Perkin Elmer 343 Polarimeter
Description from the supplier
The Perkin Elmer 343 Polarimeter, a reliable second-hand system, offers cutting-edge polarimetry capabilities essential for the thorough investigation and evaluation of optically active substances. This instrument is vital across several applications, including:
- Characterization of newly synthesized compounds
- Quality control processes within pharmaceutical manufacturing
- Precise quantitative analyses of sugars
- Selective detection of optically active components via HPLC
- Monitoring and regulation of enzymatic reactions
Key Features:
- **Principle:** The device is an automatic precision polarimeter operating on the optical null principle through analyzer rotation and equipped with automatic gain control.
- **Radiation Source:** Na spectral lamp provides consistent illumination.
- **Spectral Lines:** Accessible via the instrument's keypad, offering Na 589 nm lines.
- **Apertures:** Customizable apertures to accommodate both standard cells and microcells.
- **Detector:** Employs a 1P28A photomultiplier for accurate measurement.
- **Polarizers:** Utilizes visible-transmitting polarizers for precise optical analysis.
- **Rotatory Range:** An extensive rotatory range of ± 85° is available.
- **Balancing Speed:** Operates at a balancing speed of 1.3°/s at 50 Hz and 1.5°/s at 60 Hz.
- **Accuracy:** Delivers exceptional accuracy, with ± 0.002° for rotations up to 1º and ± 0.2% for rotations exceeding 1°.
- **Reproducibility:** Offers reliability better than 0.002° for both zero and rotational readings.
- **Internal Angular Resolution:** Fine resolution at 1 x 10⁻⁴ º.
- **Integration Times:** Versatile integration times ranging from 0.1s to 100s.
- **Autozero Setting:** Easily set electronically through the keypad at any position within the rotatory range.
- **User Interaction:** Features both menu-driven interaction via integrated touch-keys in multiple languages (English, German, French, Spanish, and Italian), and PC integration through POL WinLab or POL WinLab ES software.
- **Display:** Equipped with a vacuum fluorescence display for standalone operation, featuring two lines accommodating 20 characters each.
- **Result Formats:** Results are customizable via the keypad, allowing outputs in angular rotation, specific rotation, molar rotation, international sugar scale, or a user-defined scale with specified factors and offsets.
- **Physical Specifications:** Dimensions are 825 x 310 x 390 mm, with a total weight of 40 kg.
This polarimeter stands as a sophisticated tool engineered for precise optical measurements and analyses, supporting a wide array of research and quality control applications.
