0.5 mL K3EDTA Polystyrene Blood Collection Tubes (9×30 mm) – 3K1230

Reliable Small-Volume Blood Collection Tubes for Hematology

The 3K1230 blood collection tube is a mini 0.5 mL specimen container designed for precision and safety in hematology and diagnostic workflows. It’s made from clear polystyrene, with a 9×30 mm external dimension, and supplied with a pink skirted cap containing the anticoagulant K₃EDTA. Ideal for small sample volumes such as paediatric, micro-sampling or point-of-care blood draws.

Key Features

• 0.5 mL capacity – minimizes blood draw while yielding sufficient sample for many assays

• K₃EDTA anticoagulant – supplied either as a dried coating in the base or with a wet droplet, stabilises blood by chelating calcium

• 9×30 mm size – compact dimensions, easy to store and handle, fits mini racks or small centrifuge buckets

• Polystyrene material – clear transparency for visual inspection of blood and cellular components

• Temperature range −4 °C to +60 °C – stable during typical lab storage or transport conditions

• Centrifugation rating up to 1500 g – suitable for many routine centrifuge protocols

• Pink skirted screw cap – colour coded for EDTA tubes, secure sealing to reduce contamination risk

Why Choose the 3K1230 Tube?
