Hamilton Company Brand Guidelines: Clark Hamilton’s Microliter Syringe, Reno & Bonaduz

A chemical engineer and a syringe for tiny volumes.

Hamilton Company traces its start to a garage in Whittier, California, in the late 1940s. The published history of its Swiss sister company says Clark Hamilton, a young chemical engineer and a graduate of the Massachusetts Institute of Technology, was looking for a way to handle tiny quantities of fluid and ended up developing the microliter syringe for chromatography. A 2011 company profile in the chromatography journal LCGC describes him as an engineer from Nebraska and dates the first Microliter syringe to 1947.

Sources give different founding years. The company’s history gives 1950 as the year Clark Hamilton founded Hamilton Company; a 2007 “Corporate Retrospective” in LCGC says “the early 1950s”; an LCGC company listing from around 2010 gives 1953; and the 2011 profile says he founded HAMILTON Inc. in Whittier in 1955 so that he could make and sell the syringes under his own name. The retrospective credits Clark Hamilton with the first glass syringe that could repeatedly deliver microliter volumes accurately, and ties it to the arrival of gas chromatography: Clark Hamilton and his staff worked with chromatography pioneers such as Leslie Ettre and Keene Dimick, it says, and the syringes became an integral part of that growing field, and later of high-performance liquid chromatography.

The company says it outgrew the family garage in 1960 and moved into its first rented premises. In 1970, still under Clark Hamilton, the American company moved from Whittier to Reno, Nevada, where it is still based. Four years later he handed management to his son Steve Hamilton, who ran the business with the help of his brothers, according to the company’s history, which adds that the Hamilton companies “remain in family ownership to the present day.”

From the syringe to the pipetting robot.

From syringes, the range widened. The 2007 LCGC retrospective lists the first digital diluter for diluting samples before injection, a digital syringe, polymer-based reversed-phase HPLC columns and laboratory robotic systems that automate sample transfer, preparation and introduction into chromatographs. The LCGC listing from around 2010 adds pipettes, dispensers, valves and syringe pumps, and names manufacturing sites in Reno and in Bonaduz, Switzerland, with sales offices in France, Germany and the United Kingdom. It also says instrument makers often use Hamilton fluid subsystems in their own machines.

Automation became the company’s second identity. Under Steve Hamilton, the company says, it developed its first pipetting robots, with the Swiss site leading that work from 1974. One current robot line is the Microlab STAR, which Hamilton’s product listing on SelectScience describes as automating liquid-handling tasks “from simple to complex.” The company says its robotics unit grew strongly in the pandemic years of 2020 and 2021, when its pipetting robots were set up for large-scale PCR testing.

Hamilton has also bought and built for ever smaller volumes. In December 2022 the life-science news site Bionity reported that Hamilton was acquiring BioFluidiX, a microdosing company in Freiburg, Germany, founded in 2005, whose patented processes dose liquid in the nanolitre and picolitre range; the BioFluidiX brand was to be kept and the Freiburg site expanded, with a move planned to an innovation centre on the University of Freiburg campus. In November 2024 the Greater Zurich Area investment agency reported that Hamilton and CSEM, the research and development centre in Neuchâtel, had developed a liquid-analysis system based on microfluidics and optical image analysis, now marketed as VeriPlate: CSEM developed the microfluidic plate, while the robotic pipetting integration and the image analysis came from Hamilton’s development laboratories.

Design and documentation.

Laboratory automation is sold to scientists, and its makers tend to present it in a laboratory register: white or pale grey instrument decks, pipetting heads lined up over microplates, racks of tips and plates picked out in colour, and clean benches with little else on them. Product photographs usually show the machine from the front or from above, so that the layout of the deck, the channels and the labware can be read at a glance.

Software is part of the picture. Pipetting robots and plate handlers are run from method editors and touchscreens, and makers often show those screens next to the hardware, with protocol steps, plate maps and progress bars set in plain sans-serif type. The pairing lets a single page show both the instrument and the way it is run.

Many of the companies began with a single hand instrument and grew towards automation. Hamilton’s history starts with a glass microliter syringe of the late 1940s; INTEGRA Biosciences grew from a Zurich firm founded in 1965 into a maker of electronic pipettes and benchtop robots. Acquisitions of smaller specialists, in microdosing or in digital microfluidics for sequencing, have pushed the same businesses towards ever smaller volumes.

The trade meets at fairs and conferences such as SLAS, the meetings of the Society for Laboratory Automation and Screening, and analytica in Munich, where makers show their instruments to laboratory buyers. Several of the makers in this round are Swiss or have Swiss sites, while others are based in the United States or the United Kingdom; their guides set those shared conventions against very different histories and owners.

One family name on two continents.

Hamilton grew on two continents. The company’s history says Clark Hamilton founded Hamilton Bonaduz AG in 1966 at Bonaduz, in the Swiss Alpine canton of Graubünden, to sell microliter syringes more easily in Europe; the 2011 LCGC profile instead describes a subsidiary set up in Chur in 1962 that moved to neighbouring Bonaduz five years later. The first Swiss chief executive, Max Wälchli, ran the Swiss business for 35 years, the company says. From the 1980s the Swiss side branched out: Hamilton Medical AG, a ventilator maker, was founded in 1983, and a process-analytics unit making pH sensors followed in 1989, built on the same skills in glass and precision measurement as the syringes. Andreas Wieland led the Swiss companies from 2001 to 2021, a period in which, the company says, their workforce grew from about 350 to about 1,600.

Further sites followed. The company says it founded Hamilton Storage in Franklin, Massachusetts, in 2007 to make automated sample-management systems, with a Swiss Hamilton Storage company following in 2015; opened a second European production site in Timișoara, Romania, in 2013, where microliter syringes, needles, valves and pipetting modules are made; and built a production plant at Domat/Ems, next to Bonaduz, in 2018, where ventilators and sample-management systems are produced. Taken together with the LCGC listing, the company’s own account places its production in Reno, in Graubünden and in Romania, with the BioFluidiX operation in Freiburg. The name is shared with other businesses, among them the Hamilton watch brand; this guide covers only the laboratory company of Reno and Bonaduz.

For a design guide, Hamilton Company shows how a business built on one precise glass instrument can carry a single family name across syringes, robots, sensors and storage systems for more than seven decades. Compare Gilson, the maker of the Pipetman pipette, and INTEGRA Biosciences, the Swiss pipette and robot maker based at Zizers. For this guide we use a deep slate blue, a cool steel grey and a warm amber on an off-white ground with a sans, an unofficial interpretation; no product or logo is reproduced.
