Back-illuminated EMCCD camera The Andor iXon Ultra 888 MP, backilluminated EMCCD camera offers single-photon sensitivity across a large field of view at 26 fps. It is claimed to represent a performance boost for the largest available EMCCD sensor, as well as the first USB 3.0-enabled EMCCD camera. With a 1024 x 1024 sensor format and 13 µm pixel size, the resolving power, field of view and speed of the device render it attractive and versatile for demanding applications. It has been re-engineered to facilitate a 3x acceleration of the pixel readout speed to 30 MHz while maintaining quantitative stability, propelling the full frame performance to video rate. The product is designed to be flexible yet easy to use, optimisable for a wide variety of application requirements in a single click via the OptAcquire feature. Signal can be quantitatively calibrated in units of electrons or photons, either in real time or post-processing. The camera’s technology offers automated recalibration of EM gain, alongside anti-ageing protection. Applications include: single molecule detection; super-resolution microscopy (PALM, STORM); TIRF microscopy; spinning disk confocal microscopy; vesicle trafficking; ion signalling; cell motility; luminescence; FRET/FRAP; single photon counting; voltage-sensitive dyes.

Tube rollers Stuart has updated its range of tube rollers. The products are suitable for laboratories that have demand for rolling as a form of mixing. Gentler than shaking, rolling tubes provide steady mixing over long periods of time. This makes them suitable for mixing blood samples, viscous substances and liquid-solid suspensions where minimal aeration is required. They also aid in the defrosting of samples and are designed for continuous operation. Units can be used in incubators up to 60°C and with humidity up to 80% or in cold rooms down to 4°C. The roller mixers are robustly constructed and designed for easy cleaning, with plastic rollers and a drip tray to collect accidental spillages. The addition of removable side panels and detachable roller tubes means the mixer can adapt to even more users’ needs. The user can conveniently detach the product’s roller tubes to allow large vessels to be accommodated, as well as allowing the user to mix a wide variety of differently sizes tubes and bottles. Any of the roller tubes can be removed to allow the user to choose the arrangement depending on their needs. Removable side panels provide the user with peace of mind, as samples will be mixed effectively during continued use. The side panels ensure the sample bottles do not slide off the mixer during use and, as a result, provide a high level of safety and functionality. The mixers are available with analog or digital control; six or nine rollers; and fixed or variable speed. The accessory stacking system SRT/STACK is available where bench space is at a premium.
