Nuclepore polycarbonate filters contain uniform, cylindrical pores, preferentially etched into the membrane, allowing for an even distribution of a collected sample in one plane across the entire exposed membrane surface. Contaminant-free, these microporous screens are biologically inert, and offer excellent chemical resistance and thermal stability.
Use only the highest quality cryogenic labware to reduce evaporation rates of expensive coolants. These dewars are designed for storing and dispensing small quantities of liquid nitrogen. Constructed from materials of the highest performance and quality, these containers are not only rugged, robust, and dependable, but also have very high thermal efficiencies.
The SPI Supplies Module Sputter / Carbon Coating System is designed to be a modular piece of laboratory sample preparation equipment. This design allows the user to customize a system to meet their exact needs. To learn more about the setup and operation of the SPI Supplies Module Sputter / Carbon Coater
Welcome to the Internet's largest offering of high quality tweezers. Most of the tweezers sold by SPI are made in Switzerland, and are the very highest quality tweezers anywhere in the world. At this point in time all gold plating and PTFE® coating of tweezers are also done in Switzerland, and for the same reason - we just have not found anywhere in the world that can match the high Swiss quality.
