Allinone benchtop design: accommodates tubes at the same time, combining a test tube rack holder with a test tube propagation station to streamline workflows and save benchtop space. Pipette holder for experiments: a versatile tool built from durable material, designed for laboratory use; portable pipette stand to keep pipettes organized and readily accessible. Portable pipette holder: made of stable material, durable and easy to clean; built for longterm use and suitable for manual pipette accessories. Test tube holders: compact design that efficiently utilizes space; keeps tubes organized during experiments and supports an orderly work area. Use scenario 1: in teaching or lab demonstrations, the station allows quick access to multiple tubes and pipettes, facilitating smooth instruction and handson practice. Use scenario 2: on research benches for parallel sample preparation, enabling simultaneous handling of several tubes and convenient pipette access. Use scenario 3: in field or mobile labs where a compact, portable setup helps transport and organize essential tubes and pipettes for onsite experiments.
