Alkali Scientific Microhematocrit Capillary Tube, Glass, Blue Tip, Plain Non heparinized(Untreated), 1000/Pk, 70 µL, 75mm Length
Microhematocrit Capillary Tubes are manufactured from high quality precision glass to support reliable blood transfer and accurate micro hematocrit determinations in clinical and research laboratories. These plain (untreated) capillary tubes are designed for collecting anticoagulated blood directly from blood collection tubes as part of standard hematology testing workflows. The uniform internal bore promotes rapid capillary filling while preserving specimen integrity. Precision manufacturing ensures consistent dimensions and excellent sample retention during centrifugation. Tubes are suitable for micro hematocrit testing at speeds up to 14,500 RPM for approximately 5 minutes. For laboratory efficiency, the tubes are packaged with 100 capillary tubes per vial and 1,000 tubes per pack, supporting high volume hematology testing environments.
Alkali Scientific Borosilicate Glass Culture Tubes (DCTs) 1000/Case, 13x100mm (10mL)
Alkali Scientific™ borosilicate glass culture tubes provide reliable performance for clinical, research, and industrial laboratory applications. Made from high quality chemically resistant borosilicate glass, these tubes reduce pH changes and help prevent contamination, making them ideal for sensitive procedures such as tissue culture, blood banking, and sample storage. Each tube includes a smooth fire polished rim and rounded bottom to support safe handling and consistent experimental results. Precise manufacturing standards ensure compatibility with standard laboratory racks, centrifuges, and automated systems. Tubes are packaged in four shrink wrapped boxes of 250 tubes each (1,000 total) to maintain product cleanliness, reduce particle exposure, and simplify laboratory storage and dispensing.

Alkali Scientific™ offers high quality borosilicate glass culture tubes designed for reliable performance in clinical, research, and industrial laboratories. Manufactured from chemically resistant borosilicate glass, these tubes minimize pH shifts and contamination risk, making them suitable for sensitive applications such as tissue culture, blood banking, and sample storage. Each tube features a smooth fire polished rim and rounded bottom for safe handling and consistent experimental results. Rigid dimensional standards ensure compatibility with common racks, centrifuges, and laboratory automation systems. Tubes are packaged in four shrink wrapped boxes of 250 tubes each (1,000 total) to maintain cleanliness, protect from particles, and support efficient laboratory storage and dispensing.
Alkali Scientific Borosilicate Glass Culture Tubes (DCTs) 1000/Case, 16x100mm (14mL)
Alkali Scientific™ borosilicate glass culture tubes are engineered for reliable performance across clinical, research, and industrial laboratory environments. Produced from chemically resistant borosilicate glass, these tubes minimize pH fluctuations and help reduce contamination risk during sensitive laboratory processes such as tissue culture, blood banking, and sample storage. A smooth fire polished rim and rounded bottom support safe handling and consistent laboratory performance. Tight dimensional tolerances ensure compatibility with standard racks, centrifuges, and laboratory automation systems. Tubes are packaged in four shrink wrapped boxes of 250 tubes each (1,000 total) to preserve cleanliness, protect from contamination, and allow convenient storage and dispensing in laboratory workflows.
Alkali Scientific Saline 0.85% 9.9mL Screw Cap Tube, 10/Pk
Saline 0.85% is a sterile isotonic sodium chloride solution used to maintain cell viability during laboratory procedures. The solution provides osmotic stability that prevents microbial cells from lysing or shrinking during dilution and mixing. This specialized 9.9mL screw cap tube is calibrated to simplify high factor dilution protocols. When 0.1mL of a sample is added, the tube produces an immediate 1:100 dilution in a single step. This eliminates additional dilution stages and improves workflow efficiency in microbiology laboratories. The secure screw cap allows safe vortex mixing and transport, making the tube suitable for microbial enumeration, sample preparation, and routine dilution procedures.
