Lazar Scientific, Inc
12692 Sandy Drive, Suite 116 , Granger, Indiana, United States

Lazar Scientific, Inc. sells and services laboratory instruments for testing the physical properties of jet fuel, diesel, gasoline, marine fuels, biofuels, lubricating oils, greases, and crude oil. Many of our test instruments also lend themselves to specialty chemicals, adhesives, flavors and fragrances, inks, coatings, and paints. Our extensive product line includes instruments for testing flash point, viscosity, cloud and pour points, freezing points, distillation, corrosion properties, fuel cleanliness, density, refractive index, polarity, penetration and oxidation stability; among others.  Instruments we sell and service include flash point testers, distillation analyzers, viscometers, RVP analyzers, FAME in Jet Fuel Analyzer, H2S in liquids analyzer, refractometers, density meters, and elemental analysis by MWDXRF technology.  Our manufacturing partners include Stanhope-Seta Co., Seta Analytics, Tannas Co., King Refrigeration, Orbis BV, XOS, Schmidt + Haensch, and PSL-Rheotek.

Defining how clean or dirty fuel is,

is critically important in today’s world. Modern fuel injection systems and electronic unit injectors operate at very high pressures and the components have very fine tolerances. At these pressures and at high temperatures the injectors can suffer abrasive wear from fine particles and water that may be present in the fuel.

Pure Biodiesel,

sometimes referred to as FAME (Fatty Acid Methyl Esters), or B100, are specified in ASTM D6751.  Blends of B100 with petrodiesel (ASTM D975) are named based on the percentage of B100 in the blend, ie B6 is 6% B100 to 94% petrodiesel. The ranges of B6 to B20 are in specification D7467. Each of these specifications has a slate of tests that may be performed to qualify the fuels. We carry instruments and manual apparatus for many of these tests.

The properties of Crude Oil

vary greatly depending on where in the world it is coming from and how it is extracted.  This is even truer today with the development of extreme processes of extraction such as fracking. Also, due to the fact that some of these fields are in remote locations, transportation of crude oil has become more complex; including pipelines, rail transit and truck tankers. Testing for properties such as vapor pressure, flash point and H2S content is very important for transportation safety concerns. Other methods; such as distillation, sulfur content, chlorides content and carbon content are important factors for determining the optimal processing parameters for producing usable products from the crude; with the least potential damage to refining equipment.

There are many applications for Diesel Fuel;

truck fuel, diesel automobiles, off road and power generation to name a couple. The use of diesel is growing, particularly with the advent of clean burning diesel automobiles. The developments being made to produce more efficient and cleaner burning engines has made cleanliness particularly important.  Diesel fuel can be produced over a wide spread of boiling ranges, impacting the properties of the finished products leading to widely different characteristics.  Diesel fuel in the US is specified in ASTM D975. It lists seven different grades of diesel and specifies test limits for each of them.

Gasoline in the United States

is specified in ASTM D4814.  It is also regulated closely by the US EPA, particularly for vapor pressure and sulfur content, among others. Requirements for RVP (Reid Vapor Pressure) are defined by region and switch between a summer grade and winter grade.  Below are some of the methods commonly used for testing gasoline:

Lubricating Oils

There is no petroleum product perhaps with more complexity in specification than lubricating oils. Part of the reason for this lies in the large variety of applications for lubricating oils.  Another is the variety of properties needed depending on which application the lubricant is being designed for. In automotive lubricants alone there are varying grades which have to balance such needs as wear, piston deposits, fuel economy, oxidative stability, sludge and seal compatibility. There is no one ASTM specification for lubricating oils.  SubCommittee B is responsible for test methods for passenger car motor oils; but the actual specifications are developed by other industrial organizations and car manufacturers.
