Saunders® Hygenic/Asceptic Diaphragm Spares

Saunders® HC4 Diaphragms are developed, compounded and manufactured entirely in-house. Saunders® elastomer and PTFE diaphragms are ideally suited for demanding bio-pharm applications, including: compendium waters, process, CIP and SIP.

All HC4 Diaphragms conform to FDA, USP and ASME BPE Standards and are ADCF and fully lot traceable.

Description

SAUNDERS® ER Resilience Elastomer Diaphragm – Saunders® elastomer diaphragms consist of a range of proprietary materials specifically developed by Saunders® team of in-house polymer technologists to meet the demands of Life Science applications.

Features And Benefits

  • Excellent mechanical strength and good all round resistance to Life Science process and utility applications
  • Full batch traceability provides maximum security, reliability and repeatable performance
  • Organic peroxide cured for reduced extractables and leachables
  • Full global compliance and testing to FDA, USP Class VI and BSE/TSE

SAUNDERS® EX Endurance Diaphragm – Saunders® EX Endurance Diaphragm is a unique material combination which offers outstanding performance in applications exposed to prolonged sterilisation regimes, or higher temperature up to 175°C (347°F).

Features And Benefits

  • Outstanding high temperature performance and resistance to long term exposure at elevated temperatures
  • Ideal for steam distribution and supply, sterile barrier, and block-and-bleed applications
  • Improved seal-to-atmosphere performance and reduced requirements for re-torqueing of fasteners after thermo cycling

SAUNDERS® PR Pure Resilience PTFE Diaphragm – Saunders® PR Pure Resilience diaphragms are robust two piece leaf type. The design incorporates a virgin PTFE wetted face backed with a fabric reinforced support diaphragm.

Features And Benefits

  • Stud anchorage is fully encapsulated to ensure maximum strength and lifetime in service
  • Full batch traceability provides maximum security, reliability and repeatable performance
  • Industry conforming low level of extractables and leachables

SAUNDERS® PV Passivation Diaphragm – Saunders® PV Passivation Diaphragm is a dedicated “single use” elastomer diaphragm developed for passivation service of stainless steel Biopharm systems. The design is manufactured from FDA/USP compliant elastomer and is supplied with bayonet attachment for interchangeability with Saunders® PTFE/TFM range.

Features And Benefits

  • Reduced cost and TCO (Total Cost of Ownership) benefits versus single use of PTFE diaphragm
  • High visibility tag reduces risk of diaphragm not being replaced after passivation
  • Materials suitable for use with citric acid and EDTA-based passivation chemicals and typical post passivation clean and rinse solutions

SAUNDERS® SR Steam Resilience TFM Diaphragm – SAUNDERS Life Science Modified PTFE (TFM) diaphragms are robust two piece leaf type. The design incorporates a TFM wetted face backed with a fabric reinforced support diaphragm.

Features And Benefits

  • Significant reduction in creep and deformation under aggressive sterilisation regimes
  • Increased resistance to permeation compared with standard PTFE
  • Full batch traceability provides maximum security, reliability and repeatable performance
