Electrodeless discharge lamps

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.

Product Image-751-0075

Flashpoint testers, Setaflash 8

Catalog Number: (751-0075)
Supplier: STANHOPE SETA
Description: These testers are automated closed cups with ramp mode that allows the determination of a flash point. The dipping sequence occurs every 1 °C up to 100 °C (every 2 °C rise above 100 °C) until either a flash is detected or the end of test temperature is reached. The ignitor uses a new electrical hotwire (a gas flame option is available). The automatic flash detection system is tuned to ignore halo and other false flash effects enhancing repeatability.

Product Image-131-0042

Chemistry vacuum pumps and systems with valve control, dual application

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.

Image Unavailable-BOSSBS-13248R-A750

Anti-G protein alpha 16 Rabbit Polyclonal Antibody (Alexa Fluor® 750)

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).
