Partitioning oil can vary in its appearance between different lots and different kits. For example, the partitioning oil in the Training Chip kit may appear cloudier than the partitioning oil in the Genome or Single Cell A Chip Kit. Different lots may also have a slightly different color. Some lots may have a darker yellow color than others. The color does not impact performance of the oil.
Near the expiration date, the partitioning oil may also become more cloudy. This is normal and does not compromise performance as long as the partitioning oil is not expired.
