Liquid Handling Solutions for Successful Cell Culture Workfl ows


Integra Biosciences offers a full range of electronic pipettes, pipetting robots and media dispensers tailored to allow gentle pipetting for cell- based liquid handling tasks. This equipment is designed to offer enhanced pipetting speed control, limiting the stress placed on cells during handling to improve cell viability. In the first of its cell culture series, Integra tackles the challenge of cell viability, offering guidance for choosing the correct tools to optimise cell culture techniques.


Many vital stages in the cell culture workflow require handling or mixing solutions with a pipette but, if not done with care, this can lead to the shearing of cells at the orifice of the tip. Exposing cells to shearing forces can result in cell lysis and cell death, significantly reducing cell viability and reproducibility. Experts at Integra have developed an extensive range of liquid handling products - from multichannel electronic pipettes to assisted robotic platforms - to help scientists reproducibly culture healthy cells. Electronic pipettes give scientists greater control during cell handling, ensuring consistent, clearly defined pipetting speeds to minimise shearing forces and reduce the influence of user technique as a potential source of variation. The company also offers its renowned GripTip pipette tips in various sizes and styles, including wide bore options with a larger orifice for cells to flow through, further reducing the shearing forces. These innovations are based on years of experience and an appreciation of customers’ needs, ensuring the company remains an all-around trusted supplier and partner for cell biologists.

Within the flow metering industry, wiring a flow meter is often second nature to experienced engineers and may seem intuitive for established customers. However, Titan’s flow meters are used throughout a wide variety of industries, processes and applications. New customers unfamiliar with flow metering solutions, may find themselves in turbulent water if the meters are wired incorrectly during the installation process.


To combat this problem, Titan Enterprises have released video tutorials illustrating correct wiring of their pulse precision flow measurement devices to support customers with the installation of flow meters into their applications.


The majority of Titan’s flow meters use transistors which can be damaged through simple wiring mistakes, resulting in a defunct meter before the customer has even started. By providing customers with clear visual methods of how to install a flow meter and correct wiring to the power source, customers’ time and money are saved for these preventable errors.


“Although all Titan flow measurement devices are supported with written data and instruction sheets, through our ISO 9001 examination of returns and call logs, we have found that a large percentage of flow meter installation issues result from mis-wiring,” stated Jeremy Thorne, Production Manager with Titan Enterprises.


Neil Hannay, Senior R&D Engineer at Titan Enterprises, commented: “For customers who are new to our flow meters, visual demonstrations for wiring the flow measurement devices will help to reduce simple errors that cost customers time and money.


“YouTube is a very accessible platform and is a great delivery method for Titan flow meter instructional videos. As we don’t carry out on-site flow meter installations ourselves, providing visual tutorials are a useful way to illustrate correct wiring methods which we anticipate will reduce the number of unnecessary returns and rebuilds.”


Video tutorials currently available on the Titan website include wiring requirements for: Titan’s beverage flow meter; Turbine flow meters within Titan’s 800 series, 900 series and FT2 flow transducers; Titan’s OG2 oval gear flow meter.


These flow metering instruction videos will be expanded to include a full range of flow meter devices in order to help customers get the best out of their meters and to ensure that the meters are performing to their most efficient levels within customer applications.

Ergonomic Pipettes for Precision Liquid Handling


IKA PETTE unites everything lab technicians can expect for reliable metering in a single instrument. All models are fully autoclavable and can be easily sterilised. This ensures accuracy, precision and safety when metering. The large mechanical volume display is also easy to read as you perform the metering. The lightweight pipettes are particularly pleasant to hold thanks to three interchangeable ergonomic grips. The geometry of the receptacle is designed so that it is suitable for all commercially- available tips.


IKA PETTE fix and vario are also shock- resistant, UV and chemical resistant. Calibration and maintenance is user-friendly and can be done yourself or with the help of IKA Service.

With the MVP 030-3 C DC Pfeiffer Vacuum introduces a new corrosive gas version of the diaphragm pump. This version features a gas ballast valve and excellent chemical and condensate compatibility. The special choice of materials ensures significantly increased robustness in a wide range of processes.


The diaphragm pumps not only do their job reliably, but also quietly and with low vibration. The noise level is below 45 dB(A). Due to their compact design and low weight, they fit very easily into small analytical systems, mass spectrometers and turbo pumping stations. As backing pumps, they perfectly complement the turbopumps from Pfeiffer Vacuum’s HiPace range. Due to the reciprocal controllability, intelligent functionalities like boost mode and stand-by mode can be parameterised resulting in shorter pump down times, less power consumption and reduced wear. The diaphragm pump and turbopump can be controlled via a single Pfeiffer Vacuum control unit and supplied with power via a single common cable.


The efficient, brushless DC drive system allows the speed to be adapted to the requirements of the specific application. In automatic boost mode, the pump starts at a higher speed. The speed is reduced as soon as a certain vacuum is reached or a specified time interval has elapsed. In addition, this range of diaphragm pumps achieves excellent energy efficiency due to the standby mode and intermittent operation option in combination with turbopumps. The 24 V DC power supply means that the electrical design and associated safety measures are less complex, which further reduces costs.


The three-stage MVP 030-3 C DC is equipped with a manual gas ballast valve. The accumulation of condensate in the diaphragm pump can be prevented by opening the gas ballast valve. This ensures greater process reliability and a longer service life.


An added bonus is that maintenance of the diaphragm pump is very straightforward. Both the diaphragm and the valves can be replaced quickly and easily, making time-consuming servicing a thing of the past.
