96 stainless steel bolts in an anodized aluminum base. The bolts pick up liquid in the threads, transferring up to ~10 ul of liquid in the bolt threads (depending on the depth of submersion of the bolts). Ideal for those large crude volume liquid to liquid transfers.
Not for use in transferring liquids to agar plates or membranes, or colony to colony transfers on agar due to the irregularity in bolt length.
Bolt length = 24 mm, bolt diameter = 4.2 mm
