Konica Minolta Sensing Americas, Inc. Ramsey, N.J. has launched two new benchtop spectrophotometers: the CM-3600A & CM-3610A. The CM-3600A (pictured) is billed as a versatile instrument that can handle a wide variety of applications for measuring reflectance and transmittance of solids. (With optional accessories, it can also measure transmittance of liquids.) Its footprint is about the same as a laptop computer. The sample holder opens a full 90° for easy positioning and is equipped with a “soft-close” mechanism that prevents it from slamming shut or damaging samples. The cover of the sample viewer has a mirror to allow the sample position to be checked without moving from your seat.
The CM-3610A provides a different kind of versatility in a vertical-format, bottom-port spectrophotometer. Its piston-type sample holder simplifies sample positioning. It can be locked in the down position to enable removal of any obstructions when first inserting samples. It can then be released so that its piston moves smoothly upward to firmly hold samples in position. The bottom-port design enables easier handling of sheet materials, and it can also be used to measure powders or gels in a Petri dish. As with the CM-3600, it comes with a sample viewer to see exactly what area is being measured, and it can also measure transmittance and reflectance of solids (but not liquids).
