0.5 mL K₂EDTA Polystyrene Blood Collection Tubes (9×30 mm) – K1230
Small-Volume EDTA Tubes for Reliable Sample Collection
The K1230 is a 0.5 mL blood collection tube made from clear polystyrene, treated with dry K₂EDTA anticoagulant (~0.88 mg per tube, equivalent to ~1.75 mg per mL of blood). It features external dimensions of 9×30 mm, and comes with a pink, skirted screw cap. Ideal for minimal-draw sampling, paediatric use, or any application where conserving blood volume while maintaining diagnostic integrity matters.
Key Features
-
Volume: 0.5 mL — perfect for small blood draws or micro-sampling.
-
Anticoagulant: K₂EDTA (dry form, ~0.88 mg per tube) — helps preserve cellular components and prevents clotting.
-
Material: Polystyrene — clear for easy visual inspection of sample color, clarity, and possible clot formation.
-
External Size: 9×30 mm — compact footprint fits many racks, centrifuge holders, or diagnostic analyzers.
-
Cap & Colour: Pink skirted screw cap — standard EDTA colour coding to simplify lab workflow.
-
Temperature Range: −4 °C to +60 °C — safe for standard lab storage, ambient handling, and routine transport.
-
Centrifugation Rating (RCF): Up to ~1,500 × g — adequate for most EDTA separation protocols.
-
Packaging: Supplied in packs (e.g. 100 / 500 / 1,000 tubes) — supports both small labs and high-volume use.
