Perkin Elmer Model 343 S Polarimeter

Polarimetry is an important technique for the investigation and analysis of optically active substan (more)ces. Common applications include: Characterization of newly synthesized compounds Quality control of pharmaceutical drugs Precise quantitative analysis of sugars Selective detection of optically active components by HPLC Monitoring and control of enzymatic reactions Principle: Automatic precision Polarimeter with optical null principle by rotation of the analyzer; automatic gain control. Radiation: Na spectral lamp Spectral lines: Selectable from instrument keypad (Na 589 nm) Apertures: Selectable apertures for standard cells and microcells. Detector: Photomultiplier 1P28A. Polarizer and analyzer: Vis-transmitting polarizers Rotatory range: ± 85° Balancing speed: 1.3°/s at 50 Hz; 1.5°/s at 60 Hz. Accuracy: ± 0.002° for rotations ≤1º; ± 0.2% for rotations >1° Reproducibility: Better than 0.002° (for zero and rotational reading). Internal angular resolution: 1 x 10-4 º Integration times: 0.1s, 0.2s, 0.5s, 1s, 2s, 5s, 10s, 20s, 50s and 100s. Autozero setting: Electronically from instrument keypad at any desired position in the rotatory range. User interaction: Either menu-driven from integrated touch-keys (English, German, French, Spanish and Italian), or PC-controlled from POL WinLab or POL WinLab ES software. Display: Stand-alone operation: vacuum fluorescence display, two lines with 20 characters each. Format of results: Selectable from instrument keypad – angular rotation, specific rotation, molar rotation, international sugar scale, user-defined scale with factor and offset. Dimensions (WxHxD): 825 x 310 x 390 mm Weight: 40 kg

This New Brunswick Scientific Innova 4330 Refrigerated Shaking Incubator was removed from a universi (more)ty lab where it was surplus to requirements. The unit powers up and the incubator and shaker have both been tested (digital thermometer not included). It is in full working order. It is in reasonably good cosmetic condition, with signs of use. Internal Dimensions: 87 x 56 x 34 cm

Shimadzu TOC-V ws Total Organic Carbon Analyzer with ASI-V This was removed from a university lab wh (more)ere it was surplus to requirements. Both units power up but we have not tested them further at our facility. The lab informed us that there was an issue with repeatability, but Shimazdu told them it wasn't an issue, as only the first test was ever out. They advised them to just disregard the first test. The system is in good cosmetic condition Included are; Shimadzu TOC-V ws Total Organic Carbon AnalyzerPN - 638-91064-03No. H51604200007KG Shimadzu ASI-VModel - ASI SA24, 40ML EPN - 638-93140-02No. H52104200998SA

Ohaus ISHD16HDG Heavy Duty Incubating Orbital Shaker, 120V Temp. Range Ambient +5°C – 65°C Speed Ran (more)ge 15 rpm – 500 rpm Temp. Uniformity ± 0.5°C at 37°C Features - The exclusive Opti-Flow Forced Ventilation System utilizes twin induction or a single large fan.
