New Laminar Flow Cabinets With 20% More Sterile Working Area


Telstar has developed a new line of horizontal laminar flow cabinets with an innovative design that offers a larger work chamber. The TELSTAR AEOLUS H is suitable for the preparation and handling of non-pathogenic samples, which require a sterile environment.


One new feature of the cabinet is a large working space to enable users to work in comfort. The display is slightly inclined for greater visibility and accessibility, with a screen that offers intuitive


and practical colour coding to show the cabinet status immediately. The extremely low sound level is another notable feature. It is also designed to facilitate access to all the cabinet components through the front to reduce servicing time. This minimises interruption to the daily routine caused by to preventive maintenance and requalification.


Telstar Aeolus H is a cabinet model designed to provide protection for the product in an ISO 4 sterile environment, and is particularly suitable for handling non-pathogenic samples in applications relating to hospital protocols and clinical pharmacy, in vitro fertilisation, food quality control and microbiology, in vitro cultivation of plant and animal cells, microbiology and clean rooms for electronics, micromechanics and optics.


The horizontal laminar flow system enables operation in sterile and particle-free conditions based on the principle of continuous sweeping of the work area, thus guaranteeing total protection for the product.


Circle no. 344 Eco Autoclaves More Economical


Following the recent announcement that Lab3 has re-introduced the popular Boxer range of autoclaves, the first models to be released by this specialist laboratory supplies company will make up part of a developing ECO range. As the model name suggests these are designed specifically to bring greater economies to steam sterilisation applications; since steam is only generated when an autoclave operation is required energy consumption and water requirements are significantly reduced.


Two Boxer ECO models are initially being introduced by Lab3, the BL3-200-100 which has a 95 litre capacity and the BL3-200-200 autoclave with a larger 180 litre capacity. Both autoclaves offer the convenience of front loading with a load height of just 850mm, the door featuring a single action closure mechanism which makes opening and closing easier. This was a notable feature of the original Boxer brand and has been retained in the new re-engineered machines.


Both the new autoclaves are electrically heated and offer an operational temperature range up to 136°C and pressure of 2.2 bar. All parameter settings are easily made via a large, clear touch screen mounted on the front of the autoclave and once process temperature and time have been set the cycle is automatic, a graphical indication of the real-time process status being permanently displayed.


The new free-standing Boxer autoclaves from Lab3 have their chambers finished in polished grade 316 stainless steel; the BL3-200-100 with a chamber size of 480mm x 345mm x 565mm whilst the larger model BL3-200-200 measures 480mm x 510mm x 730mm. As standard each autoclave is supplied with two stainless steel loading shelves.


Only to be expected of a company with an outstanding reputation for quality and workplace safety, these Boxer Autoclaves comply with current UK and EU safety regulations. They have full Insurance Approval for pressure vessel design and construction and are CE Marked under the Pressure Equipment Directive PD5500:2000 Cat 3, Certificate Number CEN-068752/B1.


Directors at Lab3 are so confident in the build quality of the new Boxer brand and assurances of superb, durable performance all models are backed by a 3-year warranty.


Circle no. 343 New 2012 Chilling/Heating Lab Equipment


Torrey Pines Scientific, Inc announces its new 4-colour, full line catalogue for 2012/2013. The new catalogue includes: programmable multi-position and single-position digital stirring hot plates; new fully programmable chilling/heating HPLC column oven; digital hot plates and stirring hot plates; and new large surface analogue multi-position and single- position stirring hot plates.


Intrinsically Safe Flame Sterilisation


Flame sterilisation is a routine task carried out in many microbiological, clinical and life science laboratories. A new white paper from Integra describes the security features of modern safety Bunsen burners in relation to the inherent dangers of flame sterilisation using alcohol burners, gas cookers or a traditional Bunsen burner connected to a gas distribution system.


Safety Bunsen Burners were developed to ensure high safety by eliminating the risk of gas leaking and explosion inherent in using alcohol burners, gas cookers and traditional Bunsen burners. With this new generation of Safety Bunsen Burner the gas ignition is both immediate and safe as no lighter or matches are needed. Unlike traditional burners, the gas supply flows only if a gas flame is detected by the flame monitor. Advanced temperature protection, user-defined maximum burning time and alarm display features serve to protect both the operator and operating environment.


Operating from a wide range of gas cartridges - the battery powered Safety Bunsen Burner was developed to be used wherever users wish, eliminating the need for connection to an installed gas distribution system. With no interfering cables or tubes the ‘hands-free’ the DVGW certified FIREBOY Safety Bunsen Burner from Integra has been proven in


thousands of installations worldwide to be intrinsically safe and extremely easy-to-use.

Heat-On replaces Unsafe Oil Baths at Leading Australian University


Heat-On blocks from Radleys offer a safer, cleaner and faster method of heating round bottom flasks than conventional oil baths.


Looking for a safe and cost effective alternative to oil baths, chemists at a leading ‘green’ university in Australia have invested in multiple Heat-On blocks for use in their teaching and research labs.


Commenting on their existing methods, the lead chemist, said: “We purchased the Radleys Heat-On blocks in our continued efforts to improve safety in the lab, replace expensive oils and to reduce environmentally harmful oil waste. Most previous work requiring heating of reaction mixtures involved the use of oil baths, but with the high cost of silicone oils, many people were using less safe paraffin oils. Our stores also stopped stocking silicone oil because of the cost and although we found a relatively inexpensive alternative, this does seem to polymerize with monotonous regularity.”


“We investigated blocks from several different suppliers but chose Heat-On for several reasons. The main reason was that unlike ‘nested’ systems the 250ml, 500ml, 1 litre, 2 litre and 3 litre came as stand-alone blocks, so more than one person can perform a reaction at a time. The other block system we considered had several ‘nested’ sizes, so you needed the 1 litre block with a 250ml insert to do a 250ml reaction, precluding anyone else doing another reaction as the base block is already in use. The slightly higher cost of the Heat-On package is adequately balanced by the ability to set up several reactions using the separate blocks. The Heat-On blocks are also very sturdy and are compact, fitting cleanly over the hotplate without extended handles. The Heat-On blocks also have key-like handles, which can be easily fitted to remove a hot block from the hotplate after the reaction.”


“We chose the fluoropolymer coated blocks over the anodised as we felt they will be sturdier for student use. So far, they don't have a mark on them. We have also used several sizes at temperatures up to 230°C with no problems.”
