Glass probes

While the PEM disk is in a beaker, there may be a tendency for the film to curl and lift on the steam bubbles, rising to the surface. It should be kept submerged so the top side doesn t get exposed to air. Use a clean inert polyethylene plastic or glass probe to keep it down in the dipping solution.

Figure 3. Neurophysiological preparation of Trichoplusia ni. Head, thorax and gut are removed. Tungsten electrodes were placed into the hemocoel along side abdominal ganglion VIII (at Rl), the ventral nerve cord (at R2) and the abdominal wall (ground, Rj). Injections of alkaline-dissolved BTI -endotoxin, methamidophos and phospholipase-A2 were into the second pair of abdominal prolegs (Ch). Mechanical sensory stimulation with a glass probe was at the anal proleg (S). Activity in the ventral nerve cord was monitored through 24 h post-treatment (38-40) (see Figure 4).

If uncertainties of 0.01°C or less, and/or if very small, fast-response thermometers are required, then thermistors must be used. Of course, they may be used also for less accurate work. Some bead-in-glass probe-type thermistors are stable and reproducible (Sappof, 1980), over a 1-year period, to the equivalent of 0.001°C, when used at temperatures below 100°C. Their response time can be as short as a few milliseconds.

Rudewicz and Manson have reported a method for the determination of additives in polypropylene without prior separation by solvent extraction or precipitation techniques, (Method 100) ". The additives are vaporized from polypropylene samples in a heatable glass probe under chemical ionization conditions using a 1.1% ammonia in methane reagent gas mixture. The dominant ion in this mixture, NH4 + is a low energy reagent ion that reacts with the additives to give very simple spectra of (M + H) or (M +... 

A small pellet of the sample is placed in the heatable glass probe and spectra produced evenly using the computer and data system. The identity and concentration of antioxidants present in the polymer is obtained from the profiles for the additives being determined.
