Ultra Low ULT Laboratory Freezers From Operon

The latest ultra-low temperature (ULT) freezers from Operon, distributed in the UK by White Horse Scientific, include a choice of upright models with advanced features and options to suit a variety of users.

Customers can choose between single-door and double-door versions. With double doors, samples required less frequently can be left undisturbed in one half of the freezer while others are accessed more regularly.

A validation-refrigerating ULT can be selected for applications in which temperature reliability is crucial. An independent-control ULT offers the facility to maintain different samples at different temperatures. Platinum 100 Ohm / RTD temperature sensors deliver a high level of accuracy.

A vacuum relief port allows easy opening of doors, and the presence of four inner doors in each chamber minimises the loss of cold air while accessing samples.

Double-sealed silicon gaskets help to ensure stability. The freezers also benefit from 130 mm of high-density polyurethane foam insulation. Where appropriate, a rim heating system is used to prevent accumulation of ice on the gaskets.

As well as their distinctive and attractive design, features common to all models include a hygienic, corrosion-resistant, stainless steel inner chamber, a high-impact powder coat finish and a washable condenser filter. Other conveniences include adjustable shelves and heavy-duty castors.

In all models the controller is mounted at eye level. Door and data locking functions are available to safeguard against accidental changes to temperature programmes. In the event of a power failure, an automatic timer restart system comes into play.

Audible and visual alarms alert users when there is a power failure, if the temperature suddenly rises or if a door is left open. There is also an indicator to remind users when the condenser intake filter is due to be cleaned.

The refrigerant system itself is CFC-free. It features a specially designed high-capacity, air-cooled condenser and an aerodynamic fan. Thanks to an exclusive LBP hermetic compressor, operation is quiet and efficient.
