Thank you for your quote request, we will be in touch shortly.
Reusable tool for the professional user. For many applications, particularly where larger plankton are being analysed, there is no requirement for a counting grid printed onto the slide, hence the introduction of this slide with a plain glass base. This chamber can be used with either upright or inverted microscopes.
The S53 can be used in conjunction with an eyepiece reticle, such as a Whipple grid (NE29), where detailed counting/sizing is required.
