Control the ultrasonic power to clean a wide range of instruments with Cole-Parmer Ultrasonic Cleaners. Available in digital and analog series, both feature a pulse function for 20% increase in ultrasonic power for hard-to-remove soil and pastes and an adjustable temperature range from 30°C to 80°C in 5°C increments to accommodate sensitive items and instruments. A sweep function ensures uniform sound and power throughout the entire bath. With the latest in ultrasonic cleaning technology, these are ideal for the lab or the process floor. Along with the above features, the digital series comes in six different sizes and features seven convenient operating modes. Use the normal mode for mixing, dissolving, and dispersing samples, and the degas mode to quickly remove air from HPLC samples and solvents. The dual-selection power control allows the user to choose 37-kHz operation for standard and industrial applications or 80 kHz for smaller or more delicate cleaning needs. The pause function allows for temporary operation interruption, and autostart mode will begin operation once the preselected temperature is reached. The cleaners can be set to operate continuously or in timed runs, from 1 min to 30 min.
Zeta Potential Instrument
The Stabino II from Analytik is a fast, easy-to-operate zeta potential instrument for analyzing and optimizing the stability of colloids and dispersions, based on measurement of streaming potential. Many analytical systems for determining stability are based on electrophoresis techniques that rely on a limited number of low-resolution measurements of the zeta potential. These systems can be slow and imprecise, leading to inconclusive analysis of the colloid/dispersion stability and incorrectly formulated products. Based upon rapid pH and polyelectrolyte titrations, the unit enables rapid, precise, reproducible measurement of the surface charge of particles in the range of 0.3 nm to 300 µm in just minutes. With each measuring point, the Stabino II provides valuable information about the conductivity, zeta potential, streaming potential, temperature, and pH of your sample.
Extended-Range Non-Browning Zoom Lens
Resolve Optics new Model 192-001 non-browning 6x zoom lens offers high performance over an extended 24mm–144mm focal-length range, making it perfect for remote monitoring tasks in nuclear reprocessing and power plants. The compact lens’s speciality glass components can withstand long-term exposure to radiation—up to a dose of 100 million RAD—without loss of transmission and minimal color change. Operating at f/3.6, the lens provides good image resolution and minimum geometric distortion from 400 nm–750 nm. When focused at infinity, it maintains focus throughout the zoom range without the need to refocus. Available in 1/2-in. and 2/3-in. image formats, the C-mounted Model 192-001 can be simply mounted on Newvicon tubes, Chalnicon tubes, and charge-coupled devices.
Cell-Free Nucleic Acid Extraction
The cfPure Cell Free DNA Extraction Kit from AMS Biotechnology is a magnetic bead–based DNA extraction kit designed to isolate circulating cell-free DNA (cfDNA) from human plasma or serum samples. Using a simple, automation-friendly protocol, the kit allows users to quickly extract high-quality cfDNA that is ready for use in downstream applications, including next-generation sequencing, bisulfite sequencing, PCR, quantitative PCR, droplet digital PCR, and other demanding applications. This optimized protocol gives highly reproducible results and higher yields relative to other magnetic bead–based methods. Using silica-coated paramagnetic particles, cfPure kits were developed to ensure efficient recovery of 100 bp–500 bp DNA fragments, in order to maximize recovery of low-molecular-weight cfDNA. Designed for scalability (100 µl–10 mL of serum or plasma), cfPure kits enable you to use just the number of beads and amount of reagent you need for your cfDNA extraction.
Thorlabs announces its latest addition to their product lineup for the rapidly growing field of quantum photonics, a correlated photon-pair source. The availability of a robust, high-brightness photon source is critical to the quantum photonics community for any number of applications spanning from fundamental photon-matter interaction to device characterization. The design features a user-adjustable, fully integrated 405-nm pump source on the front end of a spontaneous parametric down-conversion (SPDC) device to produce greater than 450-kHz photon pairs at 810 nm. Various design considerations were evaluated to produce a best-in-class (>0.45) heralding ratio for use as a heralded single-photon source without sacrificing pair-production rates. The photon pair (signal and idler) produced in the SPDC process is conveniently fiber-coupled out of the compact room-temperature housing for plug-and-play usage.
Confocal Imaging Reader
Cytation C10 Confocal Imaging Reader combines automated digital confocal and widefield microscopy with conventional multimode microplate reading in a unique, patented design. The spinning-disk confocal module provides exquisite resolution and optical sectioning capabilities in a wide variety of sample types. High-quality components, including a Hamamatsu sCMOS camera, Olympus objectives, and laser-based illumination, deliver excellent image quality at a significantly lower price than other models. Cytation C10 also includes widefield fluorescence, brightfield, and phase-contrast optics. Its variable-bandwidth, monochromator-based multimode plate reading is based on the proven design of our market-leading Synergy products. Environmental controls enable live-cell assays, and Gen5 software makes sample detection and image capture quick and effortless. The new 3D viewer provides users with 3D reconstruction of their thicker samples captured with the confocal microscope. Cytation C10 brings affordable confocal to every laboratory.
