UV-Vis spectroscopy is widely used for verification of the purity of different types of olive oil samples. Olive oil is rich in monounsaturated fatty acids, which are essentially all long chain fatty acids. Various scientific works have shown that these fatty acids help in lowering cholesterol levels along with lowering heart diseases. The oxidation is […]
A comprehensive quality assurance covering the entire production process is a must in any industrial sector. Density measurements are frequently used for this purpose, especially in the pharmaceutical, chemical, petrochemical as well as the food and beverage industry. They allow the manufacturer to analyse raw materials, semi-finished and finished products as well as the manufacturing […]
Capp pipette cone filters are small pieces of Polyethylene (PE), designed to be inserted in the tip cone of a 1 and 5mL ecopipette and 5 or 10mL CappBravo pipette. They are available in bags of 25 or 50 pcs. Their hydrophobic structure with high density creates a perfect barrier for corrosive vapors and other contaminants. […]
Maximum efficiency and increased time savings through automation options With our refractometers DR6000-TF with integrated Peltier element, the entire measuring process can be carried out semi-automatically or fully automatically and without manual intervention, from sample supply through cleaning to drying. Due to automation, measurements can be user-independent and overnight or at the weekend. This increases […]
Are you in control of your PCR protocol?, or does it work one day but not the other? Being in control of your PCR protocol means obtaining results you can rely on. Results, that are reproducible and accurate. Establishing your PCR protocol – 5 crucial variables When preparing your PCR protocol, you usually focus on […]
Discovery of spectral polarimetry? A polarimeter is a device for determining the polarisation direction of the light or the rotation of an optically active substance. The physicist Francois Jean Dominique Arago made a discovery on quartz, which was very important for polarimetry. Arago cut a quartz crystal perpendicular to the crystal axis and saw the […]
Micropipettes are high precision instruments suitable for liquid transfers of volumes as small as 0.1µl, pipettes are quite vulnerable to improper pipette storage. Horizontal pipette storage on the bench may cause the piston lubricant to cumulate on one side, or even drop of the piston, resulting in a heavy piston movement. Laying your pipette down […]
