Shopping for a desktop lab centrifuge often comes down to how much rotor detail you want before you spend. These two timer-equipped models both spin at 4000 rpm and target medical laboratory use. The Calu Luky spells out a 20 ml x6 rotor and a timer range, while the Segawe offers a simpler low-speed separation story at the lower end of the price spread. The right choice depends on whether you want a fuller specification sheet or a more direct buy.
Quick verdict
Choose the Calu Luky when a declared rotor capacity and a timer range are important. Its details include 20 ml per tube across six tubes, a 0-60 minute timer that can also run continuously, and a speed-control mention. Choose the Segawe when the lower end of the price spread is the priority and a simple 4000 rpm low-speed centrifuge with a timer fits the job.

Product notes
Calu Luky Desktop Electric Lab Laboratory Centrifuge Machine w/Timer
This model is the specification-rich choice. The listed details include a 20 ml per-tube capacity across six tubes, a 4000 rpm maximum, and a maximum relative centrifugal force of 1790×g. The timer can be set from 0 to 60 minutes or run without a limit, and six tubes are provided. The description also mentions speed control and a 110V AC electrical specification. The trade-off is that it is the higher-priced model in this pair. If you want the rotor capacity spelled out before you buy, this is the one to pick.
Segawe Desktop 800-1 Electric Centrifuge Machine w/ Timer
This is the lower-priced entry point at USD 56.19. The title sets the core specs at 4000 rpm and timer operation, and the description frames the machine as a general-purpose low-speed separator for suspensions, emulsions, and wet solids. The description highlights the separation job, so it is a simpler buy for users who do not need a detailed rotor spec. If you want a basic 4000 rpm timer centrifuge and the lower listed price matters more than a fuller specification sheet, the Segawe is the straightforward pick.
Final choice by use case
For a lab centrifuge with a declared rotor configuration, max RCF, and timer range, the Calu Luky is the fuller match. For a price-focused buy that keeps the core speed and timer, the Segawe is the more economical selection.
