ND 20 ROUND BOTTOM | Rounded bottoms and shoulders are more sturdy and allow for even heating and safer operation at high temperatures Increased wall thickness (1.2 mm) compared to standard chromatography vials (0.9 mm) Vials with bevelled/HS finish feature a tighter seal due to a reduced sealing surface between crimp and glass Rounded bottom vials are ideal for automated transport: the vial drops more easily into heating blocks and racks Packed in re-closable, tamper-proof evident PP-boxes for protection against contamination during transportation and storage Can be used in combination with standard aluminium seals, magnetic seals or pressure release seals |
