Standard VT Dewar Inserts

These are the most common Dewar Inserts in EPR!
WG-821 and WG-822 Dewar Inserts
Sample tubes 4mm in diameter can be used with any of these Dewar inserts. You can use 5mm tubes in those with “-F” in the product number.

Standard Length Dewar Inserts

Long Dewar Inserts

NOTE: If you need a Dewar Insert with a different diameter or length, with silvering or dimples, please contact us. Wilmad has made many modified Dewar Inserts for spectroscopists like you. Just send us information about your requirements.

Remember!
Wilmad uses “-Q” to designate versions using Suprasil in the critical portions of the cell. All other cells are prepared from Clear Fused Quartz (CFQ).

Simple Dewar Inserts

Need a simple Dewar Insert for your research?

WG-824 and WG-826 Dewar Inserts

Sample tubes 4mm in diameter can be used with any of these Dewar inserts. You can use 5mm tubes in those with “-F” in the product number.

NOTE: If you need a Dewar Insert with a different diameter or length, with silvering or dimples, please contact us. Wilmad has made many modified Dewar Inserts for spectroscopists like you. Just send us information about your requirements.

Remember!
Wilmad uses “-Q” to designate versions using Suprasil in the critical portions of the cell. All other cells are prepared from Clear Fused Quartz (CFQ).

JEOL Dewar Inserts

Why pay more for a replacement JEOL Dewar Insert?

Sample tubes 4 or 5mm in diameter can be used with the JEOL dewar inserts. Sample support dimples can be added, if needed.

Remember!
Wilmad uses “-Q” to designate versions using Suprasil in the critical portions of the cell. All other cells are prepared from Clear Fused Quartz (CFQ).

Dewar Insert for Q-Band or Loop Gap Resonators

Control temperature inside small Q-Band or Loop-Gap resonators.
WG-894 Dewar Insert

You can control the temperature of samples in small resonators by putting the entire resonator in Wilmad’s largest Dewar Insert.

Dewar Insert for TM Aqueous Cell

TM110Aqueous Cell Dewar Insert

To control your sample temperature near ambient in TM Aqueous Cells, use Wilmad’s WG-821-TMR Dewar Insert.

NOTE: Control the temperature of a TM Aqueous Cell near room temperature with this special insert; the upper section is not dewared.

High Temperature Dewar Inserts

At temperatures higher than 300 degrees Celsius, cavity heating is a problem with standard Dewar Inserts. But Wilmad’s WG-821-HT gives you a solution.

Sample tubes up to 4mm in diameter can be used with any ot these high-temperature dewar inserts.

NOTE: Wilmad does not offer a Dewar Insert for the Bruker ER4111HT High Temperature Cavity Resonator system.
