Perkin Elmer Model 343 S Polarimeter-cover
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.

Thermo Pierce G2 Fast Blotter System-cover
Thermo Pierce G2 Fast Blotter System

The Thermo Scientific Pierce G2 Fast Blotter is designed specifically for rapid semi-dry transfer of (more) 10-300kDa proteins from polyacrylamide gels to nitrocellulose or PVDF membranes in 5 to 10 minutes. The Pierce G2 Fast Blotter features an integrated power supply optimized to deliver consistent, high-efficiency protein transfer with commonly used pre-cast and homemade gels (SDS-PAGE) and nitrocellulose or PVDF membranes. The large cassette provides for simultaneous transfer of up to four mini-sized gels or two midi-sized gels. The blotter has an easy-to-use color LCD touchscreen interface and pre-programmed transfer methods for different numbers and sizes of gels and molecular weight ranges of proteins. The easy-touch programming feature allows custom transfer settings to be quickly created, saved and run. The Pierce G2 Fast Blotter achieves highly efficient transfer in less than 10 minutes when used with Pierce 1-Step Transfer Buffer. The instrument is also effective for standard 30- to 60-minute semi-dry transfer protocols based on traditional buffers. Highlights: Fast – transfer proteins in 5 to 10 minutes when used with 1-Step Transfer Buffer Efficient – achieve high transfer efficiency with a broad range of protein sizes (10-300kDa) compared to conventional semi-dry or wet (tank) transfer methods Integrated power supply – seamless operation between control unit and cassette provides consistent high efficiency protein transfer Easy-touch programming – access pre-programmed transfer methods or create, save and run customized transfer methods Convenient – simultaneously transfer 1 to 4 mini gels or 1 to 2 medium-sized gels Versatile – use with Pierce 1-Step Transfer Buffer for rapid blotting programs or Towbin transfer buffer for conventional semi-dry transfer methods Applications: Semi-dry Western blot transfer of 10-300kDa proteins from polyacrylamide gels to nitrocellulose or PVDF membranes Including: 2x Pierce Power Stain Cassette 1x Pierce G2 Fast Blotter Cassette

Du-Pont Qualicon Bax System QTC-1200 Real Time PCR System-cover
Du-Pont Qualicon Bax System QTC-1200 Real Time PCR System

The Bax system is genetics based screening method that quickly and accurately detects target bacteri (more)a in raw ingredients, finished food products, environmental and water samples for fast accurate results. Through the polymerase chain reaction (PCR), the Bax system provides “yes-no” answers without the need for confirmationor expert interpretation of results. Tableted reagents provide minimal hands-on time using standard laboratory techniques in addition to accuracy, long shelf life and consistency. The Bax system cycler/detector provides even more ease of use through automated amplification and detection. Just load your samples and walk away. Electronic results that are clear, reliable and easily store are available in about four hours. Automated cycling, detection and analysis High capacity load of 96 samples per batch Single platform and protocol for all organisms allows testing for multiple targets in the same batch Electronic record of data for easy storage, retrieval and printing Pre-packaged PCR tablets have build-in control and ingredients to overcome PCR inhibition Excellent inclusivity and exclusivity for all targets No confirmation required Clear and reproducible results, independent of operator technique Minimal hands-on time using standard laboratory techniques Results as quickly as the day of sampling Performance meets or exceeds gel-based Bax systems Including software
