Real-World Testing: Putting Kimble/Kontes Disposable Bacteriological Pipets, Glass, Sterile, Plugged 72108 10110, Case of 400 to the Test
First Use Experience
The first field test involved transferring soil suspensions to petri dishes for bacterial culture. We were working outdoors, dealing with varying humidity levels and the constant risk of airborne contaminants. Using these pipettes felt significantly more controlled than any plastic alternative I’d experienced.
The wide tip made aspirating viscous samples remarkably easy, something that smaller, less specialized pipettes often struggle with. The graduations were clear and easy to read, even under less-than-ideal lighting conditions. After the first use, I noticed the precision with which the liquids could be transferred, meaning less repeated measurements, and greater accuracy in each culture.
Extended Use & Reliability
After several weeks of near-daily use, the Kimble/Kontes Disposable Bacteriological Pipets, Glass, Sterile, Plugged 72108 10110, Case of 400 have consistently proven their worth. There’s been no compromise to the sterility of the product, which has allowed me to focus on experimentation, not error-correcting. The glass construction is surprisingly durable, resisting breakage even with the occasional accidental bump.
Maintenance is non-existent, which is precisely the point of disposable labware. Simply use and discard responsibly. Compared to the tedious process of cleaning and autoclaving reusable pipettes, these save an immense amount of time and reduce the risk of contamination. Kimble/Kontes has exceeded my expectations in providing a reliable and convenient solution.
Breaking Down the Features of Kimble/Kontes Disposable Bacteriological Pipets, Glass, Sterile, Plugged 72108 10110, Case of 400
Specifications
Capacity: 10mL. This is an ideal volume for transferring most samples and reagents in bacteriological work.
Subdivisions: 0.1mL. The fine graduations allow for precise measurements and controlled delivery of liquids.
Negative Graduations: 2mL. Extending the graduation marks below zero offers added versatility for measuring and dispensing smaller volumes.
Tolerance: ±0.30mL. This indicates the level of accuracy you can expect from the pipettes, which is crucial for reliable results.
Unit: Case of 400. Buying in bulk ensures you have a sufficient supply and reduces the frequency of reordering.
Material: Glass. The glass construction allows for greater control and less surface tension.
Sterile: The sterile design eliminates risk of outside contamination, which means less room for experimental error.
Plugged: The cotton plug prevents contaminants from entering the pipette.
Wide Tip: Ideal for viscous materials.
Performance & Functionality
The Kimble/Kontes Disposable Bacteriological Pipets, Glass, Sterile, Plugged 72108 10110, Case of 400 perform exceptionally well in their intended role. They accurately and efficiently transfer liquids, especially viscous samples, which is exactly what I needed. The two rings near the top are a crucial design element, indicating the need to blow out any remaining liquid to ensure accurate delivery.
The strength lies in their reliability, sterility, and ease of use. One area for potential improvement might be adding more distinct markings at larger volume intervals for quicker readings, though the current subdivisions are adequate. Overall, they meet and exceed expectations for a disposable bacteriological pipette.
Design & Ergonomics
The glass construction feels solid and provides a good grip. While not specifically designed for extended ergonomic comfort, the pipettes are easy to handle and manipulate during standard laboratory procedures. The clear graduations and ample length contribute to ease of use.
The single use purpose also means that there are no ergonomic concerns for long term repeated usage. The design allows the user to focus purely on the experiment being conducted.
Durability & Maintenance
Given that these are disposable pipettes, long-term durability isn’t a primary concern. However, the glass is surprisingly resilient, and I haven’t experienced any issues with breakage during normal handling. Maintenance is nonexistent; simply dispose of the pipettes after use according to lab protocols.
This allows for a far greater degree of time-efficiency, given there is no need to clean and sterilize the pipettes. The money saved in staff time and reduced likelihood of errors makes the Kimble/Kontes Disposable Bacteriological Pipets, Glass, Sterile, Plugged 72108 10110, Case of 400 a great buy.
Accessories and Customization Options
These pipettes are designed as a self-contained solution, and there are no specific accessories or customization options.
