26 Benchtop Autoclave with Larger Chamber
Design of the Priorclave H60 compact autoclave came about through a customer request for a benchtop sterilise based on the highly successful C40 laboratory autoclaves but with a larger sterilising chamber.
With a level of settings and operating flexibility usually reserved for larger autoclaves, the Priorclave H60 compact, front loading steam steriliser will enable laboratories with low volume requirements to enjoy the full benefits of a feature-packed range at an affordable price. It is ideally suited for a variety of sterilising applications such as media preparation, laboratory waste, liquids and diluents, glassware, instruments and apparatus.
TACTROL®
Developed at the company’s UK manufacturing centre, the H60, a 60 litre benchtop laboratory and research grade autoclave is now a key model within Priorclave’s more compact steam steriliser range and offers a 50% increase in chamber capacity. This latest model has an internal chamber diameter of 350mm, a working depth of 625mm and is available with a choice of either a single or double heating elements, giving cycle times of 90 or 75 minutes respectively. It also features the advanced 2 microprocessor control system with staged illumination providing digital readout of cycle status as well as allowing easy setting of temperature and time.
Designed for bench-mounting and easy installation, models in this versatile H60 autoclave range can be supplied for either manual or auto-water fill and come in a choice of standard or vacuum models. Appreciating that the increased external depth of the new Compact H60 steam steriliser may restrict placement on a standard laboratory bench Priorclave is able to supply a special stand to facilitate mounting adjacent to a working surface.
As a dedicated design and manufacturing centre for autoclaves, Priorclave has created one of the largest ranges of standard steam sterilisers, from compact bench-top front loading to free-standing top- loading and high capacity front-loading autoclaves as well as double-door, power-door and stackable sterilisers. It is unlikely that customers cannot find a model to meet their needs, however for one customer this was not enough.
Despite having the most comprehensive range of laboratory autoclaves there is always someone who wants something different and that is exactly what brought about the development and production by Priorclave of the H60, an autoclave with a horizontal 60 litre capacity chamber.

Premium Tensiometer Updated with New Software and Temperature Control Features
Krüss GmbH is introducing an updated version of their successful Force Tensiometer, K100, with their new ADVANCE software, and has also developed two new temperature control units for this measuring instrument.
ADVANCE software displays the logical workflow of scientific measurements on an intuitive user interface. The broad scope of methods offered by the K100 include completely automated CMC measurement and processes for characterisation of the wettability of solids and powders right up to the determination of their surface free energy. In parallel with the software release, this measuring instrument also offers technical upgrades, such as a sensor that registers the closing of the sample chamber doors.
ADVANCE controls measurement sequences with the aid of ready-made automation programs, reducing manual steps to the absolute minimum. Measurements can therefore start immediately without any further adjustments. Procedures can also be intuitively modified or even newly created for completely different sequences without any programming knowledge.
The automation programs work hand in hand with the numerous software-controlled K100 components and sensors. For example, closing the measuring chamber can initiate the next sequence step of the measurement without the user needing to confirm continuation. The integrated stirrer can switch itself on and off during the
procedure in order to homogenise the sample before measurement. During a critical micelle concentration (CMC) measurement, special Micro Dispensers are integrated in a fully automated procedure which includes creating a concentration series and evaluating the measurement curve.
An additional benefit in the K100 program innovation consists of two powerful temperature control units for different ranges. The Temperature Control Unit – TJ50 exploits the Peltier effect for tensiometric measurements between -15 and 130°C. The unit rapidly reaches the target temperature and keeps it stable due to excellent insulation. The temperature control housing of the unit also encompasses an electromagnetic stirrer, ensuring rapid homogenisation of the sample temperature. Moreover, the TJ50 includes a cooling unit for the Peltier element so that separate counter-cooling is not necessary.
The electrically heated temperature control unit TJ60 quickly and reliably reaches target temperatures of up to 300°C. It enables measurements of the surface tension of polymer melts or bitumen. The supplied disposable sample vessels made of the excellent heat conductor aluminium solve the problem of persistent contamination. Oxidation of the samples can also be avoided by connecting an inert gas.
