Supplier: PerkinElmer
Description: These electrodeless discharge lamps are preferred for certain volatile elements. They offer better precision and lower detection limits for analyses that are 'noisy' due to weak hollow cathode emission. PerkinElmer system 2 EDLs consist of the element or a salt of the element sealed in a quartz bulb containing an inert gas atmosphere. When an RF field of sufficient power is applied, the inert gas is ionised and the coupled energy vaporizes the element and excites the atoms inside the bulb, resulting in the emission of the characteristic spectrum.

Supplier: VACUUBRAND
Description: These chemistry pumping units use chemical resistant solenoid valves to maintain process control. Once the first boiling point is detected by the controller, it maintains the pressure at this level. Pumping units can be configured to run one or two independent processes at the same time.

Catalog Number: (92446-5ML)
Supplier: Merck
Description: Sodium methoxide may be used as a derivatisation reagent to enhance the sensitivity of detection for the subsequent determination of organonitrogen herbicides and fungicide analytes in food samples, and bound fatty acids from acylglycerols, alkylacylglycerols, galactosyldiacylglycerols, glycerophospholipids, and sterol esters by gas chromatography (GC) based techniques.

Catalog Number: (BOSSBS-13248R-A750)
Supplier: Bioss
Description: Heterotrimeric G proteins function to relay information from cell surface receptors to intracellular effectors (1). Each of a very broad range of receptors specifically detects an extracellular stimulus (a photon, pheromone, odorant, hormone or neurotransmitter) while the effectors (i.e., adenylyl cyclase), which act to generate one or more intracellular messengers, are less numerous. In mammals, G protein alpha, Beta and Gamma polypeptides are encoded by at least 16, 4 and 7 genes, respectively (2-5). Most interest in G proteins has been focused on their a subunits, since these proteins bind and hydrolyze GTP and most obviously regulate the activity of the best studied effectors. Four distinct classes of G alpha subunits have been identified; these include Gs, Gi, Gq and Ga 12/13 (3,4). The Gi class comprises all the known a subunits that are susceptible to pertussis toxin modifications, including Ga i-1, Ga i-2, Ga i-3, Ga o, Ga t1, Ga t2, Ga z and Ga gust (4). Of these, the three Ga i subtypes function to open atrial potassium channels (6). Ga 16 is a member of the Gq subfamily and is expressed specifically in hematopoietic cells (7).

Supplier: SIGMA ALDRICH MICROSCOPY
Description: It may be used to prepare porphyrin based matrices for the detection of water soluble vitamins by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry. It may be used to prepare 5,10,15,20-tetrakis (4-polyethyleneoxy)phenyl)) porphyrin. Nanoporous silica inserted with 2H-OHTPP imparts gas sensitivity, and it could be useful to detect NO2 by surface plasmon resonance.

Catalog Number: (CHRASP372)
Supplier: CHROMAGAR
Description: CHROMagar™ StrepA is a selective chromogenic culture medium intended for use in the qualitative direct detection, differentiation and presumptive identification of Streptococcus pyogenes -group A Streptococcus (GAS) to aid in the diagnosis of GAS throat infections. The test is performed with throat swabs. Results can be interpreted after 18-24 h of incubation at 35 - 37 °C under CO² atmosphere.

Supplier: Merck
Description: Merck offers a broad variety of withdrawal systems that are tailor-made for barrels and drums. They are designed to ensure safe, easy and efficient solvent withdrawal-even of residual quantities-while meeting all relevant safety regulations.
The integrated solvent supply systems directly connect the solvent to the instrument or product line where it is needed. We provide systems for manual pressure build-up as well as inert gas pressurising, supplemented by a comprehensive selection of reducers, adapters and couplings that allow easy interconnection of all components. This way the user can precisely manage his solvent flow and thus optimizes the processes-and at the same time minimizes risks for the employees and the environment.
Catalog Number: (300-0280)
Supplier: Saint Gobain Life Sciences
Description: Made from 2 mil thick PVF fluoropolymer film. When the chemical inertness of FEP is not required, Chemware® heat-sealed, PVF gas sampling bags are the ideal choice. These reusable bags are the perfect economical alternative for analysis of non-corrosive gases. Can be used when the user is dealing with carbon monoxide, sulphur dioxide, hydrogen sulfide, radon and mercaptans. Ideal for extracting air samples from smoke stack exhaust systems in fuel gas sampling applications.
