Stuart Hotplates & Stirrers Series

Hotplates & Stirrers Series

 

Stylish and economical general purpose hotplate designed with safety as well as performance in mind. The compact shape takes up less bench space and makes storage easier. The hotplate has microprocessor control and an innovative LED based true °C temperature setting system rather than simply a 1 to 10 arbitrary scale. The unit can also be used in conjunction with the SCT1 digital contact thermometer to accurately control sample temperature rather than plate temperature. The “Hot” warning light will flash whenever the plate temperature is above 50°C even when the hotplate is turned off and unplugged from the mains.

Model UC150 has a glass ceramic top which has excellent chemical resistance. The surface is easy to clean and allows high plate temperatures for faster heating.

Model US150 has a robust aluminium/silicon alloy top plate for excellent heat transmission. The top plate has a thin ceramic coating for added chemical resistance. A 700W element gives rapid heating and ensures even temperature distribution across the whole surface of the plate.

Stuart Aquatron Water Still Series

Aquatron Water Still Series

 

Three models are available giving outputs of 4 or 8 litres/hour single or 4 litres/hour double distilled water. The high quality PYREX® borosilicate glassware coupled with silica sheathed heaters gives pyrogen free distillate of the highest purity from virtually any raw water supply.

The unique condenser design ensures that the droplets of distilled water remain in contact with the cooling coil for the longest possible time ensuring maximum energy transfer. This produces cold distilled water ready for immediate use and pre-heats the boiler feed to increase efficiency.

All glass construction allows rapid descaling using strong mineral acids. A built in “clean” function and integral acid addition funnel make the cleaning operation simple and safe with no need to dismantle any of the glassware. A large bore ROTAFLO® stopcock with PTFE key is fitted for easy draining of chemicals after cleaning.

Stuart STR Rotator Drive Series

STR Rotator Drive Series

 

The STR4 rotator drive unit is used in conjunction with a wide range of drums designed to take different sizes and types of vessels. The five drums are designed to give different mixing actions and are listed on pages 76 to 78.

Speed of rotation is variable from 6 to 60rpm for a range of mixing applications.

For added convenience a built in analogue timer can be set from 10 to 60 minutes. Alternatively the unit can be set for continuous operation.

Drum, test-tube holder, STR4/1
Designed to rotate test-tubes in an end-over-end movement. Comprises a square metal drum which can accommodate a choice of plates fitted with tube clips. Up to four plates can be mounted on the drum. Easy fitting via a push button mechanism.

Drum, two platforms, STR4/2
This drum accepts 2 x 250ml conical flasks or reagent bottles for end over end mixing. The samples are securely held in place by a collar that fits around the neck of the flask or bottle and is secured by two washers.

Stuart SS Shakers & Rockers Series

SS Shakers & Rockers Series

 

Stuart shakers and rockers are ideal instruments for mixing and aerating various biological and chemical samples in the laboratory. All models have digital setting of both speed and an adjustable digital timer that automatically stops after the set time (1 to 9999 minutes, 1 second to 90 minutes or 1 minute to 9 hours). The SSM range comprise of personal units with a small footprint while the SSL is the larger labscale equivalent.

Model SSM1 and SSL1 provides a smooth uniform circular motion with an orbit of 16mm. Speed range is 30 to 300rpm. Max load 3kg and 10kg respectively.

Model SSL2 has a side-to-side reciprocating action ideal for vigorous shaking applications. Speed range is 25 to 250rpm. Max load 10kg*.

Model SSM3 and SSL3 provides a 3D gyratory motion, ideal for low foaming agitation, DNA extractions, staining and de-staining procedures etc. Speed range is 5 to 70 rpm. Max load 3kg and 10kg respectively. The angle of tilt can be adjusted manually, without the need for tools, between 3 and 12° (see section 4.6 for instructions).

Model SSM4 and SSL4 have a see-saw rocking action that creates a wave motion within vessels such as culture flasks, Petri dishes etc. Speed range is 5 to 70 rpm. Max load 3kg and 10kg respectively.

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.
