If you take measurements in alkaline environments, now you can use buffer solutions at pH 9.18 in addition to the pH 10 buffer. This means better accuracy and versatility, especially with microprocessor pH meters, which can be calibrated at both pH 9.18 and pH 10.

pH 9.18 Buffer Solution

All pH 9.18 solutions show the batch number, the expiration date and have a pH/temperature correlation table on each bottle. HI 5091, HI 6091, HI 70009C, HI 7009L/C and HI 8009L/C are provided with a certificate of analysis. Traceability with NIST Reference Standard
HANNA instruments buffer solutions are prepared using very pure chemicals, in closely controlled laboratories, and with pH meters calibrated with NIST references.

Handheld Homogeniser – SHM1

Ergonomic design
Variable motor speed 5,000 to 35,000rpm
Processing range from 0.03ml-100ml
Can be used with robust polycarbonate disposable probes or stainless steel onesThe 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 fits 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.

The SHM1 is lightweight making it comfortable to use, and most samples can be processed within thirty seconds. For longer processing the unit can be stand mounted using the included post clamp assembly. A retort stand is available separately.

The SHM1 can accommodate a selection of stainless steel probes for larger and tougher samples and also our polycarbonate disposable probes. Disposable probes are suitable for hard tissues and ideal where cross contamination is of concern. If necessary disposable probes can be easily dismantled and autoclaved up to seven times. Through careful selection of probe type, samples of 0.03ml to 100ml can be processed.

All Stuart® homogenisers are supplied with a tool kit for dismantling the rotor probes for easy cleaning.

These homogeniser probes have been designed specifically for use with the Stuart® range of homogenisers.The disposable probes are manufactured from robust polycarbonate, and can either be disposed of after each sample or autoclaved, up to seven times. Ideal where cross sample contamination is of concern. Please note that it is necessary to use the disposable probe adaptor SHM/ADAPT, available separately, to use these probes with both the SHM1 and SHM2.

The stainless steel probes are available in a variety of sizes to suit your processing needs, all are precision engineered and suitable for autoclaving. The stainless steel 5mm probe comes with a flat end, all other probes have a saw tooth end and are capable of processing hard or frozen tissue.

The SHM/STAND has been purpose built to hold the Stuart® homogenisers, it couples directly to the SHM2 and attaches to the SHM1 clamp holder, included with SHM1. The stand is heavy duty to remain stable during use and comes with a rubber coated base to help stabilise samples during processing.

March 2010 sees the launch of new Techne thermal cyclers. The feature-packed TC-PLUS can be combined with Satellite units giving complete flexibility to configure any multi-block format.The new thermal cyclers have one of the fastest aluminium blocks on the market, delivering greater uniformity than a silver block and therefore more reproducible PCR results. The 5.7 inch VGA colour touchscreen with graphical display is intuitive and easy to use. All buttons are large enough for fingers – so no stylus, pen or spatula needed!The TC-PLUS features a unique CD-type sample drawer. The force used to push the drawer in also lowers the heated lid into position, applying the correct pressure onto the samples to prevent evaporation. This mechanism is entirely mechanical and doesn’t rely on motors. All consumable types can be accommodated, from 0.5ml tubes to 384-well plates, sealed with either heat or adhesive seals.Rob Skehens, Bibby Scientific Marketing Director, commented: ‘PCR is an important tool in many research, diagnostics, forensic and testing laboratories. The new Techne TC-PLUS thermal cyclers meet key needs for speed, flexibility and ease of use, as well as incorporating stand-out innovations such as the automatic non-motorised heated lid and energy-saving Thermal Energy Recovery System (TERS™).The stackable design and PC software enable multiple TC-PLUS cyclers and Satellites to be networked, for high throughput PCR, using 96-well or 384-well blocks. Satellite units can be controlled from the TC-PLUS server or a PC but have no user interface. The next generation PC software can be used with all current and previous generation Techne thermal cyclers.

There is a choice of easily interchangeable blocks – 96 x 0.2ml, 60 x 0.5ml and 384-well plate – all with gradient for efficient optimisation of PCR conditions. With over 20 years experience in the design and manufacture of thermal cyclers, Techne is established as a leading supplier and the TC-PLUS is covered by a 4-year warranty (4 years or 100,000 cycles for blocks).

Bibby Scientific will be exhibiting on stand B2.217 at Analytica 2010, 23-26 March in Munich, Germany.

A comprehensive range of temperature controlled liquid baths are available from Techne.
Twenty different water bath combinations allow the use of accurate temperatures from -40°C up to 250°C; ensuring a solution for most laboratory and Calibration applications.
