Mini process probe.
Company Description
Hellma GmbH & Co., founded
in 1922, is the world market
leader in cells, fiber optic
probes, and optical components
made of glass or quartz
which are used for modern
optical analysis. Hellma
Analytics products are available
worldwide through a network
of Hellma Analytics sister companies
and additional
distribution agents.
Major Products/Services
Complete traceability and excellent reliability of measurement
results — with UV–vis calibration standards
from the accredited DKD calibration laboratory of
Hellma
With the accreditation according to DIN EN ISO 17025, Hellma
Analytics is one of the leading accredited calibration laboratories
that produce and certify liquid and glass calibration filters made
for testing spectrophotometers. Increased security and quality
demands among laboratories require an improved traceability
of measurement results to an internationally approved standard.
An accreditation according to DIN EN ISO 17025 ensures the
traceability of calibrations carried out to references of the NIST, by
which an international correlation of measurement results is
assured. Thus, procedures in laboratories gain greater transparency
and improved protection of their measurement results.
Fiber–optical systems
The development of fiber-optical systems has caused a small
revolution in chemical analysis. This technology makes it possible
to carry out photometric measurements not only under
laboratory conditions with cells, but also outside the lab.
Through the development of fiber-optic probes, analysis has
moved directly to the process for measurements with continuous
measurements possible without sampling. This allows for
better control of ongoing processes with much less effort.
TrayCell — Micro Volume Analysis for sample volume
of 0.5 µL to 10 µL
Even in classical analysis the specialists at Hellma Analytics are always
setting new standards. One of the most recent examples: the
fiber-optic ultra-micro measuring cell “TrayCell,” which allows accurate
analysis of DNA, RNA, or proteins in sample volumes of as
low as 0.5 μL. The dimensions of the TrayCell are equivalent to a
standard cell in order to work in all common spectrophotometers.
Features:
⦁ Unique fiber optic ultra-micro measuring cell
⦁ Works with 0.5 μL to 10 μL sample volume
⦁ A single drop measuring sample is
sufficient
⦁ High precision and reproducibility
⦁ Dilution is not necessary
Modern Flow Cytometry requires
highest standards
The heart of every flow cytometer is a
small quartz glass flow channel providing
reliable stability of the fluidic system and
precise optical analysis of single cells. Due
to sophisticated technologies Hellma is
able to manufacture customer specified
channel dimensions down to 50 μm ×
50 μm with any outside dimension and
highly polished surfaces.
Custom Designed Products
In addition to the large range of standard
products, Hellma Analytics also manufactures
special cells and other precision optical
parts according to customer’s specifications.
Hellma Analytics has more than 90 years
experience in the field of glass machining
and fabrication. Our specialists can carry out
complex tasks and give full and competent
advice regarding design ideas and any
alternative possibilities.
Analysis in space — processing at
the cutting edge of technology
A close collaboration with research institutes,
universities, and scientific institutions is
important for Hellma Analytics’ outstanding
engineering competence. Based on this
extensive know-how in processing
techniques, Hellma Analytics is able to find
unique solutions. Excellent examples of
achievements are the individually designed,
custom-made cells being used in the
International Space Station (ISS) or those
which were used in physics research that led
to the winning of the Nobel Prize in 1997
and 2001.
