Overview of Qualitest OTR Testing Equipment and Barrier Analyzers
This selection of Qualitest permeability analyzers and OTR testing equipment offers technical teams an accurate, repeatable method for evaluating oxygen, gas, and water vapor transmission through flexible barrier materials. Using coulometric sensors, differential pressure chambers, and infrared detectors, each model delivers dependable transmission measurements so your facility can make confident quality release choices and speed up product screening routines.
By selecting Qualitest for material validation, packaging specialists gain uniform testing routines across different shifts and operators. The systems provide steady temperature and pressure regulation, helping your operation protect product shelf life and confirm compliance with global barrier expectations.
Compliance & Standards
Facilities manufacturing and converting barrier packaging rely on Qualitest systems to satisfy strict validation criteria. The instruments align with major international protocols across oxygen, gas, and water vapor transmission methods:
- Oxygen Permeation: Verified to test under ASTM D3985 when operating a coulometric oxygen sensor with nitrogen carrier gas on a Qualitest OTR tester.
- Gas Permeation: Built in accordance with ASTM D1434 and ISO 2556, using differential pressure to record transmission rates for oxygen, carbon dioxide, and nitrogen.
- Water Vapor Permeation: Infrared configurations run according to ASTM F1249 and ISO 15106-2. For gravimetric cup testing, setups adhere to ASTM E96 and ASTM E96M, alongside ISO 2528, ISO 12572, TAPPI T464, DIN 53122-1, and JIS Z0208.
Key Features
- Precise Thermal Regulation: Qualitest instruments provide temperature control spanning 15 to 45 °C for oxygen and infrared moisture methods, with heating reaching 55 to 60 °C on select gas and gravimetric models. This stable thermal setting keeps your test conditions uniform during long measurement runs.
- Scalable Chamber Stations: Workstations accommodate single-cell evaluations or three-cell arrangements, while automated gravimetric lines support up to 12 distinct chambers. This multi-station setup lets your team test multiple film specimens at the same time to accelerate batch clearances.
- Fine Moisture Resolution: Infrared WVTR tester units record vapor movement down to 0.001 g/(m²·24h). This low detection threshold lets you confirm the protective properties of high-barrier laminates and pharmaceutical foils.
- Controlled Differential Pressure: Qualitest gas analyzers pull vacuum levels below 10 Pa to 20 Pa alongside a test pressure of 0.1 MPa. This constant pressure differential produces steady gas migration across specimen discs for exact permeation calculations.
- Standard Specimen Sizing: Testing chambers accept sample discs measuring 100 mm to 110 mm with thicknesses up to 2 mm or 3 mm, allowing your operators to mount standard packaging films without awkward sample trimming.
Product Applications & Operating Environments
These Qualitest instruments run inside standard indoor manufacturing test bays, commercial cleanrooms, and industrial quality control stations. Major operations, including energy and oilfield service corporations as well as packaging converters, deploy these analyzers in controlled inspection rooms to assess barrier performance across distinct sectors:
- Food and Beverage Packaging: Evaluating flexible barrier films, multilayer laminates, and coated papers to prevent oxygen spoilage and moisture migration.
- Medical and Pharmaceutical Products: Checking blister foils, diagnostic packaging, and pharmaceutical sheets to protect contents from degradation.
- Specialty Films and Energy Components: Testing battery separators, nonwoven fabrics, flexible electronics, and photovoltaic sheets to confirm controlled air permeance and gas resistance.
- Industrial and Chemical Materials: Inspecting protective sheet barriers and oilfield service packaging to prevent the leakage or ingress of carbon dioxide, nitrogen, and oxygen.
