MICROSAFE Capillary Tube

MICROSAFE collection and dispensing tubes allow for blood sample collection and dispensing from a single plastic tube.

Each tube fills easily to a preset volume using capillary action. No aspiration… no air bubbles… no wasted samples.

Dispense the sample easily by pinching the unfilled portion of the tube. There are no bulbs, dispensers or other mechanical devices necessary.

The MICROSAFE tube is ideal for finger-stick sampling and dispensing of whole blood.

MICROSAFE Collection and Dispensing Tubes are perfect for finger-stick sampling. Here’s how MICROSAFE® works: An air vent is strategically positioned on the sidewall of the tube. This allows air to vent automatically, while controlling sample volume.

Using the MICROSAFE Tube

CAUTION! Filling is automatic: Never squeeze the tube while sampling.

Don’t squeeze the bulb; MICROSAFE fills by capillary action.

Step 1: Hold the tube horizontally, and touch the tip of the MICROSAFE® Tube to the blood sample. Capillary action will automatically draw the sample to the air vent and it will stop.

Step 2: To expel the sample, align the tip of the tube wi
