VICI: Engineering the future of chromatography for 50 years Understanding how products are applied in the real world is the key to knowing how to make improvements.


Founder and President of VICI and its associated companies VICI DBS, VICI Valco, VICI Metronics, Precision Sampling, and VICI AG, Stan Stearns began his career in science right after university as a chemist in a crime lab and then in chromatography doing service and applications for Wilkins in 1965. When the company was purchased by Varian, Stan Stearns saw an opportunity to cross his real world experience from the Crime Lab with the technical knowledge he gained at Wilkins to invent solutions that would make an impact across industries. Long nights experimenting with the analytical instruments he was working with led him to discover new ways of applying and eventually improving them.


This insatiable curiosity began with improving valves, quite literally driving analytical science to go where it never had been before. Over the next 50 years this entrepreneurial spirit would pioneer the development of more effi cient components and instruments, with VICI eventually producing more than ten thousand different parts and products, still unrivalled in selection and technological reach.


“Chromatography is the science of separations, and is used in so many industries. Chromatography (and therefore the use of our products) is used by scientists and doctors from so many different industries, but common thread is...discovery, using our products, to get results. VICI products are driving progress in the pharmaceutical industry, in drug testing and safety, used for purity in the oil and gas industry, in space exploration for air/sample testing, in the proteomics industry for to help fi nd cures for diseases, and in Homeland Security to help identify harmful substances and keep people safe who are traveling and in crime and forensics labs to help solve crimes.”


What began as Valco Instruments in 1968, became VICI (Valco Instruments Company Incorporated), a legacy dedicated to analytical science 50 years later. VICI Valco Instruments are always being improved to help drive progress across industries.


In 1968 Stan Stearns was adding internal zero volume fi ttings to Valco’s product offerings at a time in chromatography when the common practice was to solder tubes into ports. Having encountered far too many incidents with soldered tubes that caused problems for customers, Stan noticed that it was the manufacturing process that introduced abrasives into the tube that could not be gotten rid of completely. Once the abrasives got into the system, they would destroy the expensive components. In addition, the customer would also end up having to twist the tubes leading to leaks down the road.


Our values are in our valves. Here are some of our products and their benefi ts.


Chromatographic multi-sample valving apparatus Benefi t: Saves time, energy and effort


Adaptor assembly for fi ttings and connective lines of differing sizes Benefi t: allows for one hand assembly method, making connecting lines of different sizes easier to accomplish


Sample introduction apparatus for gas chromatographic analysis using packed or capillary bore open tubular columns and method of testing Benefi t: Improve accuracy and simplify processes of using smaller sample sizes


Variable tensioning system for shear seal valves Benefi t: lengthens lifetime of valve and reduces chance of damage (better use of product translates into savings of customer in both downtime and money)

Pressure insensitive mass fl ow controller EL-FLOW®


Prestige, the newest generation of Bronkhorst Mass Flow Meters/


Controllers for gases, can now be equipped with an on-board pressure sensor. In combination with the ‘Differential Temperature Balancing’ sensor technology and an incorporated gas database with physical properties, the instrument automatically compensates for inlet pressure variations. As a result, the accuracy and control stability will not be affected by these pressure changes. Next to an improved yield of the customer’s process, additional components for line pressure control will no longer be required.


The Multi Gas / Multi Range functionality of the EL-FLOW® Prestige enables the user


to select any of the installed gases and to adjust the measuring range within the boundaries of the device. Also the dynamic behaviour of the mass fl ow controller can easily be tuned on site, by adjusting the controller speed parameters. These settings can be changed using our free software tools FlowTune™ or FlowPlot™. The last mentioned tool can also be used for device diagnostics or alarm and counter settings.


A line of viscosity baths designed to accommodate specifi c testing and quality control needs, including ASTM D-445, is available from PolyScience. Confi gured for use with most popular capillary viscometers, these versatile circulating baths feature working temperatures up to 150°C, temperature stabilities to ±0.01°C and glass or polycarbonate reservoirs. Four different controller types, from an innovative touch screen model with time/temperature programming capability to an extremely affordable digital temperature controller, are available. All models include a tap water cooling coil.


PolyScience’s Polycarbonate Viscosity Baths feature a 29 litre rectangular reservoir with a working depth of 11.25 inches (28.6cm), square or round viscometer openings, and may be equipped with the Advanced Programmable, Advanced Digital, or Standard Digital Temperature Controller. The maximum working temperature for these baths is 85°C.


PolyScience Glass Viscosity Baths are available with either 17 or 27 litre round reservoirs and are equipped with multiple controller options for varying requirements. These baths feature round viscometer openings, working depths of 11 inches (27.9cm) and 17 inches (43.2cm) respectively, and have a maximum working temperature of 150°C.

Halo is working 24/7 to clean the air in the lab. Once vapours are detected, Halo will capture them in Erlab’s proprietary carbon fi ltration technology. After adsorbing the molecules that cause unwanted odours, clean air is returned back to the room through low-disruptive side vents.
