Real-World Testing: Putting Kimble/Kontes Shorty Disposable Serological Pipets, Glass, Sterile, Plugged, Kimble 72115 25210 Individually Wrapped, Case of 200 to the Test
First Use Experience
My initial testing ground was in our lab’s cell culture hood, crucial for maintaining a sterile environment when working with sensitive biological samples. I used these pipettes for aliquoting media, adding supplements, and transferring cell suspensions.
The pipettes performed flawlessly, even when dispensing viscous liquids, the clear graduations ensured accurate measurements every time. I immediately appreciated the short design, reducing the risk of bumping into the hood’s interior, a common problem with longer pipettes in confined spaces.
Extended Use & Reliability
After several weeks of consistent use in diverse applications, from preparing reagents for chromatography to precise dilutions for PCR reactions, the Kimble/Kontes Shorty Disposable Serological Pipets maintained their reliability. There were no instances of breakage during normal handling.
The clear, legible markings remained intact, even after contact with various solvents and solutions. Compared to the time and effort spent sterilizing reusable pipettes, these disposables have significantly streamlined my workflow, saving me valuable hours.
Breaking Down the Features of Kimble/Kontes Shorty Disposable Serological Pipets, Glass, Sterile, Plugged, Kimble 72115 25210 Individually Wrapped, Case of 200
Specifications
- Capacity: 25 mL – This generous capacity is ideal for handling larger volumes of liquids, reducing the number of transfers needed. This reduces the risk of errors and saves time.
- Subdivisions: 0.5 mL – The fine graduations of 0.5 mL enable precise measurement, vital for accurate experiments. This allows for confident and accurate aliquoting.
- Negative Graduations: 10.0 mL – This added range allows for “blow-out” dispensing, ensuring the complete delivery of the intended volume, which is crucial for many analytical techniques. This ensures no residual volume remains in the pipette.
- Tolerance: ± 1.0 mL – While not the highest precision available, a tolerance of ± 1.0 mL is adequate for many standard lab procedures. This is suitable for general laboratory use.
- Individually Wrapped and Sterile – Each pipette is sealed in its own sterile package, preventing contamination and guaranteeing a sterile environment for sensitive work. This eliminates the need for autoclaving, saving time and ensuring sterility.
- Glass Construction – Glass offers superior chemical resistance compared to plastic, making these pipettes suitable for a wide range of solvents and solutions. Glass is also easier to read than plastic.
- Plugged – The cotton plug prevents liquids from entering the pipetting device, protecting it from contamination and ensuring accurate dispensing. This prevents potential damage to pipetting devices.
- Shorty Design – The shortened design is advantageous in tight spaces such as biological safety cabinets, reducing the chance of accidental contamination. This improves maneuverability and safety.
These specifications translate to a reliable and versatile tool suitable for a broad spectrum of lab applications, particularly where sterility and accuracy are paramount. The Kimble/Kontes brand is known for quality, and these pipettes live up to that reputation.
Performance & Functionality
The Kimble/Kontes Shorty Disposable Serological Pipets, Glass, Sterile, Plugged, Kimble 72115 25210 Individually Wrapped, Case of 200 performs admirably in various laboratory tasks. The clear graduations and smooth glass surface facilitate precise and consistent liquid handling.
The pipettes consistently deliver accurate volumes, minimizing experimental errors. However, the ± 1.0 mL tolerance might be a limitation for ultra-precise applications requiring accuracy down to the microliter range. The performance meets expectations for general laboratory use, but not for demanding micro-volume applications.
Design & Ergonomics
The glass construction feels substantial and provides a solid grip, even when wearing gloves. The short design improves maneuverability in confined spaces, reducing the risk of accidental contamination.
There’s no real learning curve; they are intuitive to use for anyone familiar with serological pipettes. The glass material is also easy to read.
Durability & Maintenance
The glass construction ensures reasonable durability under normal laboratory conditions. They are intended for single use, eliminating the need for cleaning and sterilization.
However, care must be taken to avoid breakage. Maintenance is nonexistent, and the disposable nature promotes cleanliness and reduces potential contamination.
