Rose 6x31mm Insert Clear Glass Flat Base. 100pcs/pk.

Microvolume Polypropylene inserts are recommended for pH-sensitive samples, greater solvent compatibility, biological samples, and ionic samples becasue of the material′s inertness. Micro volume vial inserts, when used in conjunction with autosampler vials, allow for maximum sample recovery and easier sample removal because the conical shape decreases the surface area inside the vial. Micro volume vial inserts can be used with screw tops, crimp top, or snap top vials. All conical styles of inserts are offered with the traditional pulled point as well as the improved mandrel point. Pulled point inserts are more economical, but mandrel point inserts provide a more pointed and uniform tip that enables better sample recovery.
