The Prevail range of water wettable C18 SPE columns does not require traditional preconditioning with an organic solvent. This eliminates organic preconditioning thereby reducing handling and disposal of hazardous organic solvents. It will also eliminate one step from typical SPE procedures with accompanying savings in time and, because it is a standard silica-based C18 sorbent, it can be substituted directly into methods or established protocols that call for C18 without the need for recalibration. It performs just as well as standard C18 sorbents with and without organic preconditioning, so it can be used for any C18 application and sample type.
Coeliac disease patients are characterised by a particular immunogenetic profile. DQ2 haplotype is present in up to 90% of coeliac patients, while non-DQ2 coeliac patients are mostly DQ8 haplotype.
The Primacs SN Protein Nitrogen Analyser from Skalar Analytical offers a solution to solid sample analysis for nitrogen. The unit features fast, accurate results, with ease of operation and low maintenance.
The Shindengen KS723 non-glass pH meter is a robust pocket sized meter based on ISFET semiconductor technology. The pH meter is well suited to both laboratory and field use as it does not use a glass electrode. It is also suitable for the food industry and applications where traditional glass electrodes are not suitable.
The Testo 505 Manometer is an electronic measurement cell designed for general purpose use. It measures and displays differential pressures up to ±130 hPa/mBar and has a magnetic back for hands-free ease of use.
The Process Analyzers 301-B automatic gas chromatograph is a PC-based GC designed for unattended, continuous monitoring of a wide range of chemicals in ambient air, stack, or processes. With a choice of detectors (thermal conductivity, flame ionisation, and photo-ionisation) the model 301-B offers auto calibration and multiple user-programmable alarms.
The TSK Surfcom 3000A is an integrated surface texture and contour measuring instrument. It offers realisation of 0.005 µm for resolution, and its dynamic range and resolution ratio is 2,400,000:1.
The WPA Cell Density Meter is a compact instrument that provides instant cell density readings at the touch of a button. The Biowave CO8000 is a low cost easy to use portable cell density meter with wavelength 600 nm, range -0.3 to 1.99 A, RS-232 output and a custom LCD. The Biowave CO8000 cell density meter is neat and compact, taking up less bench space than a spectrophotometer. Readily portable, it can be used anywhere needed, eliminating the safety hazard of carrying bacterial samples to and from a fixed instrument. It is no problem to use it within a laminar flow cabinet so that work with micro-organisms can be completed without leaving the sterile bench.
Heine Alpha+ ophthalmoscopes and retinoscopes are pocket-sized. The optical components of both instruments are mounted in metal frames for constant precision and long working life. Both instruments use compact Alpha+ handles for easy pocketability and both incorporate clips for user convenience.
The testo 177 series of data loggers consists of five different data loggers, measuring temperature (177-T1/2/3/4) and humidity (177-H1). The 177-T3 has two external NTC sensors with a contact closure, which can change the time interval between taking readings, while the 177-T4 provides four external thermocouples.
Omnifit's inert colour-coded connectors provide a simple, versatile system for connecting different types of laboratory tubing instantly, including PTFE, glass, silicone and stainless steel. Applications include sampling, stream splitting, mixing and fluid line interconnection.
Stem Cell Sciences Limited (SCS) has a novel assay for finding drugs that may provide therapy for people with Alzheimer's disease, or prevention of the disease.
Leybold's Divac L range of pumps are dual stage diaphragm vacuum pumps, fully teflon coated. The pump is suitable for the laboratory as it is insensitive to aggressive and corrosive media.
OptiCell Tissue Culture Plates provide a sterile, sealed cell culture environment between two optically clear gas-permeable growth surfaces in a standard microtiter plate-sized plastic frame with specially designed ports for access to the contents. OptiCell is the ideal environment for cell growth, microscopy, treatment, selection, separation, harvest, storage, and shipping. OptiCell can also be used for the production of cell products such as monoclonal antibodies and cytokines.
Panorama gene arrays provide a semi-quantitative platform for analysis of the expression of hundreds of genes in a single experiment.
