Techne digital Gelation Timers are designed to test how long a sample or product needs to set from a liquid into a solid gel during polymerisation.
Designed to discriminate between the viscosity of a liquid and the elasticity of a gel, the Techne Gelation Timer determines the gelation point of a range of compounds with high accuracy and reproducibililty.
The timer includes push-button operation, a bright LED display and the facility for mounting on a retort stand.
When gelation occurs the digital timer stops automatically, indicated with an audible bleep and light.
Two models are available: the 1rpm GT-5 shows times in one-minute increments up to 9,999min, while the 10rpm GT-6 version displays to the nearest tenth of a minute, making it suitable for materials with shorter gelation times.
Rob Skehens, marketing director, Bibby Scientific, said: 'The Techne Gelation Timer is a valuable tool in diverse quality-control applications, such as in the food industry, where gelatin and other setting or thickening agents are used as ingredients; for pharmaceuticals that require tablet coatings containing gelatin; for development of adhesives and polymers, including flooring compounds; and in the manufacture of agarose and polyacrylamide gels for life-science analytical techniques.' Available accessories include three sizes of stainless-steel plunger (removable for easy cleaning), packs of disposable plungers and sample cups.
