Laboratory Products 53 Extensive Offering for Cryogenic Sample Homogenisation
Reproducible grinding and homogenising of solid sample materials is an important step of sample preparation. However, not all materials can be successfully processed at room temperature. Some samples, for example, must not get too warm while others are very elastic and just deform when being submitted to size reduction.
The ideal solution for thoroughly homogenising these types of samples is cryogenic grinding which involves the use of dry ice or liquid nitrogen as grinding aid. Their cooling effect makes the sample brittle and lets it break more easily; moreover, negative effects of the frictional heat generated by the grinding process are eliminated so that, for example, volatile sample components, which are frequently the object of analysis, are preserved.
Retsch offers a wide range of laboratory mills suitable for cryogenic grinding of a large variety of materials. The CryoMill was developed specifi cally for this application and features an integrated cooling system. The continuous cooling of grinding jar and sample with liquid nitrogen ensures a highly effective grinding process. The operation is very safe for the user as he doesn’t come into contact with LN2 at any point.
Further Retsch mills which can be used for cryogenic grinding thanks to appropriate accessories include the Ultra Centrifugal Mill ZM 200, Mixer Mill MM 400, Cutting Mill SM 300, Knife Mill GM 300 and Mortar Grinder RM 200. Retsch has produced a number of application videos for cryogenic grinding which can be watched on the website

40824pr@reply-direct.com OEM Portfolio Expanded with Pulssar Technologies Precision Pumps
Tecan has extended its OEM product portfolio through the acquisition of the PBC, PSR and PBR piston pumps from Pulssar Technologies. These long life, high precision products are ideal for the automation of dispensing and pipetting tasks in life sciences instrumentation, and perfectly complement the Tecan Cavro®
range of syringe pumps and pipetting solutions. This gives instrument designers an even broader choice of liquid handling technologies, as well as an array of robotic and valve options, backed by Tecan’s application expertise and global support infrastructure.
Joe Rotter, Vice President of Global Marketing for Components, said: “Pulssar’s high throughput precision pumps enhance our existing product portfolio, meeting the application-specifi c needs of different customer segments. Pulssar’s reputation for low volume accuracy and precision is a perfect fi t for the high quality liquid handling and robotic platforms and components we offer our OEM partners.”
Khaled Abousaleh, founder of Pulssar Technologies, added: “We are very excited that Pulssar has become part of Tecan Partnering through this acquisition. The confi gurability and unique features of our piston pumps, combined with Tecan’s advanced pump technologies and robotic solutions, offer real synergistic value for new and existing customers.”
