Zinsser Analytic has offered Polyvials® for over 30 years. These vials are of consistently high quality and provide extremely good seals with the self-sealing screw caps. The original application was for the 20 ml vials for liquid scintillation cocktails. The design of the bottle threads and the cap was created to solve the issue of "leaking liquids", a common problem with many vials especially when they are shipped under stressful conditions such as within air cargo holds where large temperature fluctuations cause expansion and shrinking that results in leaking. The Zinsser vials will always provide a tight and leak-proof seal even under these conditions.
For liquid scintillation, the standard vials are the 20 ml Polyvials V shown below, part number 3071400. Be sure to select your caps separately (so you have the choice of color you want). The package that included both vials and caps together as one part number is no longer available.
|Part Number||Volume||Cap Thread||Dims D x H (mm)||Pack Size|
|3071400||20 ml||22 mm||27 x 60||1000|
These caps are specially-made for Zinsser Polyvials V. They are designed with a sealing cone that provides an excellent gas-tight seal without a liner.

Minis® 2000 Series are miniature counting vials made from polyethylene with a special sealing system, for liquid scintillation counting. Caps for Minis® have inner and outer seals. They are easy to fit - simply push on and turn slightly to give an excellent seal. Just a small turn and pull will open the cap. There are two types:
MINIS® 2001 for Minivial Counters
These vials meet the IEC-Standard for miniature vial counters. The cap is flush sided and ribbed for easy handling.
MINIS® 2002 for Normal LSC Counters
Minis® 2002 with flanged cap designed to hang in a 20ml vial which can be used with all commercial scintillation counters. The best results are obtained using Polyvials® (Cat. no. 3071401) or glass vials (Cat. no. 986532).
MINIS®1000 are 4ml counting vials made from transparent polypropylene. They have specially designed flush sided caps which ensure optimum sealing. They are designed especially for BECKMAN-Gamma Counters, but are also ideal for many sample collection applications. These vials are not suitable for liquid scintillation counting due the vial dimensions and the polypropylene material, and are designed for sealing aqueous solutions rather than organic.
MINIS® M are a special “Push-On” Minivial, exclusively designed in cooperation with WALLAC for their new MICROBETA Scintillation counter.
