Introduction

## A single instrument for complete barrier analysis

**Medford, MA USA, 27th November 2023** - Labthink, a global leader in testing and
analysis instrumentation, has announced the launch of the **C406H Combination OTR
and WVTR Tester** - a significant advancement in permeation testing that offers 
unparalleled accuracy, efficiency, and versatility.

The Labthink [C406H](https://flexitest.in/packaging-testing-equipments/permeability-testing-instruments/combo-tester-6-cells-c406h/)
is designed to meet the evolving needs of industries such as food and beverage packaging,
pharmaceuticals, electronics, and materials research. By seamlessly integrating 
both OTR and WVTR testing capabilities into a single platform, this tester streamlines
the permeation testing process - allowing for the measurement of oxygen and water
vapour transmission rates within one dual-purpose instrument.

Labthink C406H - 6-cell OTR + WVTR Combination Tester  ·  Available from Flexitest
India

This comprehensive approach enables manufacturers to gain a **holistic understanding
of their materials' barrier properties**, ensuring the production of high-quality
and durable products.

Key Features

## What makes the C406H different

The C406H brings together five capabilities that were previously only available 
across multiple separate instruments:

🔬

Dual Testing Capabilities

Conduct OTR and WVTR tests independently or sequentially - providing flexibility
in experimental design and a more comprehensive analysis of barrier performance 
in a single run.

⚡

Advanced Sensor Technology

Equipped with cutting-edge sensors, the C406H ensures precise and reliable measurement
of transmission rates, even for ultra-thin or highly permeable materials.

🖥️

User-Friendly Interface

The intuitive touch-screen interface simplifies operation and data interpretation,
making it accessible to both seasoned professionals and those new to permeation 
testing.

🚀

High Throughput

With 6 test cells delivering 6 simultaneous results, the C406H enables high throughput
testing - allowing manufacturers to optimise production processes and bring products
to market faster.

📋

International Standards Compliance

Meets and exceeds ASTM D3985, ISO 15105-2, ASTM F1249, ISO 15106-2, DIN 53380-3 -
ensuring results are accurate, reproducible, and accepted by global customers and
auditors.

🌡️

Precise Temperature Control

Standard range 15–50°C ±0.15°C with optional 5–60°C configuration. Humidity control
from 0% to 100% RH for complete test condition flexibility.

CEO Statement

## Labthink International on the C406H launch

> By combining OTR and WVTR testing capabilities in a single instrument, we are 
> empowering manufacturers to gain a deeper understanding of their materials' barrier
> performance, ultimately enhancing product quality and reliability.

 - **Craig Primiani**, CEO, Labthink International

The C406H represents Labthink's commitment to consolidating complex barrier testing
workflows. For packaging labs in India handling pharmaceutical blisters, flexible
food packaging, and multilayer laminates, the ability to test OTR and WVTR on the
same specimen set - without reconfiguring equipment - translates directly into faster
qualification cycles and reduced laboratory costs.

The Labthink C406H is available for purchase in India through **Flexitest** - authorised
Labthink distributor. Full installation, calibration, and application support included.
