Electron Microscopy Sciences CoverWell™ Perfusion Chamber 1 well with 350 µl volume
CoverWell Perfusion Chambers allows up to 16 different specimens on one coverglass. "Press-to-Seal" covers form water-tight, multiwall cell incubation or cytochemistry chamber when pressed to coverslips or microscope slides. Reagents can be quickly added and removed through dual access ports (1.5 mm Dia) without disturbing or cross-contaminating specimens in adjacent wells. Chambers are removable for permanent mounting of specimens. CoverWell chambers are made from medical grade silicone bonded to clear, UV transparent plastic.
Volume: 350 µl
Electron Microscopy Sciences Quality Control Testing Standard Set B
Additional 1000 mesh and 2000 mesh grid included. On 32mm diameter block.
Electron Microscopy Sciences JEOL SEM Cylinder Mount 2" surface, 1/4" height, Aluminum
Cylinder specimen mounts are for use with JEOL scanning electron microscopes. The mounts are made from ultra-pure aluminum with a standard lathe finish.
Head: 2"
Height: 1/4"
Electron Microscopy Sciences Miller Squares Graticle NE57, 23 mm, 9:1 Large to small square
The ratio of large to small squares is 9:1. Originally designed for hematology, they can be utilized for rapid counting of any evenly spread field of particle. References: American J. of Clin. Pathol. Vol.20, 1950, page 1079. "Time Saving Device For Counting Reticulocyte." G.Brescher and Schneiderman. Practicle Haemotology – J.D. Dacy. Published by J.A. Churchill. 2nd Edition 1956 page 25.
Size: 23 mm
Divisions: 9:1 Large to small square
Surface: Glass sandwich
Electron Microscopy Sciences Pharmaceutical PSA Pattern Graticle G-57, 25 mm, Glass sandwich
This graticule was designed for the pharmaceutical industry. However, it is also useful where particle size considerations are restricted to 10 mm and 25 mm. Dots and circles give quick references for these two sizes. In addition a scale is incorporated. The microscope must be calibrated when ordering this graticule, such that the circle must equate to 1 mm on the microscope stage.
Size: 25 mm
Surface: Glass sandwich
Electron Microscopy Sciences X-Ray Window Silicon Nitride Film, 1000 µm, 50 nm
Ideal substrates for x-ray microscopy and x-ray spectroscopy techniques. State-of-the-art manufacturing and expert engineering allow for competitive prices of these windows. Made in the USA, these X-Ray windows are entirely plasma cleanable to remove organic contamination. Flat, uniformly deposited films provide consistent backgrounds with low field-to-field variability and high x-ray transmission. For high temperature and differential pressure environments.
Dimensions: 1000 µm
Electron Microscopy Sciences Walton & Beckett Graticule G22, 20.4 mm, 3:1 ratio
The Walton and Beckett graticule is for counting fibrous dust (asbestos or glass fibers) and particularly where the majority of fibers to be counted are shorter than 5 microns. The circle is divided into four by two diametrical lines scaled in units of 5 and 3 microns respectively. 3 and 5 microns are the critical measurements of fiber lengths and diameters used in fiber counting. Walton and Beckett include shapes with an aspect ratio of 3:1 or 5:1 for comparing to fibers.
IMPORTANT NOTE: The circle on these Walton & Beckett graticules must represent 100 microns at the stage and each one must be manufactured to the individual instrument. 3:1 ratio is useful where the majority of fibers to be counted are shorter than 5 um.
Size: 20.4 mm
Electron Microscopy Sciences Indexed Grid Graticle NE71, 23 mm, 20 x 20 Grid of 0.5 mm squares
Useful for particle counting, particularly when reference is needed between workers. Also, they are useful for area of specimen determinations. Index Pattern.
Size: 23 mm
Divisions: 20 x 20 Grid of 0.5 mm squares
