Request InfoPorvair Sciences Ltd.Porvair Sciences Ltd. has announced a black microplate and seal combination that eliminates sample degradation by exposure to light, even over long-term storage periods. Manufactured from polypropylene, the 96-deep-well micro-plate offers good heat- and solvent-resistant qualities. Using only ultrapure-grade polymer means that each black plate has near zero leachates, ensuring long-term sample integrity. The plates are supplied RNase-/DNase-free, meaning that they can be used with even the most sensitive biological samples. Offering a sample volume of 1 ml per well with round well bottoms for...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2022 IssueSpectrophotometerThe NanoDrop™ Lite Plus Spectrophotometer from Thermo Fisher Scientific Inc. is an entry-level system that allows users to quickly and easily assess sample concentration and purity ratios. ...BioPhotonics Nov/Dec 2022 IssueBeam Profiling CameraThe Ophir SP504S Beam Profiling Camera from MKS Instruments Inc. measures large and divergent beams by accurately capturing and analyzing wavelengths from 340 to 1100 nm for beam sizes from 45...BioPhotonics Mar/Apr 2023 IssuePhotodiode PhotodetectorsExtended 2.6-µm Cutoff InGaAs Photodiode Photodetectors from Marktech Optoelectronics Inc. provide high sensitivity, high speed, and low noise for nondispersive spectrometers, pyrometers, and...BioPhotonics Jan/Feb 2023 IssueViolet Laser DiodesThe HL40173MG and HL40175MG laser diodes from Ushio are 600-mW electrostatic discharge-resistant violet devices.
