PTL: The leader in independent particle characterization services. We provide expert particle characterizations to clients in industry, scientific research and government.
PTL is a one-stop shop for particle characterization of all sample types: from wet to dry, from food to materials, from natural to synthetic and every type in between. Pharmaceutical, environmental, regulatory and law enforcement are only some of the industries we service.
PTL's analysts are as qualified and precise as the equipment we use to determine particle size, thermal analysis, powder rheology and more.
A PTL particle characterization test is free of all bias. Test instrumentation is always selected on the basis of merit, never due to business relationships with vendors. Our staff has one goal in mind: accurate particle characterization test results.
Our lab operating practices are in compliance with cGMP (Current Good Manufacturing Practices) as decreed by the FDA. We hold permits from the FDA, DEA and ATF, and are registered with the Illinois DNR (IL DNR).
PTL: The Leader In Independent Particle Characterization Services
PTL is the leading particle characterization research and advisory company in the United States. We work with major organizations across the private, public and scientific research sectors. Our scope, and expansive knowledge of particle technology allows us to address problems that no one else can, and provide insight and perspective necessary for our clients to make the right decisions. We have deep functional expertise in industrial sectors such as pharmaceutical, environmental, petroleum-chemical, beauty and cosmetics, manufacturing, and food and beverage. We are the recognized leader in particle characterizations, providing our clients with a broad range of expert services in particle size and count distribution, surface area and image analysis, thermal analysis, powder flowability, and method development, verification, and validation.
PTL provides only the most scientifically reliable and accurate particle characterization test results. Our expert analysts are as qualified and precise as the equipment we use to determine particle size, thermal analysis, powder rheology and more.
The Independent Perspective
A PTL particle characterization test is free of all bias. Test instrumentation is always selected on the basis of merit, never due to business relationships with vendors. Our staff designs all tests and selects from our wide range of instruments with one goal in mind: accurate, independent particle characterization test results.
Providing Regulatory Compliance
PTL particle characterization tests satisfy regulatory compliance requirements across a wide range of industry, public and scientific research sectors. We are a proven cGMP (current Good Manufacturing Practices) compliant laboratory, in accordance with 21 CFR, Part 210 and 211. Our facility is FDA registered and inspected, and we host over 30 audits per year from the world's largest pharmaceutical companies. We are DEA licensed and approved to handle Schedule II through V Controlled Substances, we hold an ATF permit for analyzing pyrotechnic, and we are registered with the Illinois DNR (IL DNR).
Comprehensive Problem Solving
PTL is a one-stop shop for particle characterization of the universe of sample types: from wet to dry, from food to materials, from natural to synthetic and every type in between. Pharmaceutical, environmental, regulatory and law enforcement are only some of the industries we service. We provide specific analysis to request, or we design the best analysis based on client need. With a broad selection of the newest and legacy equipment, PTL provides consulting and highly accurate testing for solutions based on particle size analysis, surface area analysis, thermal analysis, image analysis, dynamic viscosity measurement and more.
