Long Glass Test Tubes

Extended Tube Body Meets Special Lab Requirements with Long Glass Test Tubes

 

We have 12 years of professional production experience in lab glass consumables, and product are designed for special lab operation needs such as deep reaction, layered experiment and long-distance sample transfer. These tubes are widely used in organic chemical synthesis, biological chromatography and teaching demonstrations, and their extended design can meet the needs of large-volume layering and deep reaction while effectively avoiding sample overflow. They are a necessary consumable for labs with various special experiment scenarios.

We use lead-free and arsenic-free borosilicate 3.3 glass to make these tubes, and the material has stable chemical properties that can withstand temperature changes from -18℃ to 140℃ without cracking from thermal shock. We adopt full automatic precision tube drawing technology, which ensures the extended tube body is straight without bending or deformation, and highly transparent without bubbles or impurities. We carry out 100% full inspection, with an outer diameter error of ≤0.15mm and a length error of ≤0.3mm for each tube to ensure precise specifications.

The clear capacity scale on the tube body has a reading error of ≤0.8%, which helps you control sample dosage accurately for special experiments. The round bottom design allows the tubes to be placed on extended test tube racks, and the tube mouth fits well with rubber or cork stoppers for good sealing. You can clean the tubes repeatedly and conduct 121℃ high-pressure sterilization, and they have strong corrosion resistance to strong acid, strong alkali and organic solvents. We provide a three-year warranty, support customized length specifications for bulk orders, and ensure stable supply to meet your large-scale special

experiment needs.
