Stuart SRT Roller Mixers Series

SRT Roller Mixers Series

 

These roller mixers provide a gentle, but highly efficient, rocking and rolling action. The six rollers design has a small space saving footprint, while the nine roller unit has a higher capacity

Control is through a simple on/off switch and the unit will run continuously at the fixed speed of 33rpm

Recommended for mixing blood samples, viscous substances and liquid-solid suspensions where minimum aeration is required. Units can be used in incubators up to 60°C and humidity up to 80%, or in cold rooms down to 4°C.

Both roller mixers are robustly constructed and designed for easy cleaning, having plastic rollers and a drip tray to collect accidental spillages.

Stuart SRC Recirculating Cooler Series

SRC Recirculating Cooler Series

 

With all the features of the SRC4 the SRC14 is ideal where larger volumes are required, or when extra cooling capacity is needed, electron microscopes for example. The unit is floor standing with lockable easy roll castors to ensure excellent mobility.

The recirculating cooler offers powerful cooling for an external device. By accurately controlling the temperature of your cooling medium down to -20ºC, efficiency of operations such as condensing can be greatly improved. A recirculating cooler is not only much more powerful than conventional water cooling, but is also an ideal alternative when water consumption is an issue for economical, environmental or practical reasons.

Stuart SMP Melting Point Series

SMP Melting Point Series

 

The SMP10 and SMP20 have been designed with safety and ease of operation in mind making it ideal for use in education. The temperature is selected, measured and displayed digitally making it accurate and negating the need for a thermometer. The SMP10 displays temperature to 1 degree resolution while the more advanced SMP20 has a 0.1 degree resolution as well as a variable ramp rate and hold key so that the exact melt temperature can be recorded.

Two samples can be tested simultaneously. They are viewed via a magnifying lens with clear observation aided by built in illumination. Extendible back feet allow the unit to be operated at the optimum viewing angle. Full access to the block aids cleaning. The simple to follow instructions are printed directly on the instrument in most European languages for ease of use.

Stuart SI60 Incubator, Total Visibility, Analog

SI60 Incubator, Total Visibility, Analog

 

Constructed from clear Acrylic® polymer to give total visibility of samples at all times. Designed for easy access with hinged front door panel. Each side panel has 2 x 10mm diameter plugged holes for the introduction of either gases or cables. The incubator does not have a base so that it can be placed directly over complete instruments (base is available as an accessory). Forced air circulation and electronic temperature control ensure accurately maintained conditions.

For analogue model SI60, setting the temperature is via a calibrated knob. For digital model SI60D, setting the temperature is more accurately achieved via the LCD display. The latter also gives a constant reading of actual temperature. Both models have a push switch pre-set at 37°C. Additionally there is a temperature safety cut-out set at 72°C.

Stuart SI505 Microtitre Plate Shaker Incubator

SI505 Microtitre Plate Shaker Incubator

 

The SI505 has been designed specifically to combine a bench top laboratory incubator with the specific mixing action required for microtitre plates.

Shaking is ideal for mixing microtitre plates, combining a high speed action between 250 and 1250rpm with a tight orbit of 1.5mm. This enables even the smallest of vessels to adequately mix, be it well plates or microtubes. The SI505 has independent control of speed and temperature to avoid accidental temperature adjustment. Speed is microprocessor controller and set via the digital LED control panel. The unit also incorporates a versatile timer, which can be set from 1 second to 9 days, once the timer has run down, an alarm will sound and the shaking action will cease, for safety reasons the incubator will continue to run.

The temperature of the incubator can be set, via the digital LED control panel, between ambient temperature +7oC and 60oC. Careful control of the air distribution within the incubator ensures temperature uniformity throughout the sample chamber. To minimize sample evaporation the SI505 is supplied with stainless steel water trays, these are strategically placed within the unit to maintain a humidity of up to 80%, thus dramatically reducing sample evaporation over a 24 hour period.

Stuart SI500 and SI600 Series Incubator, Orbital Shaker

SI500 and SI600 Series Incubator, Orbital Shaker

 

These combined shaker and incubators are ideal for scientists doing cell culturing procedures, especially suspension culture applications. Both units are compact enough to be positioned on the laboratory bench.

The shaker provides an orbital shaking motion, adjustable between 30 to 300rpm with a gentle start action. The shaking speed is microprocessor controlled and set via the digital LED control panel. The incubator also incorporates a versatile digital timer which can be set from 1 second to 9 days. After the timer has counted down the shaking action will stop and an alert will sound, as a safety feature the incubator will continue to run.

The incubators feature smoked acrylic windows in the door and to both sides to allow easy visibility of the samples. The incubators temperature is set via a separate bright LED display, encoder control ensures that the temperature can be quickly set between ambient temperature +5°C and 60°C. Forced air circulation ensures uniform heating of the load.

Both Incubators have a versatile clamping system which secures most sizes and mixtures of flask up to 1 litre on the SI500 and 2 litre on the SI600. Typically, the SI500 platform will accommodate the following Erlenmeyer flasks: 12 x 250 ml, or 9 x 500 ml or 6 x 1000 ml while the SI600 can accommodate the following: 6 x 2000ml, 9 x 1000ml or 15 x 500ml.

Stuart SI30H Hybridisation, Incubator & Shaker

SI30H Hybridisation, Incubator & Shaker

 

A very versatile 20 litre hybridisation incubator and combined rocker shaker which only requires a minimum of bench space. The incubator temperature is accurately set via the easy to use encoder controls and displayed by a bright LED. Forced air circulation combined with microprocessor control means outstanding temperature uniformity.

The `safety first’ design includes an over-temperature protection system that automatically tracks the set temperature and controls the heater in the event of a fault. The smart system displays error codes indicating a fault has occurred or if the set temperature has been interrupted. The incubator also cuts power to the motor if it overheats or stalls.
The incubator has a stainless steel interior, whilst the door is constructed from a double glazed panel of smoked acrylic and polycarbonate to provide radiation protection. The `up and over’ door mechanism gives excellent access to the incubator.

Stuart SI19 Microtitre Plate Incubator

SI19 Microtitre Plate Incubator

 

Specially designed for use with microtitre plates, which can be difficult to incubate. In conventional incubators, when 4 or more plates are placed on a shelf, they block the air circulation, which can seriously impair temperature distribution.

The Stuart SI19 Incubator overcomes this problem with forced air circulation, which blows preheated air across the shelves rather than just through them. Microtitre plates are also prone to drying out during incubation. The SI19 overcomes this with a water tray to increase the humidity within the chamber.

The bright LED display indicates temperature and the encoder control allows rapid and accurate temperature setting. An integral over-temperature protection system automatically tracks the set temperature and controls the heater in the event of a fault. Error codes are displayed if a fault has occurred or if the set temperature has been interrupted.

Stuart SHM Series Homogenizer

SHM Series Homogenizer

 

The Stuart ® SHM1 is a powerful, variable speed, homogeniser. The high-speed, high-torque motor makes the unit ideal for most homogenising applications. During operation the rotor shaft, which is directly coupled to the motor, spins at up to 35,000rpm. The tube assembly that its around the shaft remains static and as the rotor shaft spins, within the tube assembly, it creates a pumping action drawing the sample into the open end of the tube, or probe, and forcing it through the windows at the bottom of the tube assembly. This shearing action reduces the particle size of the sample. In addition the speed differential between the rapidly moving rotor, and the static tube assembly creates cavitational force, further dismantling the sample to additionally reduce particle size.
