(This is the suggested replacement for 3554 and 3840) • Each well contains three 2µL conical flat bottom protein wells and one 100µL reagent reservoir • Low volume 100µL reagent reservoir saves on reagent costs • Designed for sitting drop vapor diffusion high throughput protein crystallization • Manufactured from an advanced Cyclic Olefin Copolymer (COC) with high resistance to commonly used solvents, including acetone, acetic acid, butanone, ethanol, isopropanol, methanol, DMSO, nitric acid (65%), sulfuric acid (40%), hydrochloric acid (36%), and ammonia solution (33%) and improved transparency • Allows protein crystals to be easily viewed under polarized light with minimal background interference • Low water absorption of the polymer prevents loss of protein drop volume • Reservoir numbers are embossed on each individual well for easy identification • Protein well locations conform to ANSI/SBS 384 well plate standards for robotic handling
