Product Overview
What Is a Servo-Hydraulic Glass Bottle Burst Tester?
A glass bottle burst tester measures the internal burst pressure of glass containers — the maximum pressure a bottle can withstand before failure. The BTG-500 uses a servo-driven hydraulic system with water to pressurize the container, delivering closed-loop precision and a safe, controlled test that meets ISO 7458 (glass containers — resistance to internal pressure). Because water is incompressible at test pressures, a glass failure produces a controlled leak rather than a violent burst, keeping operators safe and test data accurate.
Why Servo-Hydraulic Control Matters for ISO 7458 Compliance
ISO 7458 defines the method for evaluating the internal pressure resistance of glass containers used in the beverage, pharmaceutical, and chemical industries. Conventional pneumatic or standard pump testers suffer from pressure fluctuations during step holds or linear ramps. The BTG-500's closed-loop servo motor adjusts hydraulic pressure in real time, executing both Step mode (discrete pressure increments) and Ramp mode (continuous linear rise) with exact repeatability. Canadian buyers exporting to international markets rely on these precision ISO 7458 test reports to satisfy customer and regulatory requirements across the EU, UK, and North America.
Built for Demanding Glass QC Environments
The BTG-500 frame is fabricated entirely from AISI 304 stainless steel — corrosion-resistant, easy to clean, and built for the wet, aggressive environment of a glass QC line. At 130 kg and 86 × 72 × 50 cm, the unit is compact enough for a production floor or dedicated QC laboratory. Because pressurisation is driven directly by the servo-hydraulic system, the unit requires only standard 120 V, single-phase, 60 Hz power, facility water supply (1–5 bar inlet), and shop air (6–10 bar) for ancillary pneumatics — no high-pressure air compressors needed.
Why Choose BTG-500
Closed-loop servo-hydraulic precision vs. conventional air-based glass testers
| Feature | Competitor | NAPCO Canada |
|---|---|---|
| Control & Drive System | Pneumatic / Open-loop pump | Closed-loop Servo-Hydraulic |
| Pressure Range | 0–40 bar (typical) | 0–60 bar |
| Test Medium | Compressed air | Water (hydraulic) |
| ISO 7458 Test Modes | Step only | Step + Ramp |
| Frame Material | Painted steel | AISI 304 stainless |
Closed-Loop Servo Precision
Real-time servo motor feedback eliminates pressure overshoot during Step holds and guarantees exact linear Ramp rates per ISO 7458.
60 Bar Range
0–60 bar covers the full spectrum of glass container specifications — from standard beer bottles to high-pressure carbonated spirits.
Water Hydraulic Safety
Water as the test medium means a glass failure produces a controlled leak, not an explosive fragment event — critical for operator safety.
Step + Ramp Modes
Both ISO 7458 test methods in a single unit — Step mode for dwell-time protocols, Ramp mode for burst-pressure determination.
AISI 304 Stainless
Full stainless steel construction resists corrosion, cleaning agents, and spilled test water — built for a production-floor QC environment.
Minimal Infrastructure
Servo drive builds pressure internally from standard facility water (1–5 bar) and shop air (6–10 bar) — no high-pressure air compressors needed.

Applications
Beverage — Beer, Sparkling Water & Spirits
Breweries, water bottlers, and distilleries rely on internal pressure testing to verify glass bottle integrity before filling. The BTG-500's 0–60 bar servo-hydraulic range covers standard carbonated beverages as well as high-pressure sparkling products, ensuring no under-strength bottle reaches the filling line.
Pharmaceutical — Vials, Ampoules & Bottles
Pharmaceutical packaging requires pressure testing to confirm that glass primary containers — vials, ampoules, and injection bottles — meet internal pressure resistance specifications. The BTG-500 provides the closed-loop repeatability and ISO 7458 test documentation required for cGMP compliance and regulatory submissions.
Chemical — Reagent & Specialty Bottles
Chemical industry glass containers must withstand the internal pressures generated by volatile contents, especially under temperature variation. The BTG-500 tests reagent bottles, specialty containers, and laboratory glass to confirm burst pressure margins before shipment or use.
Glass Manufacturer R&D & Production QC
Glass manufacturers use internal pressure testing at two stages: R&D, to validate new mould designs and glass formulations against target burst pressure specifications; and production QC, to monitor ongoing line output and catch defective batches before delivery to customers.
Quality Control on Filling Lines
Filling operations — whether carbonated beverages, still products, or pharmaceutical fills — require incoming glass inspection to quarantine sub-specification stock. Integrating the BTG-500 at goods receiving or as a periodic QC check prevents glass failures at the filler or in the field.
