HOZAN Z-76A GLASS ALCOHOL & SOLVENT DISPENSER BOTTLE TECHNICAL MANUAL
====================================================================================================
1. PRODUCT OVERVIEW & WORKBENCH APPLICATION
----------------------------------------------------------------------------------------------------
The HOZAN Z-76A is an industrial-grade, ESD-safe push-type liquid dispenser engineered specifically
for electronics rework benches, cleanrooms, and smartphone logic board micro-soldering workstations:
* Solvent Compatibility: Designed to store and dispense volatile polar and non-polar solvents,
including 99.9% Isopropyl Alcohol (IPA), PCB wash water (cleaning solvents such as Mechanic 850),
acetone, ethanol, and flux thinning agents without material degradation.
* Anti-Static / ESD Protection: The heavy borosilicate glass body combined with metallic brass pump
fittings avoids static charge accumulation common in standard polyethylene (HDPE/LDPE) squeeze
bottles, preventing electrostatic discharge (ESD) damage to sensitive ICs during board washing.
* Spill-Proof & Anti-Evaporation Seal: Precision-machined spring-loaded piston mechanism features
tight vapor sealing that limits atmospheric exposure, curbing solvent evaporation and bench vapor.
2. METROLOGY & PHYSICAL DIMENSIONS
----------------------------------------------------------------------------------------------------
* Liquid Reservoir Capacity: 180 ml (functional liquid fill line) / 200 ml (overflow capacity).
* Unit Weight (Empty): 250 g (high center-of-gravity stability to prevent accidental tip-over).
* Footprint Dimensions: 53 mm (width) x 53 mm (depth) square profile with bevel-radiused corners.
* Vertical Profile:
- Bottle Base to Shoulder: 103 mm
- Overall Height (including cap assembly): 122 mm – 125 mm
- Pump Head / Dust Cap Diameter: 22 mm
* Base Rim Clearance: 55 mm footprint envelope for workstation tool caddies.
3. PUMP MECHANISM & INTERNAL HYDRAULIC DESIGN
----------------------------------------------------------------------------------------------------
* Brass Suction Core: The central fluid delivery pipe and valve seat are fabricated from corrosion-
resistant brass alloy, eliminating swelling, hardening, or plasticizer leaching into pure solvents.
* One-Way Anti-Reflux Ball Valve: Employs a spring-loaded stainless-steel check ball that permits
unidirectional upward suction upon downward depression. Liquid pumped into the top dispensing dish
cannot flow back into the lower reservoir, maintaining chemical purity.
* Concave Solvent Dish: The top pump head features a saucer-like well designed to pool 0.5 ml to 1.0 ml
of solvent per stroke, allowing direct wetting of lint-free wipes, ESD swabs, or horsehair brushes.
* Sealed Hinged Dust Cover: Integrated flip-top cap protects the dispensing well from airborne dust,
solder splatter, and vapor escape when not in use.
4. MAINTENANCE, CLEANING & WORKSHOP SAFETY
----------------------------------------------------------------------------------------------------
* Solvent Swapping Protocol: When changing between different chemical agents (e.g., transitioning from
flux wash solvent to high-purity IPA), empty the vessel, rinse the glass reservoir with pure ethanol,
and pump clean solvent through the brass core for 5–10 strokes to clear internal valve passages.
* Suction Core Unclogging: If rosin flux or solder paste residue enters the upper dish, clean the brass
orifice with a solvent-soaked swab; never use rigid steel wire that can scratch the internal ball seat.
* Chemical Storage Limitations: Not intended for concentrated hydrofluoric acid or strong mineral acids
that etch silicate glass. Avoid storing chlorinated solvents for extended multi-month dormant periods.
