work by using a process of either light scattering or light obscuration to detect the presence of particles and measure their size. The air or liquid is passed through a chamber where a light source, usually a laser, detects the presence of a particle. In the light scattering process, particle counters redirect the light to a photo detector which then measures the size of the particle. In a light obscuration process, particle counters detect the loss of light which forms the basis for determining the size of the participle.
By detecting the presence and counting the size of particles in the air, particle counters determine the quality of the air. This tells us whether the air is safe to breathe or if it conforms with cleanliness standards of a specific work area, known as cleanrooms. Particle counters are also used to detect and measure the particles in a liquid to determine whether it is safe to use in its intended application.

Particle counting is performed by sophisticated instruments known as optical particle counters. The most commonly used type of equipment for particle counting is a remote optical particle counter system. Small dedicated optical particle counters are installed in specified areas throughout the plant. These units are connected to a central control location which monitors the information gathered by the terminals, analyzes the particle counting information, issues alerts whenever there are deviations from standards, and directs the necessary remedial action.
A semiconductor plant will also make use of other types of particle counting equipment like handheld or portable optical particle counters. These are smaller, mobile units that can be used to periodically check parts of the plant where there are no fixed particle counting terminals.
Ensure that your environment has the correct particle count by viewing our extensive online list of particle counting tools today.
Used for small scale pumping applications, laboratory pumps have a lower pressure and volume capacity than the larger agricultural or industrial pumps. Laboratory pumps are lightweight, have a small footprint, use less electricity and are ideal for the low-pressure work in a laboratory. Aside from standard laboratory use, laboratory pumps are widely used in the biotechnology, pharmaceutical and food industries. They are also standard equipment for blood collection. Laboratory pumps may be either vacuum pumps, piston pumps, peristaltic pumps, impeller type pumps, air and membrane pumps.
We have all of the major types of laboratory pumps in our online store, including the following:
- Piston Laboratory Pumps – utilizing acuter motors that implement air pressure to do the pumping, these can be calibrated and are incredibly reliable in delivering the precise fluid amounts needed.

Learn Whether or Not You Need an Optical Particle Counter for Your Lab Setting.
An optical particle counter is a sophisticated instrument that detects and measures particles present in liquids and in the air. While liquid particle counters have many uses in industry, it is the aerosol particle counters that affects individual lives most of all.
An optical particle counter detects and measures particles by either light blocking or light scattering. As the air passes through a laser beam, particles in the air either block the light or scatter it. The amount of light blocked or scattered in an optical particle counter is picked up by a photo detector which measures the dimensions of the particles. By refraction and diffraction, an optical particle counter measures the size and number of particles present in the sample being tested.
