Chill Block Portable Tube Chiller
Product Code : EL-BLS-10949
Last updated: 6 October 2026
Quick answer: A two-sided freezer-charged block that replaces an ice bucket, holding samples at approximately 0 degrees C for up to 4 hours. One side takes 36 tubes of 1.5 to 2.0 mL; the other takes 96 x 0.2 mL tubes, 12 strips or one 96-well PCR plate.
Ice buckets melt, tip, and leave tubes floating at an unknown temperature. A chilled block holds a known temperature in a fixed rack, which is what enzyme work needs: the listing states it keeps perishable enzymes and other samples cold without degradation from temperature increase or fluctuation.
Charging is simple, placed in a freezer overnight, after which it maintains samples at approximately 0 degrees C for up to 4 hours. That 4 hour figure is the one to plan around: it covers a long practical but not a full day, so a second block may be needed for back-to-back classes.
The two-sided design is what makes it flexible. One side accommodates 36 tubes of 1.5 to 2.0 mL. The other holds 96 x 0.2 mL tubes, 12 x 0.2 mL strips, or one 96-well PCR plate, plus a further 10 tubes of 1.5 to 2.0 mL. Size is 5-6/10 inches long by 5-6/10 wide by 2-1/2 high, weight 2 lb.
