KIN-TEK Trace Source™ permeation tubes use a mixture of reagent-grade nitric and sulfuric acids as the analyte source. The sulfuric acid binds the water, reducing water emission to negligible levels. Emission of the sulfuric acid is extremely low compared to that of nitric acid, so the emission is primarily nitric acid. Formation of nitrogen oxides in the vapor is minimized by dynamically blending the emission to form trace concentration mixtures that are then used immediately. Tubes are available for concentrations from low parts per billion to about 10 ppm in 1-L/min dilution flow. KIN-TEK Laboratories Inc. (La Marque, Texas).

Theseflush-valve assemblies are built to ensure exact flow rate while resisting water degradation and component swell. Molded of a custom thermoplastic elastomer and acetal formulation, the valve assemblies have the physical properties intended to meet demanding pressure flex requirements. The assembly diaphragm incorporates the Aqua Advantage™ design with tight tolerance and flash-free bleed holes. The design enables the diaphragm seal to unseat properly for the flush operation and return to its seated position, sealing off water flow once the preset flow has occurred.

The OMEGA® iSD-TC series provides Web-based temperature monitoring in computer server rooms, clean rooms, laboratories, warehouses, or any remote facilities. The device enables users to view and record temperature on two independent thermocouple channels over an Ethernet network or an Internet connection with just a Web browser — no special software needed. The device also triggers an alarm if the AC power fails and will continue to collect data for 2 days powered by a standard 9-V alkaline battery (included). Omega Engineering Inc. (Stamford, Conn.).
The T&B® Fittings Form 7 and Form 8 Conduit Outlet Bodies feature an interior BlueKote® finish, which creates a smooth surface that facilitates wire pulling and prevents wire damage while providing an additional layer of corrosion protection. The finish is in addition to three layers of interior and exterior protective coatings, including two layers of epoxy. The multiple layers of protection exceed industry standards for conduit outlet bodies in a 500-hour, 5% salt-fog chamber test. Form 7 is available with preassembled covers and gaskets. Thomas & BettsCorp. (Memphis, Tenn.).
The DIN-rail-mounted Varitector VSPC surge-protection devices safeguard signal circuits in control and instrumentation applications. The surge-protection line includes more than 60 models with a robust range of pluggable, replaceable, single- and multiple-channel modular surge-protection devices. Meeting Underwriters Laboratories 497B requirements, the devices provide a combination of wire-to-ground and wire-to-wire protection. The separate bases accommodate field connections and make a ground path from the surge protection devices via the grounded DIN-rail. Weidmuller (Richmond, Va.).
The SFT Phase Monitor II is an analytical tool for determining the solubility of various compounds and mixtures of compounds in subcritical and supercritical fluids. It provides direct visual observation of materials under conditions that the researcher can control. Experiments may be performed in liquid or supercritical carbon dioxide or other compressed gases. The effect of co-solvents on the solubility of compounds of interest in supercritical carbon dioxide can be investigated with this instrument. It enables the user to view the dissolution, precipitation, and crystallization of compounds over a wide range of pressures and temperatures. Experiments can be conducted from a few hundred to 10,000 lb/in.2 and from ambient temperature to 150°C. Supercritical Fluid Technologies Inc. (Newark, Del.).
