FAQ

Can I order a replacement plunger for my syringe?

Most Gastight syringes have replacement plungers available under 'Accessories' on the product page, while Microliter syringes do not. 7000 series modified Microliter syringes have zero dead volume and a small plunger wire, but it's best not to remove the needle or plunger to avoid damaging the wire.
