New Tubes and Plates Maximise Sample Recovery
Eppendorf launches new Protein LoBind Deepwell Plate 96/2000 µl and extends the Eppendorf LoBind product portfolio to 96-well high volume plate formats. The unique format flexibility enables customers to easily up-scale their experiments and achieve the same high quality results.
Storing or incubating biological samples for 24 hours in standard reaction vessels can result in the loss of more than 90% of the sample, due to adsorption to the plastic surface. Designed to maximise the recovery of valuable biomolecules, Eppendorf’s innovative LoBind® consumables are manufactured using specially developed production technologies and selected ultrapure polypropylene, for significantly reduced sample-to-surface binding. The absence of any surface coating, such as siliconisation, slip agents, biocides or plasticisers, prevents sample interference, while the material’s high chemical and thermal resistance ensures safety in all sample preparation protocols.
DNA LoBind Tubes and Plates are available for DNA or RNA applications in forensic analysis, microarrays, next generation sequencing, gene cloning and molecular biology. Protein LoBind Tubes and Plates are ideal for protein research, mass spectrometry, protein array sample preparation, and storage of peptide, antibody or virus samples. Both materials are offered as single tube formats ranging from 0.5ml to 2ml volumes and 96-well or 384-well micro- and deepwell plates with RecoverMax®
well shape. Circle no. 70 Circle no. 71 Total Fat Determination in Food and Feed Samples
Velp Scientifica has released the new Hydrolysis Unit HU 6 able to perform acid and basic hydrolysis of food and feed samples, prior to solvent extraction using the SER148. The HU 6 performs hydrolysis in complete safety and handles six samples at a same time in order to maximise productivity. The HU6 works in combination with the SER148 according to Official Procedures, providing highly accurate and precise results for fat content determination.
Circle no. 72 New FTIR Methodology for Measuring Contamination in Diesel Fuel
A2 Technologies PAL and iPAL FTIR analysers are gaining rapid acceptance for measuring biodiesel (%FAME) in diesel fuel for applications where low level contamination of diesel fuel by FAME is problematic. Diesel fuel containing up to 5% biodiesel meets the ASTM D975 standard, which does not require disclosure of the biodiesel level, and this can be a significant issue for certain diesel fuel users. A2 Technologies (A2) has developed an enhanced method for determining contamination levels of FAME in diesel. This method combines the more sensitive transmission IR sampling interface specified in EN 14078 with the universal algorithm and sample set specified in ASTM D7371 to produce the most sensitive and accurate method available. This enables the PAL systems to quickly and accurately predict the percentage of biodiesel in diesel fuel in the range from 0.025% to 20%. In round robin testing, the accuracy of this method has been found to be superior to the other methods, especially for measuring low levels of biodiesel.
The PAL systems use A2's patented TumblIR IR transmission technology to provide the 100 micron pathlength specified in the EN 14078 method. The TumblIR sampling system eliminates the difficulties associated with using traditional IR transmission cells and is as easy to use as the ATR type device specified in the ASTM method. Measurement of % FAME is as easy as placing a drop of diesel fuel on the TumblIR lower window, rotating the top window into place and then initiating the measurement. The two windows, when placed in the measurement position, create a 100 micron pathlength as specified in the EN 14078 method. Clean-up is as simple as rotating the windows apart, and then cleaning the two windows with a simple wipe.
