Fisherbrand™ accumet™ Glass Body Standard Size Combination Electrodes - Mercury-Free
For routine pH and titration measurements with small samples and small vessels, where separate half-cell electrodes may be impractical
Includes: Removable bulb protector
Description
For routine pH and titration measurements with small samples and small vessels, where separate half-cell electrodes may be impractical
- 0 to 14pH range
- Porous ceramic junction
- Twist-open/twist-close cap for easy filling
- Constant distance between FS-5 Universal Glass pH bulb and reference junction means high reproducibility
- Immersion depth, ∽4 in. (10.1cm)
- 30 in. long (76.2cm) leads, except 13-620-91, which has 60 in. long (152.4cm) lead
Choice of Ag/AgCl Single- or Double-Junction internal reference elements
- Single-junction models with Ag/AgCl reference are perfect for routine pH and titration measurements of aqueous solutions with small samples, small vessels
- Double-junction models with Ag/AgCl reference are useful in aqueous and nonaqueous solutions, and in applications requiring TRIS buffers
- For aqueous and nonaqueous samples
- Double-junction Ag/AgCl eliminate measurement and clogging problems when used in research with Tris buffers
