Pipettes are an important tool in any research laboratory, so are worth the added care to ensure they continue to work smoothly.
Why regular calibration is essential
Even pipettes which are carefully handled, appropriately stored and regularly cleaned need to be regularly calibrated – every six to 12 months, depending on laboratory workfl ow requirements – by the manufacturer or a specialised company. Keeping up-to-date records of past calibrations helps to ensure the next date won’t be missed. Some electronic pipettes and pipette software packages even allow calibration reminders to be set, or the service history to be recorded, to help keep track.
Regular calibration will ensure that pipettes provide ongoing precision and accuracy, as well as allow early detection of potential problems. Issues can therefore be fi xed before more costly repairs - or replacement - becomes inevitable. These simple guidelines can guarantee prime pipette performance and the provision of reliable results for years to come.
Conclusions
This article explains simple steps that all laboratory staff can implement today to keep their pipettes delivering continuous and prolonged accuracy, offering reliable results for years to come. The best way to guarantee optimal care is to ensure you have enough stands to store all your pipettes, and to set up a regular schedule for cleaning, maintenance and calibration.
If you still have unanswered questions about the handling, cleaning or calibration of your pipettes, don’t hesitate to contact the experts at Integra Biosciences.

New Interface Software for Improved Flowmeter Functionality Titan Enterprises launches their advanced interface software for the Atrato®
ultrasonic fl owmeters.
The Atrato line of patented ultrasonic inline fl owmeters consists of four models operating over a fl ow range of 2ml per minute up to 20 litres per minute. The USB connection gives the Atrato computer interface capability, enabling the user to directly monitor the fl owrate being measured and alter the operating parameters using a PC.
Titan’s development of the Atrato’s new interface software features four key functionality improvements: the ability to connect, confi gure and operate multiple Atrato fl owmeters on a computer simultaneously whilst minimising CPU usage; additional capability to run simple local and remote-control batching operations using an inbuilt relay; remote start/restart capability for long shut-down periods; the ability to increase signal gain via the software for liquids with poor acoustic properties.
The Atrato interface software enables the user to log the fl ow data directly via the USB. This data-logging capability gives a continuous picture of the fl ow characteristics of the system being monitored, such as fl ow, alarms, relay and pulse. The upgrade integrates developments in both the Atrato’s internal software and the PC interface software, providing a combination of increased versatility and advanced operational features.
Atrato fl owmeters are industry proven with good chemical compatibility, ideal for laboratory applications, cooling equipment, pharmaceutical, chemical and petrochemical processes, water and OEM high precision applications. With no moving parts, mechanical wear is virtually eliminated, critical for long-life and repeatability and reducing the requirement for recalibration.
Taking advantage of proprietary embedded signal processing software developed by Titan Enterprises, both viscous and non-viscous liquids can be routinely measured precisely. The low fl ows that the Atrato fl owmeter is capable of measuring vary from laminar to turbulent and are highly immune from viscosity. With unparalleled turndown, repeatability, and linearity, the Atrato can monitor fl ow over a range of 250:1.
The Atrato interface software is supplied with the fl ow meters and can also be downloaded from Titan’s website. Although the upgraded software is ‘backward compatible’ and will work with older Atrato models, not all the new features will be accessible.

ilmt.co/PL/2p4J Flow Chemistry System for High Yield Heterogeneous Catalysis
The FlowLab Column from Uniqsis is a continuous fl ow chemistry system developed as an affordable high-performance replacement for conventional stirred batch reactors often used for heterogeneously catalysed liquid phase reactions.
Designed to provide highly effi cient mixing and excellent control over reaction parameters, the FlowLab Column provides intimate contact between a large excess of catalyst and a small quantity of reagent at any point in time resulting in increased reaction rates and higher yields. The FlowLab Column is based upon a HotCoil heated reactor module fi tted with a HotColumn adapter to enable operation up to +260°C (300°C as an option).
As standard the FlowLab Column can either accommodate six 316 stainless steel columns in individual insulated holders, each capable of operation up to 100 bar. Or, six glass columns with adjustable end pieces and plunger to vary the catalyst bed volume. These columns operate up to bar and 150C This confi guration facilitates easy scale-up whereby the required number of identical columns are simply connected in series.
Each FlowLab Column system includes pressure regulating non-return valves before the column reactor to prevent the possibility of back fl ow into the pumps at any time.
FlowLab software provides control of the system via a step-through interface that can be learnt in minutes and is highly intuitive to use. Programs can be designed and saved reactions run automatically, including priming and washing. The program is monitored on a real-time display showing temperatures and pressures. FlowLab software also automatically detects any modules that have been added to the system.
