流变一致性频率决定了产品的可取为特定的应用。例如，树脂的表面涂料，涂料制造中的粘合剂。因而实验室精确的测定凝胶时间是生产配方和工艺条件所必要。

Rheological consistency frequency determines the desirability of a product for a particular application. For example, in resins for surface coatings, in paint manufacture, in adhesives. As a result the accurate laboratory determination of gelation time is necessary for the adjustment of manufacturing formulations or control of processing conditions.

利用Techne胶凝计时器的机械压缩试验优于其它方法的，例如，凝胶溶胀试验，搅拌试验，SP1凝胶时间，因它可重复的凝胶化时间与物理化学形成胶体液时间一致。该仪器对弹性而非粘性流体的变化十分敏感，因而提供了更一致和可重复的结果。

The mechanical compression test utilized by the Techne Gelation Timer is preferred over other methods, for example, gel swelling test, agitation test, SP1 gel time, because it provides repeatable gelation times consistent with the physical and chemical change in the gelating fluid. The instrument is sensitive to elastic rather than viscous changes in the fluid and as a result provides more consistent and repeatable results

GT-5/6胶凝计时器

GT-5/6 Gelation Timers

型号GT-5/6结合一个可移动的不锈钢柱塞被测液体垂直往复运动的机械装置。凝胶发生时产生的弹性材料支持柱塞的重量导致仪器内部的一个开关关闭,时钟停止,指示灯开启。型号GT-5读取到最近的一刻。型号GT-6，精确到0.1分。柱塞的重量保持准确，有效重量作为仪器往复移动机制的一部分，以确保相同仪器或不同仪器之间的结果一致。应用于柱塞的往复运动的小振动来克服摩擦。

Models GT-5/6 incorporate a removable stainless steel plunger which is reciprocated vertically by mechanical means in the liquid under test. When gelation occurs the resulting elasticity of the material supports the weight of the plunger causing a switch inside the instrument to close,the clock to stop and an indicating light to come on. Model GT-5 reads to the nearest minute. Model GT-6 to the nearest 0.1 minute. The weights of the plungers are accurately maintained and the effective weight as part of the reciprocating mechanism in the instrument to ensure consistent and repeatable results with the same instrument and between different instruments. A small vibration is applied to the reciprocating motor of the plunger to overcome friction
