Safe for you and the lives you touch



The ComfortSampler® device has glass capillaries housed in a plastic shell, which protects the therapist from broken glass. The SurGuard2™ safety needle protects against accidental puncture, allows for safe and easy disposal and follows OSHA safety guidelines.


Increased sample stability

The glass capillary tubes keep patient samples stable and cool the samples quickly. Samples do not require icing if tested within 30 minutes.


High-visibility flash

The transparent construction of the ComfortSampler device makes it easy to identify when the artery has been punctured.


Convenient packaging

The ComfortSampler® kit comes in multiple package configurations. Individually wrapped for convenience, kits contain the accessories needed to perform the sample collection. Bulk packaging options are also available to meet high-volume needs.


SurGuard2 is a trademark of Terumo Medical Corporation.

Technology—Principles of operation


New capillary design

  • Two capillary tubes (total volume: 240-µL) are included per kit.
  • Longer curved sample path reduces blood movement.
  • More transparent ComfortSampler® tip allows higher visibility of flash point during patient sampling.


Better sample stability

  • Capillaries are coated with balanced heparin.
  • Balanced heparin preserves electrolyte values.
  • Blood is automatically mixed with heparin as the sample is collected.
  • The sample is isolated from the transfer of body heat.
  • The sample is cooled rapidly to slow metabolic changes.



  • The 25-gauge needle has an integrated needle protector to protect the therapist.
  • Small-gauge needles reduce the risk of patient hematoma.
  • Unique design protects users from injury due to capillary breakage.
