Measure Common Ions and O2 in Culture Plates
Recent developments in sensor technology has enabled Lazar
Research Laboratories, Inc. to miniaturize its line of ion and
pO2 probes so that they can now be used to measure very small
lab samples including microtiter plates, serum cups, HPLC
sample vials, and NMR tubes. Ion electrodes are available for
measuring common ions such as sodium, potassium, chloride, and
Probes for measuring less common ions such as bromide, iodide,
cyanide, sulfide, and thiocyanate are also available as well
as a special system for micro oxygen measurements.
Typical sensor diameter is less than 1mm for the ion probes
and less than 2mm for the dissolved oxygen probe. The ability
to measure small samples makes these probes especially useful
for biomedical research and biotechnology applications.
Other important features of these microprobes include
virtually unbreakable Teflon bodies, fast stable response
times which are typically less than 30 seconds, and low
detection limits enabling the researcher to detect ion levels
to below 1 part per million and oxygen levels below 100 parts
The probes can be used in various media including serum,
plasma, urine, whole blood, and various plant and animal
tissue samples. The pO2 probe can also be used in various
respiration studies. The ion probes require an immersion depth
of only 0.1mm for accurate readings while the pO2 requires an
immersion depth of 1 to 2mm.
All micro probes are available with the U.S. standard, B.N.C.,
and Radiometer connectors to be used with all common
pH/millivolt meters. Temperature range for the micro probes is
5 C to 70 C.
