neochrom® Headspace vials, 20 ml, clear glass, rolled rim, 75.5 x 23 mm, rounded bottom, type Perkim Elmer, Tekmar, 100 pcs./pack

The instruments on the market require a wide variety of bottles.
To help you identify the correct bottle, we have provided information on instrument suitability in our product overview.
All bottles are made of 1st hydrolytic class glass.

Headspace bottles differ in the following characteristics:

• Volume
• rounded or flat bottom
  A rounded bottom is more stable at high internal pressure during tempering. In addition, the bottle slides more easily into the heating block when inserted there by means of magnets.
  A flat bottom may be necessary if the bottles have to run slightly downwards in the instrument.
• beveled headspace rim
  A beveled headspace rim may be necessary for some special closure systems (Perkin Elmer).
  
• Neck length (instrument-dependent)
• Clear / amber glass
• with / without title block and filling marks
