Blood Gas Capillary Collection Device

We have found that the blood gas capillary collection device has been discontinued, SAFET-T-FIL Blood Gas Capillaries by RAM Scientific. These do not have a "flea" or "mixing stick" in them. What do you use for capillary blood gas collection that would not come with the use of a mixing entity?

As always...love this community! Please share your knowledge with me.

Thanks,
Erika

We use the Werfen 170 uL heparinized capillary tubes (00008217000).  There are 100 per vial.  They do not contain a flea and it does not include caps.  We use the RAM Scientific end caps (MFR# 06 0402).  There are 500 per box.
