Laboratory Products 25 Oxidation Stability of Flavoured Spirits using PEG as Carrier Material
Distilled alcohol is otherwise known as ‘hard liquor’ or ‘spirits’. Classic spirits are often mixed with different flavours in order to reach new customers - thereby expanding a brand’s market share. One such spirit, gin, is distilled from juniper berries and contains no additives. However, raspberry and blackberry flavoured gin is also available. Such flavour additives often contain antioxidants and can affect the shelf life of the product. Using the Rancimat method with polyethylene glycol (PEG) as carrier material, the oxidation stability of flavoured and unflavoured gin can be determined quickly and reliably. The sample is analysed without any preparation, and the induction time can be related directly to the oxidation stability of the sample.
This Application Note from Metrohm demonstrates the feasibility of the Rancimat method. Reproducible and accurate determination of the oxidation stability of flavoured spirits is possible with the 892 Professional Rancimat.

IR Hotplate/Stirrer Saves Time and Energy
The latest infrared heating technology has been used in the design of the WH260-NH hotplate-stirrer from Wiggens. Thanks to this radiation heating technology, the Wiggens WH260-NH can be used for rapid heating up of various shaped vessels, including round-bottom flasks, and the solution inside can be heated up to a maximum of 450°C in a very short time.
The new Wiggens hotplate stirrer enjoys the benefits of a Schott glass ceramic surface with exceptional chemical resistance, a high surface quality, and a resistance to temperature shocks of more than 700°C, providing the users with optimal solution compared to conventional heating surface materials. The poreless smooth surface enables even the most stubborn dirt to be easily cleaned. The high infrared permeability ensures that the heating energy is transferred quickly and with very limited loss, therefore, it heats liquids fast and saves time and energy. Intelligent Cascade Control enables self-optimising to reach perfect temperature stability. If the Pt-100 sensor is connected, temperature-controlled work with stability of +/- 2°C can be reached in most applications.
In addition to rapid heating capability and superior temperature control, the WH260-NH also offers well controlled gentle to intense mixing of liquids, and is also suitable for large volume viscous media.
The stirring and heating can be controlled separately by convenient turning knobs. All functions can be viewed and monitored on a bright touch screen, including most frequently used parameters, such as, working temperature, stirring speed, working time, and safety temperature. Memory function for stirring speed and temperature setting makes it convenient to start the experiments with fixed conditions. A residual-heat display protects the users from burning their hands.
With the aforementioned benefits, and many other features, the Wiggens hotplate stirrer is the optimal solution for heating and mixing of liquids in labs, for gentle to intense applications.

ADVERTORIAL Quick and Easy Blood Sample Collection
CapilliSafe Pastettes from Alpha Laboratories are the ideal solution to replace glass capillary tubes for blood sample collection. Each pipette fills easily to a pre-set volume using capillary action. The flexible polyethylene CapilliSafe Pastettes are safer and less expensive than glass tubes. They draw and dispense blood quickly without the need for anti-coagulant coatings. No additional bulbs, dispensers or other mechanical devices are necessary.
To use CapilliSafe simply prick the finger with a lancet or similar implement and allow a drop of blood to form. Hold the pipette horizontally touch the tip to the blood droplet. There is no need to squeeze the bulb as draw is automatic. Capillary action will automatically draw the sample to the fill line and then stop. To expel the sample, hold the CapilliSafe Pastette vertically, align the tip with the sample target and squeeze the bulb.
These single-use pipettes collect and dispense a specific volume (25μl or 50µl) of blood at ±15% whilst minimising the occurrence of air bubbles in the collection tube. An air vent is strategically positioned on the sidewall of the tube. This allows air to vent automatically, while controlling sample volume.
Perfect for use in diagnostics kits CapilliSafe Pastettes are not currently CE marked but are perfect for use in point of care diagnostic kits, where the whole kit will be CE marked.
