Jurgen Semmer - new MD Shimadzu Europa

Jürgen Semmler

Shimadzu, one of the world leaders in analytical instrumentation, has appointed Jürgen Semmler as the new managing director of its European organization from July 1, 2021. Previously, head of Shimadzu Deutschland, he succeeds Jürgen Kwass, who led Shimadzu Europa from 2003 to the present and is now retiring. Semmler and Kwass have both been affiliated with Shimadzu for a long time and joined the company in the second half of the 1980s.

Jürgen Semmler graduated in chemical engineering at Essen University, Germany, before joining Shimadzu in 1987 as an HPLC service engineer. He gained international experience as a European team member in the development of a global software and since 1996 as manager of the European Customer Support Center. In 2006, he was then appointed Managing Director of newly founded Shimadzu Deutschland. Under his management, the company has grown from 60 to more than 150 employees, and its sales from €19 million to over €40 million. Previously independent companies were incorporated into the organization as technical offices under the overall management of Shimadzu Deutschland.

Thanks to Jürgen Kwass

As Shimadzu Europa and Shimadzu Deutschland are both based in Duisburg, Germany, the two Managing Directors have always worked closely together.

Semmler commented: “Under Jürgen Kwass’ aegis, Shimadzu’s network was rolled out to every European country and set up structurally and in terms of staff to serve the customer needs of medium-sized companies as well as global players. Shimadzu’s growth is closely linked to his commitment and name.”

Shimadzu Europa has been active on the continent since 1968. Its medical and laboratory solutions are used in health care, the latter primarily in science and technology, particularly in almost every manufacturing industry such as chemicals, pharmaceuticals and biotechnology, food and beverage, advanced manufacturing, automotive, semiconductors and plastics. They serve consumer, patient and environmental protection as well as process and quality control.

Future development and growth trends

With regard to technical trends, such as automation, miniaturization of systems, digitization and hyphenated techniques, ABC has provided significant impetus to the market and initiated developments in recent years.

Semmler noted: “Digitization in particular holds both technological and creative potential. In analytical instrumentation and medical technology, it facilitates seamless workflows as well as simpler, more accurate and faster measurements and tests. It also enables analytics and medical technology to merge to deliver solutions for the most challenging medical conditions, such as the diagnosis and treatment of cancer or dementia.”

Shimadzu Europa is Shimadzu’s oldest continental foreign organization and plays an important role in the company’s growth and globalization process.

Semmler said: “In addition to our technological expertise, we also want to continue to strengthen our presence and network on an organizational level throughout the European region, expand our teams, and increase sales and market share. I am looking forward to the tasks ahead.”

Porvair microplate sealer

Porvair introduces entry level semi-automatic microplate sealer

Porvair microplate sealer

Designed to be simple to operate, the new Ultraseal LITE semi-automatic microplate sealer from Porvair Sciences is the perfect device for labs with low to medium throughput (6 plates / minute) processing needs.

Compact in design, the Ultraseal LITE will fit just about anywhere you need to use it – be it on a lab bench or inside a fumehood.

Combining a powerful 400W heater with a strong sealing action, the Ultraseal LITE is able to ensure high integrity  sealing of almost any type of microplate including deep well, shallow well, low profile deep well, filter and assay plates that conform to the ANSI / SLAS standard format.

The Ultraseal LITE utilises heat seal films and foils to give either permanent or peelable seals for all common microplate material types (polypropylene, polystyrene, polyethylene).

A typical sealing time for most polypropylene plates using Porvair seals is less than 3 seconds each. Seal times and seal temperatures are fully adjustable using the Ultraseal LITE control touch screen. Sealed plates are automatically ejected from the Ultraseal LITE.  

The Ultraseal LITE has dual voltage capability, allowing it to operate on both 120 and 240 volt alternating current, 50/60 Hz mains supplies without the need for a power transformer.

Ziath uses Artificial Intelligence to facilitate empty well detection

Ziath reports on the development of Artificial Intelligence that enables discrimination between empty wells in sample tube racks from wells with a tube present which may have an obscured or poorly rendered barcode.

This work, done in conjunction with the University of Hertfordshire (UK), is part of a program of development for the next generation of Ziath barcoded tube scanners due to launch around the end of 2021.

Ziath has implemented the new Empty Well Detection feature in the latest version of its popular DP5 control software to give customers the full benefit of the new technology immediately.

The company specialises in development of innovative instrumentation control and information management products using 2D Data Matrix bar-coded tubes to simplify automation processes in life science organisations, from academia, to the biotech and pharma industries.

DataMatrix barcodes play a key role in tracking and tracing both biological and compound samples. These barcodes are usually laser-etched onto the underside of sample tubes, and the tubes are then stored in racks. Tube identification using a barcode reader that scans the bottom of the rack and decodes all the barcodes in one go has recognised issues with correctly identifying which location has a tube and which is an “empty well”.

Ambient lighting, background image noise, variation in barcode lasering and material quality all contribute to detection difficulties using traditional machine vision techniques. To further improve sample tracking and tracing – the next generation of tube scanners and readers must be able to genuinely discriminate between empty wells and wells with a tube present which may have an obscured or poorly rendered barcode.

Dr. Alexander Beasley, from the University of Hertfordshire, is an expert embedded systems design engineer with experience in machine learning. Working closely with Ziath, Dr. Beasley has used a Convolutional Neural Network (CNN) technique for feature extraction of images from a Ziath camera-based barcode reader. In this developmental project he has applied CNN to discriminate empty wells from full wells in DataMatrix-barcoded tube racks.

“The CNN I have chosen is designed to be very lightweight allowing for quick execution. When compared to the pre-existing heuristic methods, the CNN approach was almost ten times faster to execute with virtually 100% accuracy,” Dr Beasley explained.

Neil Benn, Managing Director of Ziath, said: “This is just the first deliverable from our collaboration with Alexander and the University of Hertfordshire team. We are expecting this project to revolutionise the way we decode DataMatrix tubes and help us produce the next generation of faster, lighter, go-anywhere tube rack readers. It’s an exciting development that will, very soon, improve sample tracking and tracing for scientists everywhere.”

Discovery shows human cells can write RNA sequences into DNA

Cells contain machinery that duplicates DNA into a new set that goes into a newly formed cell. That same class of machines, called polymerases, also build RNA messages, which are like notes copied from the central DNA repository of recipes, so they can be read more efficiently into proteins.
