Glass bottle line consists of versatile, multi-use sampling and storage containers each made of Type III soda lime. Valumetric bottles are graduated in milliliters and ounces, for use as sample bottles or for dry powders, soil samples, and for specimen storage.
Equipped with sensitive microprocessor-based PID controllers, these stationary and shaking water baths maintain temperatures from ambient +5 to 100 C with ۯ C accuracy and ۪.2 C uniformity.
Having applications in colorectal cancer, the p21 waf-1 protein is a p53-regulated gene product that mediates cell cycle arrest. Levels of p21 are reduced or negligible in tumor cells that are lacking the p53 protein or contain a mutant form of p53.
Microwave Fixation System preserves levels of enzyme-regulated neurotransmitters and metabolic substances in the brain at concentrations that exist in the living tissue, while brain size and structure remain unchanged.
Vortex autosampler consists of an integrated autosampling device and multi-stirrer, and increases efficiency, enhances precision, and promotes operator safety. The temperature-controlled, heated (up to 150 C) multi-stirrer assembly features a stainless steel tray that handles 20- and 40-ml vials.
The antioxidant system of living organisms includes enzymes such as superoxide, dismutase,
Type 3 Micro-Fluorimeter Cells not only permit stirring, but with FCA adaptors, they can also be used in a standard 12.5-mm square fluorimeter cell holder.
POLYTRON PT 1200 E handheld ergonomic homogenizer minimizes the stresses of routine and repetitive homogenization in the laboratory. With a 100-W motor and fingertip speed control up to 25,000 rpm, the 1200 E processes samples up to 250 ml.
FTIR-4000 and FTIR 6000 spectrometers, incorporated in the AccuTrac DSP mirror tracking system, provide reproducibility of interferometer mirror velocity and position resulting in a high signal-to-noise ratio.
StarBlast software program enables BLAST or text searches on DNA and protein sequence databases, using a Windows desktop machine as the server and providing a GUI interface on Windows and Macintosh platforms to interact with the server for database creation and maintenance.
GD/X Syringe Filters enable filtration of viscous samples to make sample preparation more efficient.
The Midgard Precision Current Source features a high-compliance voltage of 1000 V for injections from very small or partially clogged pipette tips. Output current level can be regulated to ۪.5%, from 0.0 to 200 MegOhms.
Chirascan Circular Dichroism Spectrometer uses double-polarizing prism optics to facilitate light throughput, particularly in the far-UV, quickly collecting quality CD spectra. Acquisition software optimizes measurements as they progress and ensures that results are meaningful.
Ni-NTA-Nanogold® detects and localizes His-tagged proteins using electron microscopy, light microscopy, and blotting. It features a 1.8-nm Nanogold particle with multiple nickel (II)-nitrilotriacetic acid (NTA) functionalities incorporated into the ligands on the surface of gold particles.
R5 Central Laboratory Vacuum Systems come equipped with special seal material, a purge assembly to remove condensable vapors from the pump prior to shutdown, corrosion-resistant components in the exhaust box, and an exhaust flange adapter to permit remote exhausting of a variety of gases.
