No Additive Tubes → used in microbiological serology. Urine Collection Tubes (Boric Acid, Chlorhexidine) → intended for microbiology, preserving bacterial viability or preventing overgrowth in urine culture samples. All are sterile, CE-marked, ISO-compliant consumables suitable for diagnostic microbiology workflows. VACUSERA No Additive Tubes Please Log In to access Additional Details and documents … VACUSERA Urine Collection Tubes They are available with Boric Acid and Chlorhexidine additives. Both are preservatives used in microbiology: Boric Acid tubes: maintain bacterial stability in urine samples during transport. Chlorhexidine tubes: prevent bacterial overgrowth.
“Vacusera no additive tubes are used in determinations for clinical chemistry and hormones, microbiological serology, and immunology. Vacusera no additive tubes do not contain any additive but are evacuated and the interior is sterile.”
These are specifically listed as suitable for microbiological serology testing.
General sterile tubes (No Additive / Serum)
➝ These are intended for urine microbiology cultures and ensure colony counts remain accurate after transport.
➝ Several are described as “sterile interior, suitable for microbiological serology,” which suggests their validated use in pathogen serological testing.
