IC Series Cooled Incubators

The IC range of cooled incubators from LTE Scientific delivers exceptional performance and value. There are 4 sizes available in the range – 92-litres, 176-litres, 294-litres and 516-litres.

All models use refrigerants R290 or R600a which have a Global Warming Potential (GWP) of just 3. This combined with low energy consumption will help keep running costs to a minimum whilst reducing your carbon footprint.

Accurate temperature performance and space-efficient storage capacities are key features of the new IC range. All IC Cooled Incubators incorporate a quiet but effective fan circulation system which distributes the air evenly throughout the chamber. All models are designed to operate between +2ºC and +50ºC.

There is a choice of either white epoxy coated or stainless steel exterior finish. In addition all models can also be supplied with double-glazed glass doors. Interior finish is of a high impact-resistant and durable ABS. The entire range also has a one piece door seal which can be easily removed making the whole cabinet extremely easy to clean and maintain.

The IC200 model is an under-bench or bench-top model providing an impressive net chamber capacity of 92-litres, which makes it one of the largest under-bench/bench-top cooled incubators available. In addition, the IC200 and 300 models can be stacked (either IC200/IC200 or IC300/IC200) providing further flexibility of laboratory space.

Shelves are plastic coated and sit in tip-proof ‘U’ shaped runners.

For easy manoeuvrability, all models except the IC200 are supplied on swivel castors as standard. The IC200 is fitted with flat skids.

IC Cooled Incubators are controlled via an electronic PID controller providing close control and variation throughout the chambers. Over-temperature protection is provided via a class 2 limiter.

Mini-Lyotrap

LTE’s smallest bench-top freeze-dryer has a digital temperature display and an impressive ice capacity of 3kg (2kg in 24hrs). Taking up minimal bench space, the Mini-Lyotrap is ideal for all common freeze-drying applications and can also be used as a cold trap for single or multiple units. Min Temp -55°C.

Lyotrap

This simple to use, touchscreen-controlled bench-top model is packed with useful features. The Lyotrap has an ice capacity of 5kg (3kg in 24hrs) and incorporates an electric defrost facility. All cycles are logged and can be downloaded via USB. Real-time graphical display of temperature and vacuum is included as standard. This model offers two minimum temperature options: -55°C and -85°C.

Lyotrap-Ultra

LTE’s largest freeze-dryer has a 10kg ice capacity (6kg in 24hrs) and is designed to take up minimal floor space. With the same controls and features as the Lyotrap, the Lyotrap-Ultra is ideal for high product volumes and long running times before defrost. It is well suited for multi-user laboratories and pilot-scale applications. Min Temp -55°C.

FREEZE-DRYING USING:

FLASKS. The sample in the flask would be pre-frozen before being freeze-dried. A popular method of freezing liquid samples is to rotate the flask in a pre-freezing bath. This has the benefit of providing a thin film of frozen material around the inside of the flask which improves the efficiency and overall speed of the freeze-drying process.

Flasks are usually placed onto a suitable manifold for freeze-drying, many of which are available. Column manifolds are ideal if you are freeze-drying flasks and jars only. Drum manifolds or the acrylic chamber fitted with a manifold lid will allow more flexibility in the type of product to be freeze-dried.

TRAYS OR SHELVES. Again, product would be pre-frozen before freeze-drying. Using our shelf arrangement, samples would be placed onto the shelves directly. For drying using the tray and support option, samples would be pre-frozen in the trays provided and slotted onto the rack. Up to 6 trays could be freeze-dried at any one time. Temperature-controlled heater mats can be supplied for this application.

VIALS. Freeze-drying in vials requires the use of our manual stoppering shelf arrangement, connected to the required base unit. This stoppering system will allow large quantites of vials to be dried at once. It is supplied complete with suitable trays and an acrylic vacuum chamber. Optional temperature-controlled heater mats will allow improved drying rates.

AMPOULES. The ampoules need to be frozen before being fitted to the manifold. Ampoules can be frozen in 2 ways. They can be placed into a conventional freezer. Whilst this is a common method, freezing in this way can prolong the freeze-drying process due to the concentration of the sample. A much better way is to use a Spin Freezer. Following pre-freezing the ampoules would be freeze-dried using either a single or double manifold arrangement, each manifold capable of holding 48 ampoules. Following freeze-drying it is then normal to seal the ampoules using a fine flame technique.
