Compact and efficient benchtop densitometers for measuring turbidity of cell suspensions in a variety of life science applications. The densitometers are designed and factory calibrated to measure turbidity in the range of 0.3 to 5.0 McFarland units (DEN-1) 0.00 to 6.00 McFarland units (DEN-1B) with a small standard deviation. If required, they can deliver a wider measurement range (up to 15.00 McFarland units), but with a greater standard deviation.

Bench-top models for protection against contamination during a variety of DNA/RNA procedures.

• UV surface irradiation, via 1 x 25 W 254 nm open UV lamp or 2 x 30 W open UV lamp (UVT-S-AR)
• Patented high intensity UV air cleaner, 25 m³/hour cleaner-recirculator continuous air flow with 1cm UV irradiation distance
• UVlamp in the upper hood disinfects the working area, inactivating DNA/RNA fragments during 15-30 min of exposure
• UV exposure control, 24 hour digital timer
• Convenient, easy to use digital timer for accurate control of UV exposure
• White lamp provides local illumination of the workplace to optimise visual control during operations
• Shock proof glass panels, metal framework and stainless steel work surface
• Automatic switch-off of open UV light when door opened
• UVT-B-AR is available with 1 x access port or 1 x internal power socket, UVT-S-AR with 3 x internal power socket, UVC/T-M-AR with 1 x access port

Combined centrifuge/vortex mixer for microtubes and 0.2 ml strips. For independent centrifuge and vortex mixing, or mixing of an individual tube concurrently with spinning of multiple tubes. The vortex cup, located at the top of the central shaft, emerges through an opening in the closed lid. In spin-mix-spin applications, the Combispin can be used with very low reagent volumes.

• Continuous operation or short spin
• Further rotors on option: 8 x 1.5/2.0 ml + 8 x 0.5 ml microtubes or 6 x 1.5/2.0 ml + 6 x 0.2 ml microtubes or 2 x 8-well 0.2 ml stripes

360° vertical multi-function rotator for thorough mixing in tubes, with multi-segment programme.

• Multi-function: vertical rotation, reciprocation, vibration
• Continuous or timed operation for each phase
• Choice of two models with different microtube capacities
• Speed: 1 rpm to 100 rpm with 1 rpm increment
• Reciprocal rotation: 1° to 90° turning angle
• Vibration: programmable in a burst of 1 to 5 seconds
• Fully programmable sequence of functions, including pause
• Alternative platforms for larger tubes

Microprocessor controlled shaking platform providing smooth and quiet horizontal orbital motion for mixing in bottles, flasks and beakers.

• Continuous or timed operation with automatic switch-off
• Reliable direct drive system
• Automatic load balancing system
• The five interchangeable accessory platforms enable a wide choice of vessels to be used, including bottles, flasks and beakers, dishes, boxes and petri-dishes.

Smooth rocking motion for gentle sample agitation in tubes, culture flasks, dishes and boxes. Continuous or timed operation with automatic switch-off.

Drain syphon SY1: For the rapid draining of baths.

Heat exchange coil CW5: For use with precision and general purpose stirred baths. Temperature range 2 °C above coolant temperature. Coil diameter/l mm 77/55, pipe bore inlet/outlet 7mm.

PP spheres PS20: Between operating temperatures 60 °C and 100 °C and below room temperature a lid or layers of polypropylene spheres can be used. Above 100 °C a lid must be used.
