Description of Septa and Cap for Snap Vials
Easy to use, ideal for storing powder samples. Because it is a push-type cap, it is not suitable for transporting liquid, an audible click ensures a secure seal has been formed and that the cap is correctly aligned. The temperature range of the snap top sample vials is 0-125 ° C, and the temperature range of the cap is -40-70 ° C.
Features of Septa and Cap for Snap Vials
Small order acceptable
Pre-assembled 11mm clear snap cap with 1mm PTFE/ Silicone septum
Deformation test of septa at different Temperature
To confirm Hawach septa has no deformation at high, low, and room temperature of 100℃, -4℃, and 25℃.
Keep 10 pcs Hawach septa in three different temperature of 100℃, -4℃, and 25℃ for 6 hours separately, and then observe the deformation property under the magnifying glass.
Experiment result and discussion:
There is no obvious deformation of the Hawach Scientific Co., Ltd septa, showing that our septa have good shape keeping the property.
