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

KNF IP65 UFEM 1.10 FT.18RCP2 Liquid Pump KNF SIMDOS diaphragm pumps offer a variety of options to su (more)it most laboratory liquid metering and dosing needs. The UFEM 1.10 FT.18RCP2 version has a liquid transfer flow rate of 1 – 100 mL/min and discreet dosing volumes of 1 – 999 mL. It is constructed with the following chemically-resistant fluoropolymer flow path materials: PTFE head, PTFE covered diaphragm, and FFKM valves. The easy-to-read display combined with a touch control knob makes programming and access of all functions very intuitive. Besides onboard manual control, this pump offers analog control, start/stop and reset/prime TTL logic control, output signal fault alarm, and RS 232 PC control. A RC control interface cable and RS 232 cable with D-Sub 9 connector are included. A foot switch for start and stop impulses is available. All SIMDOS pumps are simple and intuitive to operate, compact, and quiet, making them a welcome addition to any business or academic lab. They are effective against pressures of up to 85 psig and transfer viscous media up to 500 centistokes (reduces flow rate above 150 cSt). The integrated software permits the transfer parameters to be modified for a range of different viscosities at the touch of a button. With a durable and IP65 splash-proof design, these pumps are maintenance free, and provide trouble-free ±2% accuracy and ±1% repeatability performance. SIMDOS 10 pumps are self-priming up to 9.8 feet of water, and can run dry indefinitely without damage. Also, unlike peristaltic pumps, there are no troublesome tubing to break or fatigue. INCLUDED: The KNF IP65 UFEM 1.10 FT.18RCP2 Liquid Pump includes: - Power Cord - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty
