Freeze Dryers
The LTE Lyotrap range of freeze dryers has been designed to suit a wide of freeze drying applications in the laboratory environment.
Mini Lyotrap
This is smallest bench top freeze dryer manufactured by LTE. Having an ice capacity of 3kg, it also represents excellent value. Taking up minimal bench space, the Mini-Lyotrap is ideal for all common freeze drying applications and is also useful as a cold trap for single or multiple units.
Lyotrap
This simple to use, microprocessor-controlled bench-top model is packed with useful features. With a 5kg ice capacity, the Lyotrap incorporates an electric defrost facility, displays temperature and vacuum parameters digitally and incorporates a safety system which prevents the vacuum pump being activated until the temperature has reached -30°C.
The Lyotrap is now available in 2 condenser temperatures: -55°C and -80°C.
Lyotrap Plus
This unique bench-top freeze dryer has all the features of the Lyotrap and also incorporates a built-in temperature controllable work chamber complete with three shelves. Four floating temperature probes allow the load temperatures to be monitored, and as an option, the unit can be monitored and controlled via a remote PC. The Lyotrap-Plus has a 4kg ice capacity.
Lyotrap Ultra
This is the largest freeze dryer in the range, with an 18kg ice capacity. Having the same controls and features as the Lyotrap, the Lyotrap-Ultra is ideal for high product volumes and long running times between defrosts. This model is well suited for multi-user laboratories and pilot-scale applications. Unlike the rest of the Lyotrap range, the Lyotrap-Ultra includes an integral vacuum pump and is floor standing, supplied with castors.
