Real-World Testing: Putting VWR Spacer 2MM PK2 E2110-2-S-VW to the Test
First Use Experience
I primarily tested the VWR Spacer 2MM PK2 E2110-2-S-VW in cell culture experiments involving Petri dishes and multi-well plates within a sterile cell culture hood. The spacers were used to create distinct zones within the culture vessels, allowing for the co-culture of different cell types without direct contact.
The spacers performed exceptionally well under the controlled conditions of the cell culture hood. Their epoxy coating ensured they remained inert and did not interfere with cell growth or viability, even after prolonged exposure to culture media. Using the spacers was easy; simply inserting them into the desired location after autoclaving.
The initial use revealed a slight learning curve in terms of positioning the spacers to achieve the desired separation without compromising the structural integrity of the culture setup. Initially, I placed them too close to the edge, causing a slight curvature in the Petri dish. However, this was quickly resolved with minor adjustments.
Extended Use & Reliability
After several weeks of consistent use in various cell culture experiments, the VWR Spacer 2MM PK2 E2110-2-S-VW continues to perform reliably. There have been no signs of degradation or wear, and the epoxy coating remains intact even after repeated autoclaving cycles.
The spacers have proven remarkably durable, with no chipping, cracking, or deformation observed despite frequent handling and exposure to various chemical solutions used in cell culture. Their robust construction has ensured consistent performance, and the epoxy coating resists degradation well.
Maintenance is straightforward; the spacers are easily cleaned with standard laboratory detergents and can be sterilized by autoclaving or exposure to UV light. No special care is required, making them a hassle-free component of my workflow. This ease of maintenance is a huge plus.
Compared to my previous methods of using makeshift dividers, the VWR Spacer 2MM PK2 E2110-2-S-VW significantly outperforms in terms of reliability, consistency, and ease of use. It has streamlined my experimental setup, improved data reproducibility, and reduced the risk of contamination. The consistency is the biggest improvement.
Breaking Down the Features of VWR Spacer 2MM PK2 E2110-2-S-VW
Specifications
The VWR Spacer 2MM PK2 E2110-2-S-VW is defined by its key specifications. The “2MM” in the name indicates its 2mm thickness, which is crucial for creating precise separations. Being sold in a “PK2” suggests that it comes as a pack of two spacers.
The epoxy coating is another significant specification. This coating ensures the spacers are chemically inert and resistant to common laboratory chemicals, preventing contamination of the experiment. The expandable plastic material provides flexibility for easy insertion into various containers without causing damage.
The specific material of the expandable plastic is essential because it should be autoclavable, meaning it can withstand high-temperature sterilization without deforming or releasing harmful substances. The epoxy coating is also crucial for being non-cytotoxic, meaning it won’t harm cells in culture.
Performance & Functionality
The VWR Spacer 2MM PK2 E2110-2-S-VW excels at its primary function: creating precise and consistent separations in laboratory settings. It reliably maintains a 2mm gap, enabling controlled co-culture experiments and other applications where spatial control is essential.
