A new range of laser-etched alphanumeric coded sample storage tubes (0.5 mL, 0.75 mL, 1.1 mL, and 1.4 mL) is now available. The new tubes have a flat polypropylene bottom on which the alphanumeric code is encrypted with a laser. Uniquely manufactured from a single component—the laser-encrypted alphanumeric codes cannot fade or peel off even when subjected to repeated handling, exposure to different solvents, or multiple freeze-thaw cycles. Because code clarity will remain unchanged throughout their lifetime, the laser etched alphanumeric coded tubes offer the security of unmatched sample traceability. Manufactured from high-quality polypropylene in a fully automated class-7 cleanroom environment ensures the laser-etched alphanumeric tubes exhibit absolute product consistency, near-zero contaminants, and compliance with U.S. and European Pharmacopoeia tests. The laser-etched alphanumeric tubes resist many organic solvents (DMSO, methanol, dichloromethane), may be autoclaved clean, and can be repeatedly freeze-thawed without loss of product performance.


Highly accurate and exceptionally easy-to-use, the Coliform Bath is specially designed for fecal coliform and E. coli testing. It features an ambient +10°to 135°temperature range, ±°temperature stability, a 28 L reservoir, and is equipped with the company's economical MX temperature controller. Suitable for APHA, AWWA, WEF, and EPA fecal coliform determinations as well as other standard coliform and E. coli tests, the Coliform Bath is equipped with a hinged see-through gable cover, single-speed pump, user-adjustable temperature alarms, calibration capability, and chemical resistant top plate. Its highly intuitive MX controller makes temperature and operational changes particularly simple and straightforward. A large backlit readout displays both actual and set point temperatures and temperature units, high- and low-temperature alarm levels, and calibration which are all user adjustable.


Developed to meet the growing need for in-situ transfection of hard-to-transfect adherent cell types, the new Cellaxess ACE Adherent Cell Electroporation System enables transfection and delivery of nongenetic material in any adherent cell type at any developmental stage. The platform enables in situ primary and iPSC-derived cell types directly in 96- and 384-well microplates and cell culture dishes at any cellular developmental stage with excellent viability and completely retained cellular morphology. Cellaxess ACE is available as a complete system, but can also be integrated with third-party pulse generators. Applications for the Cellaxess ACE include transfection of various types of neuronal cells such as hippocampal and cortical neurons, dorsal root and superior cervical ganglia from rat or mouse, and human iPSC-derived dopaminergic neurons. Protocols are available for a wide range of neuronal cells as well as other adherent cell types.


The Cedex Bio HT Analyzer is designed for the highly reliable determination of metabolites and substrates in mammalian and microbial cell fermentation. The Cedex Bio HT System offers very precise analytics, a broad test portfolio allowing flexible adaption of additional test menus, and convenience with the highly automated platform which processes up to 120 tests per hour. Designed for high throughput applications such as in-process development, the system produces data that can be directly compared with data from Cedex Bio and Cedex Bio HT Analyzers located worldwide. By minimizing hands-on time, the Cedex Bio HT Analyzer demonstrates greater precision, sensitivity, and linearity than instruments that use membrane-based technology. It includes three different measuring methods enabling the analysis of IgG (immunoglobulin G), LDH (lactate dehydrogenase), and various substrates and metabolites including glutamate, glutamine, sodium, potassium, glucose, lactate, and ammonia.


A range of Scientific Urine Collection Kits offers the necessary components for safe and hygienic specimen collection and handling, with the added bonus of a primary collection tube. The kits are both CE and IVD approved and are available either plain or with boric acid and are supplied in bags of 50 to facilitate customer distribution. These comprehensive kits, which include a simple instruction leaflet, consist of a polypropylene test tube complete with cap and a flexible sample cup for easy transfer to the test tube. The test tube is labeled with all the details required for sample identification and may be placed directly into an analyser. Designed to not only assist patients in convenient and hygienic urine collection, the kits also bring benefits to the laboratory. For example, improved base line results are achieved for the microbiologist as the primary tube provides a faster and more reliable result, saving time and money for all parties.
