All Microliter (700 and 800 Series) syringe barrels feature a hand-fitted plunger, so replacement plungers are not available for 700 or 800 Series syringes. To replace the barrel or the plunger, a Barrel/Plunger Assembly would need to be purchased. These replacement assemblies are located under Accessories on the product page. Replacement holder assemblies are also located under Accessories on the product page.
Gastight (1700 and 1800 Series) syringes allow for replacement plungers. Replacement syringe barrels, plungers and holder assemblies are located under Accessories on the product page.
