Blood Culture
Bottle Sampling

When the sample within a blood culture bottle is found to have a positive result, it is necessary to obtain samples from the bottle for further tests to ultimately identify the specific microorganism(s) and determine susceptibility to a range of antibiotics. This subculture process is typically done by using a needle and syringe or a venting needle. These processes pose the threat of accidental needlestick injury to the technologist at multiple stages in the procedure including

  • Prior to needle insertion into the culture bottle;
  • During needle insertion into the culture bottle;
  • After needle removal from the bottle.

In each of these steps a needle or sharp is exposed and an inadvertent injury can occur. With distractions and heavy workloads, accidents can easily happen so it is wise to remove sharps from a medical procedure whenever possible.  Safer Products are available to sample blood from culture bottles.

The Safety SubCulture Unit (SCU) is a sharps safety device used to obtain samples from positive blood culture bottles. Needleless sampling reduces risk of needlestick injury.

The plastic tip safely pierces the bottle septum and makes it easy to insert and remove from the culture bottle. The integrated filter cap controls gas or culture discharge for an added level of safety.

Sampling Options
Safety SubCulture Unit offers unique dispensing options for controlled sampling. The SCU sampling channel has been designed to dispense drops directly from a tilted culture bottle.

The female luer connection allows for needleless syringe draw and dispensing technique.

The Safety SubCulture Unit (SCU) has integrated safety for subculture procedures which:

  • Reduces the risk of injury because it is needleless
  • Reduces the risk of exposure from gaseous discharge

The SCU is compatible with a variety of culture bottles.
