Calitech Zero Oxygen Standard In Single-Use Pouches
|
A solution of ascorbate and sulfite formulated with anti-microbial. This
solution provides a zero standard for proper and accurate calibration.
Calibration with Calitech Zero-Oxygen Standard eliminates the errors from
electrical (disconnect) zero calibration which arise from internal offsets in the
electrode. Because the solution is fresh each time, the problems with homemade
solution stability are eliminated.

Calitech Tonometer
|
Aurical Company provides a novel Tonometer, unique in that it is
completely transparent and has no moving parts. The Tonometer permits easy
and controlled saturation of fresh water or salt water with gasses, including air.
The electric pump causes the ambient air to bubble up through the water in the
vessel. The gas diffusion plate in the bottom of the vessel breaks up the flow
into bubbles of the correct size to assure proper equilibration. As an additional
feature, other gas mixtures may be substituted for ambient air. Selecting different
concentrations of gas in the mixture allow preparation known standards of
varying values.

Calitech Oxygen Probe Conditioner
|
The Oxygen Probe Conditioner is an electrical device designed to
bring polarographic oxygen probes to their true zero state. The Oxygen Probe
Conditioner applies the required bias voltage to the connected probe. While
connected, the probe is immersed in Calitech Zero Oxygen Standard. Storing
probes connected and immersed this way assure instantaneous readiness for
testing. The traditional conditioning period necessary for use is eliminated.
The Oxygen Probe Conditioner is battery-powered. Cat. No. 2-530, is used
in bench-top, field operations, and at elevated temperature (150°C) and
pressure (30 psi) when autoclaving is necessary
