Grainger Power Correction Capacitor 22.5 kvar
The WEG Power Factor Correction Capacitor is a single-phase capacitor designed to improve power factor in electrical systems. It has a 480VAC voltage rating and is available in sizes from 7.5kVAR to 450kVAR. The capacitor uses dry polypropylene film dielectric material and is enclosed in a vented steel enclosure for safety. It can provide leading vars to offset inductive loads and improve power factor to 0.95 or better. This helps reduce utility costs and improves voltage regulation. It is CSA certified and backed by a 12 month warranty from WEG. The capacitor is designed for indoor installations and has built-in discharge resistors for safety during servicing.
Molecular Dimensions Cryo-EM grid-boxes, 20/pk
This new grid-box from Swissci has been developed in collaboration with Dr Jan Löwe at the MRC Laboratory of Molecular Biology in Cambridge. Backed by years of experience in Cryo-EM, it includes many improvements on current models. The Swissci Cryo-EM Grid-Box is made from a special polymer formulation, which ensures there is no sample-damaging static charging at cryogenic temperatures. No screwdriver is required since the lid is rotated with standard laboratory tweezers. No need to hand label each box and then struggle to interpret the label. Each grid-box is provided with a pressure adhesive cryo-label with a unique identification number. Each diamond-shape slot is marked by a roman numeral. The Swissci cryo-EM grid-box is the standard size for all common cryo-EM sample mounting and storage workflows. Cost-effective pricing means the grid-box is truly disposable: avoid the confusion of multiple samples having the same identification number by using each grid-box a single time.
Mitegen Ethane-Temperature Controlled Dewar By Nanosoft For Vitrobot, Precise Cryo-EM Plunge Freezing, Integrated Tool Warmer, User-Friendly OLED Control
This Ethane-Temperature Controlled Vitrobot Dewar by Nanosoft enables highly accurate and precise control of liquid ethane temperature during critical plunge freezing in cryo-electron microscopy (cryo-EM). Embedded heaters and sensors within the brass ethane cup ensure consistent temperatures, even away from the ethane's melting point, enhancing reliability and consistency in sample preparation. A unique "Snowflake Setting" maintains the ethane just above freezing, creating a thin crust of frozen ethane for optimized conditions. The integrated control box features a warming plate and air flow, allowing quick drying of cryo-tools. This robust system includes a high-quality foam dewar and a cryogenically-compatible plastic basin, both easily disassembled without tools for efficient drying via a built-in bake-out cycle. Its user-friendly interface, with an OLED screen and intuitive knob, streamlines operation, making precise cryo-EM sample vitrification more dependable and accessible.
