Micro pH Electrode Measures pH of Single Drop
A micro combination pH electrode has been introduced by Lazar
Laboratories, Inc. that will measure samples as small as 10
microliters (about 1/4 the size of an average drop) in biological
media such as cell culture, NMR tubes, gels, and biohazardous media.
The PHR-146 micro pH electrode fills the need for an accurate yet
unbreakable pH electrode for routine analysis in biological media.
The sensor is totally non-glass and is resistant to degradation due
to protein binding. A long flexible fluoropolymer electrode stem
allows the user to conduct biological assays in containers such as
microtiter plates, culture tubes, cuvettes, micro test tubes, serum
cups and NMR tubes. Due to the extreme flexibility of the stem, the
probe can also be inserted into curved glass vessels.
The probe has a much lower imput impedance than conventional glass
electrodes, giving the user the advantages of high stability, rapid
response time, and high signal to noise ratio. It is useable with any
laboratory pH meter. The pH sensor has a diameter of 1mm, and a
combined diameter of 1.7mm, including the reference element. The pH
sensor tip is also applicable for surface measurements on filter paper
and eletrophoretic gels.
The micro combination pH probe is compatible with all major brand
pH meters including Orion(R), Beckman(R), Corning(R), Fisher(R),
