Chiaro nanoindenter is the ideal nanoindentation instrument to explore the micro-mechanical properties of cells, spheroids or other small samples. Therefore, this instrument is purposely built to measure forces on cells and micro-materials while placed on an inverted microscope Leica DMi8. The Chiaro nanoindenter is capable of measuring many mechanical parameters. These include the Young’s Modulus (E), storage (E’) and loss moduli (E”). Moreover, both, static and dynamic indentation can be performed using this instrument, including creep, stress-relaxation and DMA.
Nanosight LM20 with a LM10 laser unit (Class 1 diode 635 nm) characterizes the size distribution and concentration of all types of nanoparticles from 20nm-1000nm in solution by dynamically analysing the paths the particles take under Brownian motion over a suitable period of time.
iBright FL1500 Imaging System supports the main imaging applications of fluorescent, chemiluminescent, and colorimetric western blots, in addition to fluorescent stained nucleic acid gels, fluorescent stained protein gels, colorimetric stained protein gels, and colorimetric membrane stains.
Features of the iBright FL1500 Imaging System:
• 9.1 MP cooled CCD camera: high sensitivity and dynamic range to help enable the detection of subtle differences in samples
• Five fluorescence channels: multiplex and capture up to four proteins in a single blot for more meaningful and representative experiments
• Smart Exposure technology: provides rapid determination of optimal exposure time to help minimize the need to repeat exposures to acquire the desired signal
• Simple interface: clear layout of functions and features combined with a 12.1-inch capacitive touchscreen for a smooth imaging experience
• Advanced automated features: automatic sample rotation, automatic zoom, and automatic focus help streamline image capture
• 22.5 x 18.0-cm field of view: large field of view for high-throughput imaging (image up to four mini or two midi blots at a time)
• Green LED-based transilluminator: effectively excite popular DNA dyes such as ethidium bromide and Invitrogen SYBR Green dyes with an alternative to UV-based transilluminators
• Flexible connectivity: export captured images via ethernet connection, Wi-Fi (with optional accessory), USB, or directly to Connect cloud-based platform
• Multiple image analysis options: perform densitometry, quantitation, and normalization directly using the on-instrument software, or for more in-depth analysis use iBright Analysis Software (available in both desktop and cloud-based versions)
