New line of reagent vials for chemical oxygen demand
Here's a new line of reagent vials for performing chemical oxygen demand (COD) analysis.
New since January 2002, in addition to its 30-count packs, the company offers 150-count packs for the 0-150 and 0-1,500 ppm ranges and 100-count packs for the 0-15,000 range vials (both methods).
These COD reagent vials promise excellent results and can help decrease operating costs without modifying existing equipment or procedures (micro-COD reactor digestion method).
Contained in environment friendly biodegradable packages, the vials feature optical-quality glass for accuracy, Teflon-lined screw caps for inertness, and the standard 16 mm diameter vial size for compatibility with most reactors and digesters.
And, the firm offers COD products for the EPA approved method and a mercury-free method.

Improved equipment for gasoline oxygenate analysis
Improvements in this firm's equipment and procedure meet or exceed the American Society for Testing and Materials D4815 method of oxygenate in gasoline analysis.
The improvements help make backflush time more reproducible and easier to determine, the firm notes.
Nine commercial trap columns were tested. Three were unusable because of blockage; optimum backflush times on the other six ranged from 0.10 min to 0.34 min.
New trap columns were made with a different design and better temperature control, which reduced the range to 0.28-0.30 min.
The 6890 Series gas chromatograph analyzers using the new trap columns exceeded all ASTM specifications for this method, the firm points out.

Printer program handles seismic data
Newly released EasyCopy 7.0 offers a program suite of image communication tools for screen capture, conversion, and printing.
It handles seismic data for viewing and converting as easily as it can print or send an image, the company points out.
The program comes with tools that let the system administrator create and manage print queues throughout the network.
You can now install a printer in EasyCopy and connect it to a print server without the need for a local print queue. You can also update installable options from the printer setup dialog, which means that you no longer have to reinstall the printer if its configuration has been upgraded.
This latest version includes new enhanced drivers for HP DeskJet printers.
The print quality you can achieve from a DeskJet printer has been considerably improved with the new drivers, and the quality is optimized for your particular choice of media.
You will notice the improvement if you print photographs or rendered models, the company says.

Rope designed for marine operations
Ultrex single braid, incorporates high technology fibers into high performance rope.
Ultrex, which is made of Dyneema SK75 fiber, combines light weight, high strength, low stretch, and buoyancy, and is designed for marine applications traditionally reserved for steel cable or haw sers.
The rope also incorporates Maxijacker coating. Ultrex is designed to withstand difficult conditions without fraying or breaking.
Ultrex is available in diameters of 3/8-2 in., with average breaking strengths ranging from 20,000 lb to 390,000 lb.

New combustible gas monitor
The new Model 2001 combustible gas monitor is a compact, solid-state, fixed-installation, single alarm version. It performs continuous area monitoring of combustible gas in the 500-10,000 ppm methane range.
Output features include LED indication of alarm, audible buzzer output, or electronic output signal to an alarm panel.
The monitor comes standard with a normally operating open relay, but the user can also select a fail-safe normally operating closed relay.
A solid-state semiconductor-type sensor and associated electronic circuitry help ensure trouble-free, long-term operation.
Except for periodic calibration to verify alarm setting, no attention is required after installation.
