Products Overview
A high-specification liquid transmission accessory designed to simplify and accelerate FT-IR spectroscopy of liquid samples with consistently repeatable pathlengths and unmatched throughput.

The Pearl™ Liquid Transmission System uses an innovative Oyster Cell assembly that holds samples horizontally, making loading, viewing, and cleaning easier and faster than traditional vertical cells. It delivers reproducible optical pathlengths with minimal user variation — ideal for laboratories analysing oils, solvents, biofluids, and viscous liquids.
Key Features
Designed for Reliable & Efficient Liquid FT-IR Analysis

Reproducible Pathlengths Every Time
Spacer-free Oyster Cell gives pathlength repeatability to significantly less than 1 µm, reducing variability in your data.

Interchangeable Windows & Pathlengths
Choose from ZnSe or CaF₂ windows in multiple pathlengths (25 µm to 1000 µm), changeable in a flash to match different liquid properties.

Handles Viscous & Volatile Samples Easily
Oyster design plus optional injection port ensures smooth analysis for oils, greases, and other challenging liquids.

Fast Sample Loading & Cleaning
Horizontal design with a lift-and-tilt Oyster Cell lets you apply and clean samples in seconds — reducing downtime.

Wedged & Parallel Window Options
Wedged windows eliminate spectral fringing; parallel windows allow precise pathlength determination when needed.

Leak-Resistant, User-Friendly Cell Design
The Oyster Cell’s secure horizontal configuration minimizes leaks and sample loss, ensuring safer handling and consistent results — even with volatile or low-viscosity liquids.
