Laboratory Products 33 Pipetting Solutions for Cell Culture Workflows
The biophysics research team at the University of Bayreuth has been taking advantage of the most popular and unrivalled pipette controller, Integra’s PIPETBOY acu 2, for the preparation of buffers, media and samples in its cell culture workflows, simplifying culture set-up, splitting and media exchange. Technical assistant Andrea Hanold explained: “Our main area of research focuses on what influences intracellular transport, internalisation processes, and how the cell organises itself. Much of my work involves cell culture workflows, which can be performed far more precisely and efficiently using the PIPETBOY. We’ve had two PIPETBOY acu 2 pipetting aids for about 10 years, and these are always in constant use, one shared by everyone in the wet lab and the other used exclusively for cell culture.
“The challenge with pipetting for cell culture in a biosafety cabinet is maintaining a sterile environment, which means being careful not to reach over anything. With the PIPETBOY, I can just use one hand to safely pipette as much liquid volume as needed without interruption, simply by pressing one button to accurately aspirate and another to dispense. It’s easier to use than Peleus balls or pipette controllers from other suppliers that I’ve used in the past. This makes a huge difference, and has improved the team’s pipetting experience. It also saves us precious time and increases productivity in the lab, while mitigating any errors to enhance the accuracy and reliability of our results. We’ve only ever had to replace a single rechargeable battery in 10 years, and everything else is still working wonderfully - they’re almost indestructible.”

The Advantages of Viscosity Measurement Innovation
The EMS-1000S is an innovative viscometer that employs the ‘Electro Magnetically Spinning’ method. A small aluminium spherical probe is placed inside a sample and spun through the Lorentz force. The rotational speed of the probe at a given temperature is measured and is used to calculate the sample’s viscosity. Samples are measured using cost-effective, disposable tubes and probes, meaning contact-free measurement, zero clean up and no risk of equipment failure when using samples that harden during measurement. The autoclavable tube suits sterile samples and can be hermetically sealed for measurement under anaerobic conditions. The EMS-1000S can measure samples as low as 90µL in volume, ideal for the analysis and reuse of scarce and expensive samples. The instrument can maintain samples at between 0 to 200ºC (stability: ±0.1ºC), and by utilising the appropriate probe for your sample, can measure in the viscosity range of 0.1 to 1,000,000mPa·s, accommodating low viscosity samples and eliminating the need for different rotors. Parameters can be set in the accompanying software for the analysis of shear rate and temperature dependence of viscosity in real-time. All these features and advantages translate to the EMS-1000S having great applications for the research and development of ionic liquids (e.g. low viscosity assessment over wide temperature range in inert gas conditions), pharmaceuticals/diagnostic agents (e.g. concentration dependence studies of sterile protein samples), polymer and petroleum products (e.g. temperature dependence of viscosity), food products (e.g. viscosity and texture/mouthfeel, viscosity during thickening and gelatinisation), and more.
