2. **Gray stopper** - **H. Sodium fluoride, blood glucose**
3. **Syringe** - **J. Single–use venous collection device**
4. **Butterfly** - **G. Multi-sample needle for small veins**
5. **Yellow stopper** - **C. Blood cultures**
6. **Red stopper** - **I. No additive**
7. **Mustard or speckled stopper** - **D. Serum separator tube (SST)**
8. **Green stopper** - **A. Sodium heparin**
9. **Multi-sample capability** - **E. Evacuated tube holder**
10. **Anticoagulant** - **B. Hematology testing, purple stopper** (Note: While this is not a direct match for anticoagulant itself, the purple stopper is commonly used with EDTA which is an anticoagulant used in hematology testing.)
