Request InfoMcPHERSONThe McPherson Model DP100 is a high-vacuum pumping tee with a removable conductance-limiting aperture. The tendency of pressure to equalize in vacuum systems can interfere with experiments or prevent some detectors from operating properly. The DP100’s aperture creates a transition between an area of high pressure and a vacuum spectrometer or an experimental chamber at lower pressure To best match optical systems, apertures with circular or rectangular cross sections are available. The DP100 can allow up to three orders of magnitude pressure differential, depending upon the...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Sep/Oct 2022 IssueMicrospectrophotometerThe FLEX PRO™ UV-VIS-NIR microspectrophotometer from CRAIC Technologies is a multifunctional tool able to acquire microscale images and spectra from the deep UV to the NIR.
