The 1000 series is a mid volume Gastight® syringe. Gastight® syringes are ideal for dispensing both liquids and gases. They have a precision machined PTFE plunger tip which creates a leak-free seal. With the tight fit, the tip essentially wipes the interior of the syringe barrel free of sample. This feature is particularly useful with heterogeneous samples as it reduces the chance that a deposit will occur and cause the plunger to freeze.
