Universal Voltage

Operates on 100-230V, 50/60Hz, streamlining procurement and qualification strategies from early R&D to global clinical trials.

Setpoint Expansion

Users can now enjoy an expanded setpoint range of up to -40°C, a first for the TSX Series ULT platform.

Faster Re-Entry

An improved pressure relief port (PEP) enables re-entry in just 30 seconds, 57% faster than previous TSX ULTs, helping ensure uninterrupted freezer access.

Whisper-Quiet

Operating at under 44 decibels, the TSX Universal ULT can be placed anywhere, singly or in multiples, without causing sound pollution.

The new TSX Universal Series ULT freezers feature the innovative Universal Variable Drive (V-Drive) technology, marking a significant advancement in performance and energy efficiency. Unlike standard compressors that operate in a binary full-power or nothing mode, the Universal V-Drive adjusts its speed variably to achieve optimal cooling capacity while maximizing energy efficiency.
