Spare Pyrex® Glass Tube Only for LPV (Specify Original LPV Tube)
Product No. Price Each Action
This item cannot be purchased via shopping cart; please contact Customer Service for current price and availability.

Try our family of novel low pressure/vacuum tubes for NMR and EPR experiments as an alternative to other similar tubes. A 4X larger sealing surface eliminates leaks and greatly increases its lifetime when compared to traditional gas-tight tubes. It continues to offer a convenient flame-free sealing solution for air sensitive or volatile liquid samples at any pressure from vacuum to pressure slightly above 1 bar.

Featured highlights:

Greaseless PTFE piston provides a 100% contamination-free seal.

Axial symmetric design guarantees its application in spinning experiments.

More economical to reduce experimental costs

Reliable - standard sizes can ship within 1-2 business days after receipt of order.

Spare/replacement Pyrextube available*

Description: Spare Pyrex® Glass Tube Only* See Below

*LPV Tubes consist of 3 parts - 5 mm Pyrex® vacuum adapter, 5 mm PTFE vacuum lock valve and piston assembly and an NMR tube with the threaded glass section sealed on; also known as the spare tube.
For Spare Tube orders the original LPV part number must be specified; i.e. 528-LPV-7 as "X" denotes the style (528) and length (7").

Important Note:Product numbers that include "PQ" belong to our Precision Tube Family with an OD and ID tolerance of 0.013 mm. Those with "SQ" are not Precision and their OD and ID may vary as much as 0.4 mm. For EPR experiments that must estimate electron spin density and/or produce highly repeatable signal amplitude between different runs we strongly recommend our Precision EPR Tube.

Due to the nature of glass, Extreme Caution should be exercised when using at elevated or reduced pressures since a tiny scratch on the glass surface would significantly lower the tensile strength. Adequate safety shielding should always be used when working in these conditions.
