Science for Solids
The VERDER SCIENTIFIC Division of the VERDER Group sets standards in scientific equipment for quality control,
research and development of solid matter. The fields of activity cover sample preparation techniques as well as
analyzing technologies.
With more than 500 employees the companies of the division develop and manufacture laboratory
instruments for sample preparation through disintegration and homogenization, for heat treatment
(physical and material stress tests), for analyzing samples through particle characterization and for
elemental analysis by combustion.
This brochure introduces four members of the VERDER SCIENTIFIC Division who successfully share
distribution channels and key markets:
CARBOLITE, ELTRA, RETSCH and RETSCH TECHNOLOGY.
The VERDER SCIENTIFIC Division and VERDER LIQUIDS Division (fluid handling and pumping solutions) are the
core business units of the family-owned Dutch VERDER Group with more than 800 employees world-wide.

3. Development
2012
ELTRA and CARBOLITE enter the division. Their range of instruments provides a perfect match to the laboratory and
analytical product portfolio.
Cooperation for the mutual benefit of the companies under the VERDER SCIENTIFIC umbrella is established.
2011
Due to the continuous growth of VERDER SCIENTIFIC new and bigger facilities for R&D, production, shipping and
administration are built in the city of Haan near Duesseldorf (Germany).
1999
RETSCH TECHNOLOGY is founded. The new member of the VERDER SCIENTIFIC Division rapidly develops into one
of the world's leading companies for optical particle analyzers with Dynamic Image Analysis.
The focus of the SCIENTIFIC Division is set on developing new products and improving existing product lines.
1989
RETSCH — a world-renowned company for laboratory mills and sieve shakers — becomes part of the VERDER family,
extending the business activities towards scientific equipment. The first cornerstone of VERDER SCIENTIFIC is set.
The following years are characterized by global expansion, improving local service and reaction times for customers
all over the world.
1959
The young Dutch salesman André Verder starts trading pumps and semi-finished plastic products. André continuously
expands the activities by acquiring and setting up new members for the VERDER "family of companies".

6. Elemental
Analyzers
For more than 30 years ELTRA has been one of the
leading manufacturers of elemental analyzers.
Starting with combustion analyzers for
carbon and sulfur determination ELTRA has
extended its product range successively
with analyzers for oxygen, nitrogen and
hydrogen as well as thermogravimetric
analysis.

7. Chemical elements are the basic modules of the materials and
substances surrounding us. They influence material properties and
consequently the quality of substances.
ELTRA develops and manufactures combustion analyzers for the
reliable and rapid determination of carbon, hydrogen, nitrogen,
oxygen and sulfur in solids. Determining the elemental composition
is an important factor in the quality control and development of
materials.
Thanks to tailor-made solutions for a wide range of samples and
concentrations thousands of satisfied customers worldwide are proof
of the quality and reliability of ELTRA analyzers.
The instruments are used in industries such as steel production,
mining and coal industry, construction materials and in universities
for research & development, to name just a few.

11. Besides the focus on sample preparation of solids RETSCH has
developed a core competence in developing and manufacturing
instruments for particle characterization.
RETSCH sieve shakers, test sieves and evaluation software
provide the key to easy, rapid, reproducible and, above all,
accurate analyses.
RETSCH offers the most comprehensive range of sieving
machines with regards to sieving motion, measuring range and
sieve diameter, thus covering virtually any bulk material — from
agglomerating powders and solid rocks to grains and cereals, dry
or wet.
For decades, quality control laboratories as well as research and
development departments have trusted the reliable and proven
technology of sieve analysis.

in Particle
Sizing
RETSCH TECHNOLOGY develops and sells
state-of-the-art optical measuring systems
for the characterization of size and shape
of particles based on Dynamic Image
Analysis.

13. Although hardly ever noticed by the end consumers, particle size
analysis is a fundamental step in quality control.
For any type of bulk materials, millions of particle size analysis
processes are carried out every day, all over the world. These
measurements not only ensure that the coffee has the same rich
taste every morning, and salt and spices are properly mixed in our
lunch menu, but also that industrial production runs smoothly and
efficiently.
RETSCH TECHNOLOGY's Dynamic Image Analysers help to maintain
highest quality standards by employing a measurement principle
which is direct, faster, and more accurate than traditional particle
sizing methods.
Meaningful, statistically relevant information about the size and
shape of millions of particles can be obtained within a few minutes.
Customers are offered turnkey solutions which meet their analytical
requirements, often after individual consultation
and application sample testing at the in-house
application laboratory.
