Transmission electron microscopes

In Transmission Electron Microscopy (TEM) a thin sample is exposed to a focused beam of electrons. The beam is modified as it passes through the sample to produce an image. This image can then be magnified with lenses and focused onto a scintillator attached to a CCD or other sensor or surface such as a fluorescent screen or photographic film. There are many different transmission electron microscopes and instruments (more) in which it is combined with other techniques to create high-resolution images.

Laboconco Labconco Evaporation System RapidVap-cover
Laboconco Labconco Evaporation System RapidVap

Original packed and unused Labconco Evaporation System RapidVap. 6 months warranty. These systems us (more)e vacuum in conjunction with heat and vortex motion to accelerate evaporation and provide an alternative to traditional centrifugal evaporation methods. The systems can be used for a wide range of aggressive chemicals. The heat is generated with a heating block system that, unlike water baths, avoids potential sources of contamination and requires no maintenance. - Fast evaporation rates: Water evaporates at a rate of up to 0.75 ml/minute/tube - Microprocessor controlled 1000 Watt heating block system: up to 100 °C - Microprocessor controlled negative pressure for evaporation acceleration - PTFE-coated aluminium chamber, glass lid with Lexan® protection - Up to nine different user-adjustable programs with different parameter setpoints that can be stored - Setting of the parameters time, heat, vortex speed and vacuum - Easy to read LCD display Suitable for seven different, interchangeable accessory sample blocks that can hold sample volumes ranging from a few milliliters to 450 milliliters. Up to 110 tubes (each 12 or 13 mm) can be loaded simultaneously. Additional blocks are available for different tube types, e.g. conical centrifuge and scintillation tubes. The maintenance-free, microprocessor-controlled motor offers infinitely variable speeds to accelerate the vortex movement up to 1000 min-1. Ideal for sample preparation in a variety of applications including drug development, agrochemistry, environmental analysis and mycology. Please note: Requires vacuum pump, block and glass equipment for operation.
